Important Notice

The Super 5th is a fixed hitch. On a short bed truck the X-Series coupler's 4" of extra clearance helps, but it's still fixed — confirm your exact truck and bed length in the fitment finder (or with your dealer) before you buy, and expect a wider turning radius than a slider.

Key Features

What Sets It Apart

X-Series base accepts interchangeable couplers — the #4600 is an ISRX base (#4630) plus a Super 5th coupler (#4820), so you can change coupling method later without buying a new hitch
Super 5th coupler is set back to give a full 4" more cab-to-trailer clearance — the room that matters most on a tight short-bed turn
Called the lightest 24K hitch on the market — about 42 lbs to lift once the head is off, roughly two-thirds the lifting weight of comparable 24K hitches
Mounts to PullRite ISR rails or any other industry-standard rail system with no adapters and no tools
King pin height adjusts from 16.25" to 18.75" to level the trailer to your truck
Add the #4424 adapter to convert a gooseneck horse, cargo, or stock trailer into a fifth wheel

About the Super 5th

If you run a long bed truck, you don't need a slider eating up payload and adding moving parts. You have the cab clearance to tow with a fixed hitch, and the Super 5th is built to make the most of it. It's PullRite's fixed-position fifth wheel hitch, made in the USA from high-grade American steel. You can run one on a short bed truck too, as long as your truck and trailer pair up right and you don't mind a wider turning radius to keep the trailer off the cab.

Every Super 5th uses PullRite's patented, fully automatic locking jaw. It's the only self-locking handle on the market, with no secondary lock you have to remember to engage. Back it up, and it latches. The dual-articulating hitch head moves side-to-side and front-to-back, so you can couple and uncouple on uneven ground without jacking or shimming the truck and trailer level first. That same articulation soaks up the bumps and clunks down the road. No false hookups. No high-hooking.

When it's time to pull the hitch, the head comes off with a couple of pins and clips and no tools, dropping the weight you have to lift by yourself. The hitch plate works the same way: pull the pins and clips, lift it out, and take the head weight out of the job. It's a hitch one person can manage instead of fighting it solo or calling for a second set of hands.

Already own a gooseneck horse, cargo, or stock trailer? The #4424 adapter swaps in for your trailer's coupler and converts it to a fifth wheel, so one truck and one Super 5th cover both trailers. And like every PullRite product, the Super 5th is SAE J2638 tested and accurately weight rated, so the number on the label is a number you can actually tow to.

About This Model

The #4600 is the 24K member of the X-Series, rated for trailers up to 24,000 lbs with 6,000 lbs of pin weight. PullRite calls it the lightest 24K hitch on the market, with the head pulled it's about 42 lbs to lift, roughly two-thirds the lifting weight of comparable 24K hitches from other brands. The base bolts to PullRite ISR (Industry Standard Rails) or any other brand of industry-standard rails on tabbed feet, with no adapters and no tools to drop it in or pull it out of the bed.

The X-Series part is what sets this one apart. The #4600 is really an ISRX base (#4630) plus a Super 5th coupler (#4820). If your towing changes down the road, you swap the coupler instead of buying a whole new hitch. The Super 5th coupler also carries a rearward offset that buys you a full 4 inches of extra cab-to-trailer clearance, which is why PullRite calls it a workable second-best option for a short bed when you'd rather not run a slider.

Height sets anywhere from 16.25" to 18.75" at the king pin, so you can level the trailer to the truck. When it's time to pull the hitch the head lifts off on a couple of pins and clips, taking 42 lbs out of the job, though the base itself is still a two-person lift. Assembled, the hitch weighs 136 lbs without the head.
