Lightest 24K hitch on the market at 94 lbs. X-Series interchangeable coupler with 4" of extra cab clearance for short bed trucks.
The Super 5th is PullRite's proven fixed-position fifth wheel hitch, purpose-built for long bed trucks and drivers who demand maximum towing capacity with no-compromise engineering. Where short bed trucks require a sliding mechanism, long bed trucks have the cab clearance to take full advantage of a fixed hitch — and the Super 5th delivers that advantage with less weight, fewer moving parts, and rock-solid reliability.
At the heart of every Super 5th is PullRite's patented fully automatic locking jaw. It is the only self-locking handle on the market, with no secondary locking devices to manually engage. The precision, laser-cut jaw components rotate around the rearward portion of the trailer's king pin at 140 degrees, creating a tight-fitting 320 degrees of connection. The dual-articulating hitch head moves in four directions — side-to-side and front-to-back — for easier hookup on uneven ground and a smoother ride down the road. No jacking or shimming your truck and trailer to be level with one another. No false hookups or high-hooking.
The hitch head is easily removable with pins and clips, no tools needed, reducing the lifting weight by 40 lbs. or more. The mounting post assemblies are also completely removable — simply unpin the post handles, rotate a quarter turn outward, and lift out. With all four assemblies removed, the hitch sits flat in the bed and can be handled by one person. Premium hardware, including castle nuts for finer adjustment of puck handles, ensures precise installation and a perfect fit every time.
Every Super 5th is SAE J2638 tested, accurately weight rated, and manufactured in the USA from high-quality American steel.
The #4600 ISRX Super 5th is a direct-mount hitch designed for any truck equipped with industry standard rails. Rated at 24,000 lbs. gross trailer weight and 6,000 lbs. pin weight, it is the lightest 24K hitch on the market with a lifting weight of just 94 lbs. with the head removed.
The X-Series platform is what sets this hitch apart: the interchangeable base (#4630) accepts either the Super 5th coupler (#4820) or the SuperLite coupler (#4810). If you prefer a different coupling method down the road, swap the coupler without replacing the entire hitch.
The ISRX design delivers more cab-to-trailer clearance than competing brands, with a full 4 inches of additional rearward offset built into the coupler assembly. That makes it the second-best solution for short bed trucks after a SuperGlide, because every inch of clearance matters during tight turns. Height adjusts from 16.25 to 18.75 inches. No adapters or tools needed to install or remove.
