Your stock harness is punishing your shoulders — and it doesn't have to be. The 50 Caliber Racing 3" 4-Point Harness spreads load across 50% more surface area so you can ride, race, or drive all day without pain. Whether you're in a UTV, a sand rail, a dune buggy, or a truck, this harness fits and performs.

The Last Harness You'll Ever Need — For Any Build

Most harnesses are built narrow and cheap. The 50 Cal 3" harness is built wide, padded, and tough — for serious riders and drivers across every off-road and motorsport application. Pair it with a suspension upgrade or a set of Aces Racing Daytona Seats for a complete cockpit overhaul.

Technical Specifications

Why a 3" Harness Matters for Any Build

Whether you're strapping into a UTV, a sand rail, or a prerunner truck, harness width directly impacts how long you can ride comfortably. Narrow 2" straps concentrate all the load on a small area of your shoulder — after a few hours, that becomes real pain. The 3" design distributes that same force across 50% more surface area, which means less fatigue, better focus, and safer driving. Explore our full suspension and safety collection to build out your complete cockpit setup.

Frequently Asked Questions

Will this harness fit my truck or sand rail — not just a UTV?
Yes. This is a universal 4-point harness. As long as your vehicle has a cage, harness bar, or mounting points for a 4-point system, this harness will work. It's used in UTVs, trucks, sand rails, dune buggies, rock crawlers, and buggies.

Do I need a harness bar to install this?
For most applications, yes — a harness bar or roll cage mounting point is required for the shoulder straps. Check out the Weld-On Harness Tab if you need a mounting solution.

What's the difference between 4-point and 5-point?
A 4-point harness has two shoulder straps and two lap straps. A 5-point adds a crotch strap for additional submarining protection. See the 3" 5-Point Harness if you want the extra strap.

Why choose 3" over 2" straps?
3" straps are 50% wider, which spreads load across more of your shoulder. This dramatically reduces fatigue and pain on long rides or races. If you ride more than an hour at a time, 3" is worth it.

Is this harness SFI rated?
This harness is not SFI rated. If you need SFI certification for sanctioned racing, check out the SFI 16.1 Cam-Lock Harness.

What does the bypass plug do?
It eliminates the seat belt warning beep that some UTVs trigger when you swap to an aftermarket harness. It's an optional add-on — only needed if your vehicle has this warning system.
