Features to know about

Lighten the Load Without Losing Strength: 20,000 lbs GTW and 5,000 lbs Vertical Load

This hitch is built for real hauling—rated at 20,000 lbs gross towing weight and 5,000 lbs vertical load limit. Even with that strength, it weighs just 84 lbs, making it one of the easiest heavy-duty fifth-wheel hitches to handle. The black powder coated steel frame stands up to corrosion and road grime so it’ll hold steady through long hauls and rough roads.

Hook Up Fast and Easy: Funnel-Style Head with Ball Adapter

Getting lined up is simple thanks to the open funnel design on the hitch head. From the cab, it’s easy to see as you guide the ball in, so you’re not jumping in and out to check alignment. The coupler bolts around your trailer’s king pin to create a direct connection point, cutting out the guesswork when you back into position. That setup makes coupling quick and repeatable every time you tow.

Clear Your Bed in Minutes: Two-Piece Lightweight Design

When the trip’s done and you want your bed space back, just pop the hitch out. Its two-piece design splits the weight for easier lifting, no tools needed. At under 100 lbs total, it’s simple to remove and store without heavy equipment. That modular layout makes switching from towing duty to an open bed a fast job instead of a chore.

Set Up Your Perfect Ride Height: 15-3/4" – 18-3/4" Adjustable Range

Dialing in level towing is straightforward with the adjustable hitch height between 15-3/4" and 18-3/4". That range helps match your trailer setup while keeping good bed rail clearance. Plus, it adds an extra 3-1/2" of cab clearance so there’s room for turns without worry of contact or binding.

Built for Real-World Use: SAE J2638 Tested and Backed by a 5-Year Limited Warranty

Every component meets SAE J2638 standards, so it’s proven for heavy towing performance. The sturdy construction and tested design mean it’s ready for serious mileage under load. And with a 5-year limited warranty, you can rely on it trip after trip knowing it’s built to handle demanding use.

Video Transcript for Review of PullRite 5th Wheel Hitch Rails - Custom Brackets - PUL77RR

Hello, everybody. This is Jeff at etrailer.com. Today we're gonna take a look at the PullRite custom installation kit with the base rails for your fifth wheel trailer hitches. And this has a 16,000 pound gross towing weight capacity. Now this is a custom fit part. It is designed to fit the 2016 and newer Ram 1500 trucks with the six and a half foot bed.

And on a custom fit part like this, I do like to recommend for you to go to our website, use the fit guide, put in your year and model vehicle, and it'll show you if this will work for your application. Now this installation kit will let you mount your fifth wheel trailer hitch in the bed of your truck. The mounting brackets, which I've attached to the rails, these will install beneath your truck bed. And they provide the attachment points for the above bed base rails. The base rails right here, these will provide the necessary mounting points for your fifth wheel hitch to mount into.

Now the mounting brackets on the side here, these are custom fit mounting brackets. They mount to existing holes in your vehicle frame. So that'll help minimize drilling and measuring, reduces the installation time and it'll also avoid known obstacles along your truck's frame. One thing I do wanna mention is the best feature on these PullRite brackets are the built-in tabs that are just below the slotted bolt hole. Basically these tabs eliminate one of your biggest problems you'll run into when you install mounting brackets to your vehicle.

Basically this is how to keep those nuts in place when you're installing the bolts of the mounting brackets through here. And I did wanna zoom in just so we can show you a little bit closer to what we're talking about. If I turn this over, you can see where the bolt comes through. So basically if you notice, here's the mounting bracket. So this mounting bracket has this extra tab that's put in there and you see that tab, it is bendable.

So basically what you can do is you can bend this tab down, slide your nut in there, bend your tab back, and then when your bolt comes through. It'll go right into there and you can tighten it down and that tab will hold it in place. So that's a nice feature they thought about because lots of times when you're installing these on vehicles, there's not a lot of room or area to access that to be able to hold those nuts in place. Again, I'll pop up an insert just to show you what we're talking about. There's that underside again, you can see how the nut slides into that opening and that bracket will hold it in place when you put your bolt through. Now this kit is compatible with B&W Patriot, CURT, Demco, Draw-Tite, Hidden Hitch Husky, PullRite and Reese above bed fifth wheel hitches. The finish on these parts, that's nice black powder coated steel, makes it corrosion resistant. And it does include everything shown here, the two base rails, the custom mounting brackets, all the hardware you need for installation, and a real nice set of detailed instructions for installing it. These parts are made in the USA and as we've mentioned, the gross towing weight capacity on this kit is 16,000 pounds. But that's gonna do it for a look at the PullRite custom installation kit with base rails for your fifth wheel trailer hitch.

  • 2025 Ram 1500 5th Wheel Hitch Recommendation
    Hey Jerry, thanks for reaching out! I recommend picking up the PullRite SuperGlide # PUL63RR and pairing it with the PullRite Base Rail Kit # PUL77RR. This kit comes with custom brackets so you aren't drilling into your truck frame, and the hitch is one of the few that have an automatic sliding feature so you can seamlessly take tighter turns without the fear of hitting your truck cab with your 5th wheel. Something else I recommend picking up is the Hopkins Endurance Wiring Kit # 41157...

  • How Does the PullRite OEX SuperLite 5th-Wheel Hitch Install on a 2021 Chevy Silverado 2500
    Hey Oscar, thanks for reaching out! The PullRite OEX SuperLite 5th-Wheel Hitch for Chevy/GM Prep Package # PUL96ZR is designed to fit directly into the puck system on a Chevy/GM truck, like if you had the factory puck system installed on your 2021 Chevy Silverado 2500. If the rails you currently have are adapter rails like the Curt # C88KR, then this PullRite OEX will fit directly to the pucks so you can ditch (or sell, rather) the adapter rails. If you're talking about industry standard...

  • Will the PullRite ISR Series SuperLite 5th Wheel Hitch Fit Industry Standard Rails?
    Hey Mark. I can confirm that the PullRite ISR Series SuperLite 5th Wheel Hitch - 20,000 lbs item # PUL53RR will indeed mount to the PullRite ISR 5th wheel rails you have installed on your 2004 Ram truck. The ISR in both product descriptions stands for Industry Standard Rail so you're good to go. The PullRite ISR Series SuperLite 5th Wheel Hitch item # PUL53RR does not require safety chains. What kind of 5th wheel trailer do you have? You can add this information and any other questions...

  • Could B and W Inverted Gooseneck Hitch Ball and PullRite ISR Series SuperLite 5th Wheel Hitch Work
    Hey Kevin, are you wanting to use the upper ball section of the Pullrite ISR part # PUL53RR with the B&W Turnoverball Adapter # BWGNXA4025 since you don't have much clearance between the ball and your king pin? That would be an interesting setup and in theory it should work but you would have to have a B and W gooseneck ball in your flat bed truck currently which I'd assume you don't since most of them come with their own gooseneck hitch setups. Either way this would be a really clever...

  • Recommended PullRite ISR Series SuperLite 5th Wheel Hitch
    I sure do Paul! The PullRite ISR Series SuperLite 5th Wheel Hitch item # PUL53RR weighs only 52 lbs and has a 20,000 lbs capacity. It'll save you at least 100 lbs depending on which model Husky hitch you have. The included adapter will bolt directly to your trailer's king pin and make connecting quite a bit easier with the funnel design of the base. It sounds like you're using the Adapter Rails item # C29BR that attach to the Ram puck system, so you'll be able to attach the PullRite item...

  • Recommended PullRite Hitch for a 2019 Ram 2500 w/ the Factory Puck System
    Hey Joe thanks for the information! The PullRite ISR Series SuperLite 5th Wheel Hitch item # PUL53RR does not require a gooseneck ball because it attaches to industry standard base rails. Since your Ram truck has the puck system you would need the Adapter Rails item # C29BR to use this hitch. Please note this adapter will raise your hitch height 2-1/2". The PullRite item # PUL53RR does offer a 3-1/2" of offset for additional turning clearance. A way better option since your Ram 2500...

    Hello Adrian, thanks for reaching out. The PullRite 2400 is the ISR series hitch, and yes, this can be used on a 1988 Ford F350 Long Bed Dually. All you will need is an install kit that uses industry standard rails, and for that I recommend the following: - Reese Universal Base Rails and Installation Kit for 5th Wheel Trailer Hitches - 10 Bolt # RP30035

  • How to Install a PullRite 2400 5th Wheel Hitch in the Ford Factory Puck System
    No, it will not Bill but I have a solution for you. To attach your PullRite 2400 5th Wheel Hitch item # PUL53RR to the Ford factory puck system, you'll need the Adapter Rails item # C88KR. There is no replacement base for the PullRite 2400 item # PUL53RR that has the legs for the Ford puck system. The Adapter Rails item # C88KR will drop down into your F-250's pucks and provide a base similar to 5th wheel rails that you'll be able to install your hitch on. What kind of 5th wheel trailer...
