Adam E was very helpful. He had information that help confirm the correct part numbers. His response with processing the purchase was quick. Will order again soon.


Been working great as it should! Good adjustability. Thanks!


It's heavy duty!


This solved my problem. The Reese hitch bar that came with my load distribution hitch did not have the holes I needed to have my travel trailer line up with my ball mount. I used C17100 in the up position and I needed the holes near the bend to have my truck ball one inch higher than my trailer coupler. With the hitch bar that came with the 6000 lb Reese , in the up position and the lowest setting my ball was 4 inches higher than coupler. In the down position my ball was lower than my coupler.


I have the Pro Series Weight Distribution System w Friction Sway Control - Round - 10,000 lbs GTW, 1,000 lbs TW product PS49903. I pull a 5000# haulmark race trailer 24' with my 2012 ram 1500. I got the weight distribution system and it was great, but according to the instructions, I could not get my hitch ball to 21" at the lowest. So the ride has been ok but I id prefer the ball to be at 21", currently at 22" so I ordered this shank. It has the lowest holes that I could find, however only appears to drop the ball about 1/2". Probably not worth it for 1/2", but I care a lot about my cargo so I thought I would give it a shot. Mind you I have not installed it yet, just put it up next to my current shank and it looks like it would drop the ball1/2"


Quick shipping on an item that was exactly as described.


The product appears to be exactly what I needed. It arrived yesterday and I will switch out from my old hitch shank tomorrow. My old part was used on a taller truck that I traded off and just made the hitch ball too low. This product is definitely heavy duty. Thank you


I needed a different rise Shank for my new RV than the one I had and the Curt 8" fell perfectly into the range I needed.

The shank is solid steel and heavy and the holes look to be precision machined. Welds look hand done as there is a little sloppiness with some of them but nothing structurally detracting.

You can use this shank in the up or down position so the description that only gives a small amount of drop or rise is a bit misleading. Just know that the max dimension will work for the up or down position.

Powder coating looks good but I do't expect it to last as most of the paint on these things get scratched up in use.


I have not received the shank yet, it is at the border. When I pick up my shank and equalizer hitch and have it set up I will gladly review both products.


Very happy with all products purchased for this set up. Dealt with Crystal ( aka CK!). She was extremely knowledgeable on all our product needs. She kept me as a customer and resolved some issues I was having with a prior purpose. Great product and great job to Crystal.

Thank you


Product was exactly as advertised and delivered very quickly. I needed something that would allow adjustments on my hitch and this fits perfectly.


Exactly what I needed.


Just what the 'doctor' ordered ... Fits well, gives me the adjust-ability to allow use on several different vehicles ... Good quality materials ...


Got exactly what I ordered! Fast shipping and the website is easy to navigate. With my new truck the old shank even with a shim was sloppy fitting. This one is made for my 2019 and sits nice.


Perfect height adjustability for my stock, not lifted 2017 Tundra.
And if I do a conservative 4" lift on 33" tires...The hitch Will still work


I am very very pleased with it I like the way the quality is on it it looks very heavy duty to pair to my old one


Good product, worked as intended. Would purchase again without question


Well put together. Heavy duty product d elivers.


I was very pleased with the ordering process; I was notified when the order was received and when the product was shipped. The product was received in great condition and was exactly what I ordered.


Product works well.... well built


It fit perfect No complaints



Just what I needed. Excellent turnaround. Good price. Thanks.


Product as described and on time

  • Will the Curt Adjustable Weight Distribution Shank Accept 3/4 Inch Diameter Bolts
    I spoke with my contact at Curt and the Bolt-Together Adjustable Weight Distribution Shank - 12 Inch, # C17100, does take 3/4 inch diameter mounting bolts. The measurement between the bolt holes from center to center is 1-1/4 inches. I have attached a photo of these measurements that may help out.

  • Comparing Forged and Welded Weight Distribution Shanks
    There are not many differences between a welded and forged weight distribution shank in regards to practicality. They both pass the same DOT standards and meet the maximum 15,000 lb weight capacity requirement. The forged shanks started to become popular to save weight with 2-1/2" hitch applications. I would be willing to bet the receiver tube on your motorhome is a 2" therefore you would be best to just stick with a welded shank. I recommend the Curt Adjustable Weight Distribution Shank...

  • Will Curt Weight Distribution Shank # C17100 Fit Curt Weight Distribution
    The Curt shank part # C17100 that you referenced might be slightly different from what came on your system, but it's the same in the areas that matter. The vertical portion of the shank and the mounting holes are the same size so the head of your system will easily fit on this shank and work well. The holes are 1-1/4 inches apart and 3/4 inch in diameter.

  • Recommended Weight Distribution System with 5 Inch Rise for 2007 Toyota Sienna
    For your weight distribution system, the rise is due to the shank itself. Most weight distribution shanks are able to be interchanged between manufacturers. For your application, I recommend the Curt Adjustable Weight Distribution Shank - 8" # C17100. This will give you up to a 6-1/2 inch rise using trunnion bars or up to a 7-1/2 inch rise using round bars. You will simply invert the shank to give you the height needed. To give you the correct system for your application, I need to...

  • Replacement Shank For Curt Weight Distribution System Round Bar C17002
    I confirmed with my contact at Curt that the correct replacement shank for Curt Weight Distribution System C17002 is Curt Adjustable Weight Distribution Shank # C17100. This offers 7 adjustment holes and measures 8" from the center of the pin hole to the center of the adjustment holes. I have attached a demonstration video for this shank.

  • Recommended Weight Distribution Shank for Low Ground Clearance
    It sounds like you're looking for a new weight distribution shank with less drop and if that's the case we have tons of great options. In order to see how much drop/rise you need you can measure from the ground to the top inside edge of the trailer hitch and then subtract the distance from the ground to the bottom of the trailer coupler while level. I have attached a full list of our options below. The Curt Adjustable Weight Distribution Shank part # C17100 for example only offers a 2"...

  • Distance From End to Hitch Pin and Overall Length of C17100
    From the pin hole to the end of the shank of the # C17100 measures 3 inches and then overall length would be 12 inches. 3 inches is a very common dimension for the pin hole but it's not totally uncommon to see 4 inches.

  • Is Curt Weight Distribution System Available With 12 Inch Adjustable shank
    The Curt Weight Distribution System With Sway Control, part # C17322, has a 10000 lb gross towing weight and is designed to fit 2 inch by 2 inch receiver openings. It comes with a shank that has a 5-1/2 inch rise or 7-1/2 inch drop opening. If you wish to need the Curt Bolt-Together Adjustable Shank, part # C17100, it would have to be purchased separately.

  • Which Weight Distribution Shank for 24 Inch Receiver Height and 17 Inch Coupler Height
    Ideally, you'll want your weight distribution head to sit about 3/4 to 1-1/2 inches higher than the level coupler height of the trailer to compensate for trailer squat. Since the difference in your coupler and receiver height is 7 inches, I'd recommend you go with a shank that offers at least a 6 inch drop, like the Curt # C17121. This would put your trailer ball about 1 inch above level, which would be absolutely perfect.

  • Weight Distribution Shank for Curt System and 2-1/2" Receiver on a 2018 Ford F-250
    We actually do have a variety of WD shanks that will work with your Curt WD system and the 2-1/2" receiver on your 2018 Ford F-250. I recommend the Curt # C17131 because of how close it is to the size of the Curt # C17100 that you referenced. I have attached a link to our selection of WD shanks that are compatible with 2-1/2" receivers for you to check out as well. These actually all have the same dimensions and hole sizes for the adjustable bolt holes so most shanks are interchangeable...

  • Are Bolts Included With the Replacement Head for Curt MV Weight Distribution Systems Part # C17075
    The Replacement Head for Curt MV Weight Distribution Systems part # C17075 does not come with the bolts that you will need to attach it to the Curt Adjustable Weight Distribution Shank part # C17100. For this, you would also need the Replacement Bolt Kit for Curt MV Weight Distribution Systems part # C17076.

  • Availability of Weight Distribution Shank that Fits 2-1/2 inch Hitch Size
    We have weight distribution shanks that fit the 2-1/2 inch hitch size like what you have on your 2019 Ram 2500 like with the Curt # C17132 if you need a lot of drop or the # C17131 which doesn't give quite as much drop.

  • Why is the Maximum Drop on the Curt Adjustable Weight Distribution Shank # C17100 2-1/2 Inches?
    The reason why the Curt Adjustable Weight Distribution Shank # C17100 lists the maximum drop at 3 inches is because the maximum measurement in the drop position from the inside top edge of the receiver tip of your hitch to the top of the ball of a compatible Curt round bar systems like the Curt MV Weight Distribution System w/ Friction Sway Control # C17063 is 3 inches. I went ahead and linked a video from the Curt # C17063 that talks about this maximum drop measurement in addition to the...

  • How To Transfer Weight Distribution System From a Truck To An SUV With Different Ground Clearances
    I do have the correct options for you but the Roadmaster High-Low Adapter part # RM-076 cannot be used with a weight distribution system. Since you have two vehicles with very different ground clearances you will just need to have two shanks, one for the truck with more drop and one for the SUV with less drop. The good news is that most weight distribution shanks are pretty universal so all I would need from you is the drop needed for each vehicle. This can be found by subtracting the distance...

  • Troubleshooting Height Adjustment for Reese Weight Distribution System
    The Reese Weight Distribution System w Shank - Round Bar - 6,000 lbs GTW, 600 lbs TW # RE34FR is 49911 you referenced. It definitely doesn't sound right that there is more than 4 inches of difference from the base of the hitch ball when inverting your weight distribution shank with closest settings. I'm attaching an article to assist. If you need something that allows more of that middle adjustment, I recommend the Curt Adjustable Weight Distribution Shank - 8" # C17100.

  • Recommendation for Adding 2nd Friction Sway Control Bar to Trailer
    To add a second friction sway control, you will need the second Reese Friction Sway Control Kit # 83660 and you'll need to weld a tab onto your trailer hitch ball platform like # C45822. The friction bar will simply be inverted on the left side, but that will not impact the function and is designed for use on either side. I've attached an article to assist and 2 bars are recommended on trailers over 26 feet long or if you simply want more sway control. The other option is to use a weight...

  • Shank with More Drop for Blue Ox Weight Distribution System # BLU45FR
    The shank that comes with Blue Ox weight distribution system # BLU45FR has a drop of 1-1/2 inches so for a shank that has 3 inches of drop you can use # C17100. But you may want to go with something that offers more rise/drop options just in case you need it in the future. For that I recommend # 17120. For a round bar weight distribution system it offers up to 6-1/8 inches of drop and up to 10 inches of rise. Both shanks listed above are compatible with your weight distribution system.

  • Will Curt Weight Distribution Shank Work in Place of Equal-i-zer Shank for 2 Inch Receiver
    Weight distribution shanks are one of the few parts that are okay to swap between brands and still work; since both shanks fit in a 2" hitch receiver you can use the Curt Adjustable Weight Distribution Shank # C17100. We do carry the Equal-i-zer shank you are looking for though if you would like to use that, the Equal-i-zer Weight Distribution Shank # EQ90-02-4100.

  • Availability of 16K Weight Distribution System with Adjustable Shank that Has 12 Inch Drop
    We do not have any round bar weight distribution systems available that are rated for the amount of weight you are looking for so you will need to go with a trunnion bar setup. For this I recommend taking a look at the Reese Strait-Line Weight Distribution System # RP66130. This system features a towing weight capacity of 15,000 pounds and a tongue weight range of 800 to 1,500 pounds. You will want to make sure the total tongue weight of your setup (which includes both the loaded tongue...

  • Ball Mount to Tow Trailer With Clevis Hitch
    We do have some options for you to tow a trailer with a clevis mount but the Buyers Products Adjustable Tri-Ball Mount # 3371802225 that you referenced doesn't have provisions for that. Instead you can either use the Convert-A-Ball # CAB-6W which comes with 3 different hitch ball sizes plus the clevis or the Curt # C45008 which has 2 hitch balls and the clevis but you need a shank like part # C17100 to mount it to for adjustability.

  • Weight Distribution Recommendation for Work and Play 21VFB Toy Hauler
    Nearly all weight distribution shanks were made to the same dimensions. Shanks like the Curt part # C17100 fit nearly all brands of weight distribution heads. As long as the holes of your old shank are 3/4 inch in diameter and are spaced 1-1/4 inches apart the Curt shank you mentioned will fit. The best way to pick out a weight distribution system is to base it off of the loaded tongue weight of the setup when it is loaded and ready to tow. This figure also includes the weight of any cargo...
