Important Notice

How much slide your truck needs depends on its bed length, so confirm the 20K SuperGlide fits your exact truck and bed with our fitment finder (or your dealer) before you buy. A Capture Plate (sold separately) is required to drive the slide and must match your trailer's king pin setup.

Requires a Quick Connect Capture Plate

This hitch requires a capture plate matched to your trailer's king pin box, sold separately. You must select the correct capture plate for your specific trailer brand.

About the SuperGlide

Short bed trucks gave you back garage space and a smaller turning radius, but they cost you something behind the cab: room to turn a fifth wheel. Crank the wheel hard and the trailer's nose swings right toward your rear window. The SuperGlide fixes that without asking anything of you. It's a fully automatic sliding fifth wheel hitch, and it works while you drive.

Here's what makes it different. As you turn or back up, a patented cam action moves the trailer away from the cab along the hitch, then slides it back to the towing position over your axle the moment you straighten out. That gives you a full 90 degrees of turning. No levers to throw, no switches, no climbing in and out of the truck before and after every turn the way a manual slider demands. You just get in and drive.

Every SuperGlide is built around PullRite's patented, fully automatic locking jaw — the only self-locking handle on the market, with no secondary lock to reach over the bedside and engage by hand. The hitch head moves side-to-side and front-to-back, so you ride smoother over rough roads and can couple and uncouple on uneven ground without jacking or shimming to get level. When it's time to clear the bed, the head pulls out on a couple of pins and clips. No tools, and a lot less weight to wrestle. A Capture Plate, sold separately, mounts to your trailer's skid plate and is required to drive the slide.

It's also SAE J2638 tested (the recognized fifth wheel strength standard) and accurately weight rated, so the number on the label is the number you can trust. Every one is made in the USA from American steel. Want to pull a gooseneck trailer too? The SuperGlide works with PullRite's #4424 Horse Trailer Adapter to convert a gooseneck coupler to a fifth wheel.

About This Model

The 20K sits in the middle of the SuperGlide family. It's rated for trailers up to 20,000 lbs gross trailer weight (GTW = the loaded weight of the trailer) with 5,000 lbs of pin weight, so it covers the larger fifth wheels that outgrow the 16K without jumping to the heaviest build. PullRite uses heavier steel in the head and the cam arm here than on the 16K, so the parts that do the work hold up to the extra torque a bigger trailer puts on them through every turn.

It mounts to PullRite Industry Standard Rails (ISR) or any other industry-standard rail system. If you already run rails, you can pull your old fifth wheel and set the 20K right onto them. Slide travel is fixed at 14", and the right amount of slide depends on your truck's bed length, so run your truck through the fitment finder (or ask your dealer) to confirm the 20K is the correct SuperGlide before you buy.

When it's time to clear the bed, the head lifts off on a couple of pins and clips and takes 43 lbs off the job. The base that stays behind is still a two-person lift, so plan on a hand.
