Features to know about

Built for Confident Heavy Towing: 20,000 lbs GTW and 5,000 lbs Vertical Load Limit

This SuperLite 5th wheel hitch is rated for 20,000 lbs gross towing weight with a 5,000 lbs vertical load limit, giving you the strength and control needed for large fifth wheels. The black powder coated steel construction resists corrosion and keeps the hitch solid and secure over time. It’s tested to SAE J2638 standards, so it’s ready for serious towing miles.

Hook Up the Easy Way: Funnel-Style Hitch Head and Ball Adapter

Getting lined up is simple with the open funnel on the hitch head that guides the ball right in. The included coupler bolts around your trailer’s king pin to create a clean connection point that drops into place smoothly. You can see the funnel easily from the cab during hookup, which makes solo connections faster and less stressful.

Clearance Where You Need It: 3-1/2" Extra Cab Space and Adjustable Height

The hitch adds 3-1/2" of extra cab clearance to help with tight turns or changes in terrain. Adjustable height from 15-3/4" to 18-3/4" lets you dial in your setup for a level trailer position and proper bed rail clearance. This flexibility helps balance your load for stable towing on long trips.

Lightweight Two-Piece Design for Quick Removal

When you’re done towing, you can free up your truck bed fast. The hitch weighs just 84 lbs and separates into two pieces that lift out easily from the above-bed rails. No extra tools or equipment needed—just pop it out to get your full bed space back for everyday hauling.

Video Transcript for Review of PullRite 5th Wheel Hitch Rails - Custom Installation Kit - PUL59RR

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. It has a 20,000 pound gross towing weight capacity. Now, this is a custom fit part. It is designed to fit the 2020 and newer Chevrolet Silverado and GMC Sierra 2500 and 3500 trucks with the 6-3/4 foot bed and without the OEM prep package. 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, the installation kit here will let you mount your fifth wheel trailer hitch into the bed of your truck. The mounting brackets, which I've installed here on the sides, these mounting brackets install beneath your truck bed. And they provide the attachment points for these above bed base rails. The base rails, both of these here, provide the necessary mounting points for your fifth wheel hitch to attach to. Now, the custom fit mounting brackets, these are designed to mount to existing holes in your vehicle's frame to help minimize drilling and measuring, reduces installation time, and it'll even help avoid known obstacles along your truck's frame.

Now, one of the best features on these PullRite brackets are the built-in tabs. That'll be just below, they're on the top of the mounting brackets just below these bolts on each corner. And I want to zoom in and show you where they're located. It's hard to see them because they're underneath, but they're right in here. And what's nice about those tabs, they eliminate one of your biggest problems when installing mounting brackets to your vehicle, which is how to keep the nuts in place when installing the bolts of the mounting brackets.

And basically what they look like, if I pop up this insert, that's the underside, you'll see that tab there. It's a thinner metal. You'll be able to bend that down, slide the nut in there, and then when you put your bolt in, tighten it down, that tab with the slot in it will hold the nut in place. So it allows you to tighten your bolt down without having to access underneath there 'cause usually the problem on most when you install them, like I mentioned, is accessing that nut and bolt to tighten it all down. This makes it a lot easier because once you put that nut in there, all you have to worry about is tightening that bolt down.

Now, this kit is compatible with PullRite, B&W Patriot, the CURT, the Demco, the Draw-Tite, Hidden Hitch Husky, and even the Reese above-bed fifth wheel hitches. They do use a black powder coat steel, which is corrosion resistant. Does come with the two base rails, the custom mounting brackets, all the hardware you need for installation, and a nice set of detailed installation instructions on how it all goes together. These parts are made in the USA. And again, the gross towing weight capacity is 20,000 pounds. But that should do it for a look at the PullRite custom installation kit with these base rails for your fifth wheel trailer hitches.

  • Do A 2022 Chevy 2500 And A 2026 Chevy 2500 Use The Same 5th Wheel Hitch Installation Kit?
    Hey Jesse, cool name! You can actually re use your hardware, brackets and rails here. The 2022 Chevy 2500 and the 2026 Chevy 2500 use the exact same custom brackets and hardware. So, assuming your new truck does not have the factory puck system, and assuming you can remove everything cleanly, you can absolutely use the same installation kit on your new truck. If your new 2026 Silverado has the factory fifth-wheel puck system, let me know because that changes the setup. Or, if you want...

  • Can I Re-Use Hardware For Pull Rite 5th Wheel Rail Kit On Silverado?
    Hey there Don. While you may be able to do that, it's not recommended as the hardware on the 5th wheel rail kit is supposed to be 1-time use only. When torqued down, the threads get stretched and will not be the same strength after removing and trying to install again. I recommend grabbing another 4 bolts (5/8-11 X 3” HEX BOLT GR 5) and 4 new nuts to go with it ( 5/8”-11 SERRATED FLANGE NUT ZIN) - you should be able to source them at a local hardware store. They don't offer a hardware...

    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.

  • 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...

It'll save you at least 100 lbs depending on which model Husky hitch you have.

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...

    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...
