Make it yours with a custom 5-point Harness! Choose from the options below and build the perfect SFI Certified Racing Harness for your ride.


  • Bolt in Tabs – The traditional tabs found on most harnesses. Can be bolted to the appropriate mounting location in your vehicle.
  • Clip-in Tabs – Make it quicker and easier to remove the harness for cleaning, or to access a battery. All the tabs on these harnesses can be removed and switched out with Clip in Tabs, you just need to purchase them separately here.


  • Roller Adjuster – The traditional lap belt adjuster found on most harnesses. Can sometimes be difficult to use if it gets dirty.
  • EZ-Adjuster – PRP’s new and improved style of the adjuster. The EZs allow you to easily tighten and loosen the belts, even if they are dirty or muddy. These come standard on all the shoulder belts, but now you can add them onto the lap belts as well!
  • Pull-up EZ Adjuster – Rather than the traditional pull-down lap belts, with these belts you pull the straps up towards your chest making it easier to get the belts extra tight if there’s not a lot of room in the cab. The 3 bar adjusters on each end allow you to change the spacing of the EZ Adjusters to account for larger or small riders.
  • Ratchet Adjuster – Gets your lap belts as tight as possible! Great for those who are racing at high speeds. Mount the ratchet mechanism side of the lap belt next to the door, and your crew can tighten it down with the supplied ratchet.

Shoulder Pads

  • Removable Shoulder Pads– Having this feature allows for versatility when you want comfort or when racing. Keeps the pads on for recreational driving to protect your neck from chafing against the belts. When racing – simply remove the pads and the straps can be secured into your HANS neck restraint device. This Custom 5-point Harness is perfect for any setup!

SFI 16.1 certified for racing.
