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...

  • 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 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...

  • Can Pullrite 2400 ISR Hitch Be Used On 1988 Ford F350 Long Bed Dually?
    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
