The PRP 5.2 Latch & Link Harness Ratchet (SFI 16.1) is a 5-point racing harness built around PRP's Latch & Link buckle system, with 2" shoulder belts, 2" lap belts, and a 5th-point anti-submarine strap that runs between your legs to keep you from sliding under the lap belt in a hard stop. What sets this model apart from the standard 5.2 Latch & Link harness is the integrated ratcheting lap belt system: instead of pulling a webbing tail through a cam buckle to tighten the lap belts, you crank a ratchet mechanism built into each lap belt to dial in exact, repeatable tension every time you strap in. That matters more than it sounds. A harness that's slightly loose on the lap belts loses a lot of its restraint value in a rollover or hard impact, and a ratchet system removes the guesswork of whether you pulled it tight enough.
The shoulder belts use PRP's upgraded EZ adjusters, so shortening or lengthening them is a one-hand motion instead of fighting a stiff cam buckle, and the shoulder pads are removable, letting you run the harness with or without a HANS-style neck restraint depending on what your event or seat setup requires. The 5th-point strap is also removable and has its own adjuster, so it can be lengthened, shortened, or taken off entirely if your cage or seat mounting doesn't call for a true 5-point layout.
On the hardware side, this harness uses bolt-in mounting tabs as the standard configuration, with clip-in tabs available separately from PRP if your car uses eyebolts instead of bolted mounting points. The shoulder belts are wrap-around compatible using 3-bar slides, so they work whether you're bolting to a fixed point or wrapping around a roll cage bar. Hook-and-loop strap keepers keep the excess webbing from flapping around or getting caught on something mid-race, and built-in loops for a communication line or hydration tube mean you're not zip-tying accessories to the harness after the fact.
This harness carries SFI 16.1 certification, the spec most off-road racing sanctioning bodies (and many track day and closed-course events) require for a 5-point restraint system. That means it's built and tested to a defined standard, not just marketed as "racing" without the paperwork behind it.
If you're deciding between PRP's harness options, this Latch & Link Ratchet model sits between the standard 5.2 Latch & Link with removable pads, which uses a simpler pull-up lap belt without the ratchet mechanism, and PRP's Cam-Lock line, which swaps the Latch & Link buckle for a twist-and-thumb-release Cam-Lock buckle with CleanLatch dust sealing. PRP also offers a Cam-Lock version with the same ratcheting lap belt for drivers who prefer that buckle style. Choosing between them mostly comes down to buckle preference and whether you want the fine-tuned tensioning this ratchet system gives you over the standard pull-up design.
What's included: two ratcheting lap belts, two shoulder belts with EZ adjusters, a removable 5th-point strap with its own adjuster, removable shoulder pads, and the mounting hardware for a bolt-in installation.
