Curt Double Lock Gooseneck Hitch Operation

Curt Double Lock Gooseneck Trailer Hitch Operation

The Curt Double Lock underbed gooseneck trailer hitch provides a sturdy, secure connection for towing your gooseneck trailer and also allows for a clean, unobtrusive look for your truck bed when you aren't towing. To tow, simply pull the included handle out to unlock the hitch. Then insert the chrome-plated hitch ball into the ball hole. You may need to rotate the ball to line it up with the dual locking pins. When the ball drops into place, rotate the handle counterclockwise until the locking pins snap into position. Because there are 2 locking pins instead of 1, you get extra security for your towing setup.


Get full bed access when you're not towing. Just remove the ball, flip it upside down, drop it back into the ball hole of the hitch, and use the handle to lock the ball in place. A rubber cover is included with the Double Lock. When the ball is stowed upside down in the hitch, place this cover over the ball hole to keep out dirt and grime and create a clean look for your vehicle.

Video Transcript for Gooseneck Trailer Hitch Installation - 2009 Chevrolet Silverado

Today, in our 2009 Chevy Silverado, we'll be installing the CURT Double Lock Gooseneck Hitch, part number C615-632. Next, let's go ahead and go to the operation of our new gooseneck hitch and ball. To release the handle, we'll pull out, rotate it to the unlock position. Then we can install the ball. To install the ball, we'll lineup the groove in the ball with the nipple in the gooseneck cylinder. We'll drop the ball in place and then release the handle locking the ball to the gooseneck.

Again, we can release by pulling out and rotating to unlock it, pull the ball out, turn it over, re-secure the handle and install the gooseneck cylinder cover for the stored position.We'll go ahead and install the gooseneck hitch. To begin our install, we're first going to go ahead and lower remove the spare tire and remove both rear wheels. This will give us more room to make it easier to do the install. Next, we need to remove the heat shield above the exhaust starting at the forward hat channel we'll cut it just behind the hat channel with the rotary cut off wheel. We'll go to the end of the heat shield and cut it just in front of the rear hat channel.

The center section of the heat shield is secured with 2 fasteners. Overtime these fasteners will become very difficult to remove.First, we'll go ahead and attempt to remove them. However, if they strip out, we'll then go ahead and use our cut off wheel to just cut the head of the screw and then remove the heat shield. With our heat shield down all the way, we'll move to the bed. We'll measure for the length per the instructions and then measure for the center width of the bed marking for our pilot hole.

With the bed marked, we'll go ahead and drill out our pilot hole. Next we'll step up to our hole saw and drill out the large hole. Now we've gone through the bed, you'll see that the hat channel covers a small portion of the hole.We can use the hole saw to go ahead and cut out this section of the hat channel. With our hole cut out, we'll move down to the frame rails. Here we'll need to relocate any wiring or brake lines that's secured to the top of the frame rail above the axle.

With the wiring out of the way, we're ready to install the rear rail for our gooseneck hitch. As you put the rail in position, we'll make sure that the pre-drill threaded holes face down. We'll install the forward rail. We'll make sure that the pre-drilled holes in the end that are offset face downward. We'll slide it in between the pickup bed and frame and then rotate it up into place.Using a crescent wrench can make it easier to rotate it into position. With our rails in place, we're ready to install the gooseneck head. To make it easier to do this and hold this head assembly into position we'll be using the CURT install tool for gooseneck hitches, part number C60606. This install tool will sit in the pickup bed with an L bracket that will go down to our cut out hole in the pickup bed we'll lock in the throat the same as a hitch ball. Then we can use the threaded bolt that runs to the L bracket to pull the head up into place and hold it while we install our hardware.This will be the 1/2-inch bolt split lock washer and flat washer. We'll install each fastener finger tight until we have them all in place. Next, we'll move to the wheel wells where we'll install side brackets. The side brackets will get secured to the frame using the 3/4-inch bolt and flat washer that will go through the side bracket. Then we'll add two large round spacers feed it through the manufacturer's hole in the frame. We'll secure it with the large spacer block and then a 3/4-inch flange nut. To secure the side bracket to the frame rail, we'll use a 1/2-inch bolt split lock washer and flat washer.Next, we'll take the U bolt and feed it from the inside around the frame and through the side bracket and secure it with the 2 1/2-inch flange nuts. Now, with all our hardware installed finger tight, we're ready to go ahead and start tightening it down. We'll repeat the same procedure starting with the head units of the rail assembly, side brackets to the frame and then the side bracket to the rail. We're ready to start torque it to the manufacturer's specifications. We'll need to re-secure the brake line bracket. We'll use the extension provided with our install kit.We'll take the extension and manufacturer's fasteners and secure it to the frame. Then we'll take the new 8-milimeter bolt and flange nut and secure the manufacturer's bracket to the CURT bracket. Next, we'll re-secure the wiring. If you're unable to reinstall it into the frame, we'll go ahead and use a couple of zip ties to secure the wire we remove from the frame to the main harness. Then we'll cut off the excess from the zip ties to clean up our install look. Now, we're ready to install our chain holes down. Using the hitch as template we'll pre-drill holes into the bottom corrugation of the bed and then enlarge it to our final size of half inch.Once we have holes drilled out, we'll move to the top of the bed where we'll drop the U bolts down through the holes we just drilled out. Next, we'll move back underneath the bed where we'll install a flat washer spring, second flat washer and then a nylon locking nut. Once we have all the hardware installed for the chain holes down then go ahead and tighten the buts down to where the nut is flushed with the bottom of the U bolt. With our chain holes down in place, we're ready to install the handle and lock. Our double lock will go straight into the head unit.Then our handle will go between the pickup bed and frame past to the two pre-drilled holes in the head assembly where we'll install a flat washer, spring, a second flat washer and the handle will go into the double lock. We'll line up the pre-drilled holes and install the bolt and nylon lock nut and secure the handle to the lock assembly. Note on applications where the handle assembly will hit the bed in order to operate the handle, you may need to make a small cut out. Using a pair of tin snips, we'll cut a small V in the bed to allow more room for a handle assembly to operate.We'll go ahead and reinstall the wheels. And that will complete our install of the CURT Double Lock Gooseneck Hitch, part number C615-632 on our 2009 Chevy Silverado. .

Could be packaged better. The parts are heavy and rub on each other and in some cases the finish was scraped off. Had to chase the holes with a 1/2" tap, because the finish on the hitch was sprayed into the holes. Directions were ok. Hitch fits fine and works well on my 1/2 ton Chevy. The person I worked with at etrailer.com was helpful and the hitch was shipped promptly. 555980

I order a few hitchs from etrails they always show up fast to my door. I install a curt trailer hitch on my 1996 dodge ram 2500 install was fast and easy took me about 20 mins. Now I have order this curt goose neck hitch for my 1996 haven't got to install it yet but will in the next day. I am sure the install will be fast and clean like the trailer hitch was. Anyone looking to order from etrailers do so. You can not beat there prices and the shipping is fast. Thanks etrailer 444377

No issues with this hitch after one year. I don't have a need to hide the ball so I can't comment on how easy that part works. (I thought I would need to hide the ball - but, have found that I just don't use the truck bed that way very often!) 446178

Great product, easy install. E-trailer shipped it fast but when I received my hitch UPS destroyed the box in transit and I was missing a lot of stuff.

This company helped me from step 1 on deciding which gooseneck hitch to go with, installation videos and checking up on after receipt of the hitch. The hitch was super easy to install with the template for drilling the hole that was included, this hitch by far exceeds the little extra touches you get with a more expensive hitch, the pull handle is a heavier gage, the double locking pin, and even the dust cover to keep out the dirt and gravel from the turnover ball! Great product 378880

I ordered my hitch on Tuesday afternoon and received it Friday morning. Saturday morning I put it took about 3 1/2 hours to install which included 45 minutes to get the lock off the spare tire. Struggled to get the bolts in the frame but other than that everything went smooth. It looks real nice in the bed of my 2500 chev. Now to finish lunch and hook onto the trailer and go. 478582

It’s been one year since I installed this gooseneck hitch on my truck. The video was straightforward and I was able to install an afternoon. Since then I have towed my horse trailer several thousand miles in all sorts of climates and conditions with absolutely no issues. Only suggestion , Is make sure every six months or so you lube the height of all lever and mechanism to prevent sticking. I installed this hitch for a fraction of what all the local trailer and towing stores quoted me. 546020

Review from a similar Curt Double Lock in Gooseneck


Might be a good hitch for a single rear wheel gasoline truck but is a nightmare to install on a DRW diesel truck. C-brackets are a pain with fuel tank. No room to get tools in etc.. Lessons learned............. Drop the spare, remove the rear wheels, remove the exhaust from the cab back. The instructions and the video both state that you don't have to any of the above. Yeah right. He also demonstrates removing the ball by turning the release handle to the left to lock it while you remove and replace the ball........... Handle is bolted in rigid and does NOT rotate. I don't see any way to lock it open either. (tarp strap to the fender maybe?) You can put the ball in pretty easily but removing will require 2 people as near as I can figure. Pre sale looked pretty good but........... etrailer on the other hand is still a great company to purchase all trailer needs from. Fast prepaid shipping etc.. Will continue to purchase from etrailer but not too sure about this particular brand of hitch. 572328

Review from a similar Curt Double Lock in Gooseneck


The box was beat up very bad but nothing was missing, just too heavy for UPS to carry. The installation was a little different for me than the videos I watched, on my 2003 Silverado 1500HD the right shock and gas tank was too close to truck bed and it made putting the under bed plate in very difficult, I should have just taken truck bed off. The cross bars that the under bed plate bolted in was very hard to get bolts into even after I cleaned the bolt hole threads out and sprayed WD40 into the bolt holes. It took me by myself almost 5 hours to get it installed but I got it in last Saturday, I will never do this again. 514983

Hitch seems to be working properly. The instructions were a bit hrs to follow, but with the use of a hammer and a little know how everything fit. I have a plastic bedliner, so instead of guessing where to drill the 4" hole, I just removed the liner to drill hole, then replaced it before installing the hitch. 2012 Toyota Tundra Double Cab 6.5 ft.

Easy to install, especially after watching the installation video. Hitch works great with no issues! The flush mount design to the bed allows me to remove the ball and use the space for other cargo without a "bulge" in the center of the bed. I am very happy with the hitch and would suggest it to others! 369798

I have installed this hitch and the B&W equivalent on identical trucks. The B&W is about $100 more but took me less than half the time to install. They are very similar but in my opinion the B&W is worth the extra money if you are I talking it yourself. 478729

Hitch showed up sooner than I anticipated. Install was straight forward, everything went together extremely easily. Fit finish, and level of craftsmanship was top quality, install took about 2.5 hours in my driveway, with basic hand tools. Absolutely outstanding American made product, made sold and serviced in the USA. I really believe the top quality finish and engineering of this hitch made it install so easily. 396064

Seems very well built. Fit and finish are great. I installed on a 2015 Sierra with the EZr mounting bracket and the only downfall of the combination was a very difficult installation...think bottle jacks and hammers. 504346

Curt and Pollak make a great product and etrailer is a great site, I come here for all my towing needs now! My only issue is that the instructions for the gooseneck hitch were kind of vague. I got it on in about 3 1/2 hours taking my time and making sure it was right. Other than that I would purchase a Curt and Pollak product again! 454991

The directions could be a little better for the install kit. The kit is for a 99 and newer f250. Mine is a 2016. The fit was questionable. But turned out good. Would be nice if it had a template for the safety chains to use as a guide. Too much stuff in the way under the truck to get a good clear shot at them. All and all I am very happy with it. I don't install this type of stuff all the time. But can be done right. Just take your time. Thanks. 320655

Haven't installed, but product was shipped extremely fast. Components are very well built and nothing was missing. The installation video said to tap the installation holes with a 1/2-13 tap prior to install to remove overspray from coating. This is very good advice as 1/2 inch bolts will thread in but give resistance the whole way in if coating isn't removed with the tap. Mine was shipped in two boxes making it easier to handle than having all the weight in one box. Overall I believe this is a very good product at a very good price. I also ordered a 7 blade Hopkins wiring kit #47210. This was also well built. The only purchase I had to make was the self tap mounting screws as mounting hardware is not included. 430437

Review from a similar Curt Double Lock in Gooseneck


The product looks like it's great and delivery was very prompt but one of the packages was all torn and we still don't know if we have all the parts since we haven't put it together yet. The bag with the nuts and bolts in it was torn and were spilling out of the opened end of the box when it was delivered. We are concerned that some might be missing. 501315

Product came with some packaging damage, and a few things were missing. I called customer service and they were very quick to resolve the problem and send me out new hardware and the missing parts. Overall a great experience and will buy from them again in the future. 494630

  • Recommended Curt Gooseneck Hitch for 2018 Chevy Silverado 1500 with 5-1/2 Foot Bed
  • I do have a solution for you, however the Curt Double Lock Underbed Gooseneck Hitch # C607-604 referenced in your question is only designed to fit the 2018 Silverado 2500 or 3500 that features a longer bed. It will not work on your Silverado 1500 that has the 5-1/2 foot bed. For the Curt Double Lock Gooseneck Hitch that is designed to fit your truck you instead need the part # C615-632. This is confirmed to fit and includes custom brackets that use existing holes in the truck's frame...

  • How to Determine if a Short Bed Truck Will have Enough Clearance to Make Tight Turns
  • The issue you will run into is that when you go to make tight turns the storage area on your trailer (depending on the dimensions of it), will most likely hit the cab of the truck since your truck bed is so short. Here is a formula you can use to determine if you have the needed clearance. (A + B) - C = Clearance A = Distance from the gooseneck ball to the truck cab B = Offset used, like if you used a Offset Extension Ball # 19308 C = Width of the nose of the trailer divided by 2. I...

  • Is Curt Gooseneck Hitch Compatible With Air Bags on 2017 Chevy Silverado 1500 Short Bed?
  • I can confirm for you that yes, the Curt Gooseneck Hitch # C615-632 will work with the Air Lift LoadLifter 5000 # AL57204 as well as # AL88204, with the only difference being the internal jounce bumpers that are on the # AL88204 kit. These kits contain instructions (which are linked for you) for installation on trucks with a gooseneck like your 2017 Chevy Silverado 1500 will have. I also recommend checking out the Air Lift WirelessONE Compressor System for Air Helper Springs # AL25870...

  • Can a 2008 Chevy Silverado 1500 with a 5-1/2 foot bed Tow a Gooseneck Stock Horse Trailer
  • The Curt gooseneck hitch part # C615-632 that you referenced has been confirmed as a fit for your 2008 Chevy Silverado 1500 with a 5-1/2 foot bed. Since you said the horse trailer is a stock trailer that would typically mean that the nose of it does not have a storage area or living quarters and that the front of the trailer would come to a very narrow point where the coupler installs. I attached a picture that shows the style of gooseneck trailer that would work on a truck with as short...

  • Can 2018 GMC Sierra 1500 5-1/2 foot Bed Tow Gooseneck Trailer
  • For a truck like your 2018 GMC Sierra 1500 that has a 5-1/2 foot bed it's typically not recommended to try and tow a gooseneck or fifth wheel hitch trailer. Unless the nose is tapered like a stock trailer where there's essentially no nose you'll have turning clearance issues. If the nose is tapered like that we have the Curt gooseneck hitch part # C615-632 as a confirmed fit which will work well. This hitch gives you a setup where you can flip the ball upside down when not needed and is...

  • Gooseneck Ball Hitch For 2016 Chevorlet Silverado 1500 With 5-1/2 Foot Bed
  • We do have gooseneck hitches that will fit a 2016 Chevorlet Silverado 1500 truck with the 5-1/2 foot bed. However, the Curt hitch model # C61301-52 that you referenced is an over the bed hitch that was not designed to fit in a 5-1/2 bed. If you are looking for an over the bed gooseneck ball hitch the Curt Overbed, Folding Ball Gooseneck Trailer Hitch with Installation Kit, # C61331-52 is designed to fit a 2016 Chevy Silverado with the 5-1/2 foot bed.

  • What are Determining Factors for Figuring Out if Truck and Gooseneck have Trailer Turning Clearance
  • With a 5-1/2 foot bed you would need all the offset you could get to make a 90 degree turn honestly. There are two determining factors for whether or not you need an offset. The first is the width of the nose of your trailer and then the distance from the center of the gooseneck ball to the truck cab. If the front of your trailer is very narrow you would have your best chance of making a sharp turn. If the trailer has living quarters or a square nose at all then you would be out of...

  • Recommended Gooseneck Hitch for a 2008 GMC Sierra and Trailer with a Ranch Hitch 5th-Wheel Adapter
  • I would recommend the Curt gooseneck hitch kit # C615-632 for your truck, which will work whether you have a 6-1/2 or 8 foot bed on your 2008 GMC Sierra. Please note that if your truck has a 6-1/2 foot bed, you should be using a fifth wheel to gooseneck adapter that has an offset to give you enough clearance in tight turns. Ranch offers the offset section as a replacement part # AM3140, if needed. It would be a good idea to purchase the Ranch Hitch safety chains, part # AM3109. You may...

  • Fifth Wheel Towing Setup Recommendation for a 2011 Chevy Silverado 5-1/2 foot Bed
  • Since your truck has a 5-1/2 foot bed the only way you are going to be able to tow a fifth wheel trailer is if you go with a fifth wheel rail kit and hitch plus a Sidewinder pin box on the trailer. There's no offset hitch or adapter for the gooseneck route that would allow this to happen. First you will need to start with a rail kit. For that you would want to go with a custom install kit that will minimize drilling when compared to a universal kit like the part # RP50064-58. For...

  • Best Gooseneck Trailer Hitch for 2012 GMC Sierra 1500 With 5-1/2 Foot Bed
  • The best gooseneck trailer hitch for your 2012 GMC Sierra 1500 with a 5-1/2 foot bed is the Curt Double Lock, Flip and Store Underbed Gooseneck Hitch w/ Installation Kit # C615-632 because of its completely secure system which locks the hitch ball into place with two locking pins as opposed to the standard single-pin mechanism. This hitch will also install in your '12 Sierra without needing to drill into your frame brackets; I have added a link to a video of this hitch being installed...

  • Where is Gooseneck Hitch Ball Location for Curt Double Lock # C615-632 on a 2008 Silverado 6-1/2 Bed
  • If you look at the first page of the linked "alternate" installation instructions for the Curt Double Lock, Flip and Store Underbed Gooseneck Hitch w/ Installation Kit # C615-632 you will see that it has a few different bed length options. Since your 2008 Chevrolet Silverado has a 6-1/2 foot bed you will want to look at the measurement for the 78.80 inch bed installation. If you measure from the back of the truck box (not the tailgate) then you will want to measure 42-7/16 inches towards...

  • Parts Recommendation to Tow a Fifth Wheel Trailer with a 2014 Chevy Silverado 1500 5-1/2 ft Bed
  • You can tow a fifth wheel trailer with your 2014 Chevy Silverado 1500 with a 5-1/2 foot bed. First you will need a rail installation kit. For that you will want the Reese Fifth Whee Installation Kit part # RP50064-58. This is a custom install rail kit that will install in about half the time as a universal kit and will minimize drilling. Since your bed is so short you will need a hitch with a Sidewinder to be able to make 90 degree turns. For a hitch I would recommend the Reese Fifth...

  • How Does Curt Gooseneck Trailer Hitch and Install Kit C615-632 Attach to a 2009 Chevy Silverado
  • The Curt gooseneck trailer hitch # C615-632 bolts to rails included with the installation kit and the rails are attached to brackets that bolt to the outside of the truck frame rails. I have included a link to the instructions for you and a picture that is basically a diagram showing how it attaches to the truck.

  • Using Air Lift Air Bags with Curt Gooseneck Trailer Hitch on a 2012 GMC Sierra 1500
  • Yes. If you replace the U-bolts used in Air Lift air bags # AL88204 with the bolt as indicated in the instructions it will be compatible with the Curt Curt Double Lock, Flip and Store Underbed Gooseneck Hitch # C615-632. If your truck is a short bed then the approximate distance from the back of the cab to the center of the ball is 35 inches. On a long bed that distance is 47 inches. At some point you will need to make a 90 degree (or more) turn. If you are towing a 5th wheel trailer...

  • Can the Air Lift # AL57204 Install on a 2009 Chevrolet Silverado 1500 with a Curt Gooseneck Hitch
  • I did some checking and it looks like the Air Lift LoadLifter 5000 Air Helper Springs # AL57204 are compatbile with both of the Curt gooseneck options, part # C61331-52 and part # C615-632, for your 2009 Chevrolet Silverado 1500 5-1/2 foot bed. A lot of air bag kits install using the same mounting holes along the frame that a 5th wheel or gooseneck hitch would use. This is why you were seeing that most of them say they are not compatible.

  • Under Bed 5th Wheel Trailer Hitch Installation Kit for a 2015 GMC Sierra 1500 Short Bed
  • Reese does not offer an under bed 5th wheel installation kit for your 2015 GMC Sierra 1500. The least expensive under bed and hitch option is going to be from Demco using installation kit # DM8551008 and HiJacker hitch # DM8550022 for a short bed. Another option is to use Curt gooseneck hitch # C615-632 and X5 adapter # C16210. The X5 adapter fits in the gooseneck ball hole for this gooseneck hitch and provides standard rails to mount a hitch.

  • Does Spray-In Liner Change Measurement When Installing Gooseneck Hitch On 2009 GMC Sierra
  • Since the measurement needed when installing the Underbed Gooseneck Hitch, part # C615-632 requires you to measure from the rear of the truck bed, you will need to make sure you measure the distance taking into account the spray liner if it is on the back edge of the truck bed. If it is 1/8 of an inch you need to add that 1/8 inch to the measurement for the 4 inch hole to be drilled in the truck bed.
