The NEW HRSS Clutch kit for the 2016 Tundra Extreme 800ETEC or Renegade setup for utility work, heavy towing or just plain trail riding. The factory clutching is beyond way off causing overheating sheaves, blown belts, and terrible performance. We developed a kit that engages smooth, increases fuel mileage, keeps clutch temperature down, and keeps the $169.00 belts happy. It has been tested from pulling groomers and tow sleds to just plain old trail riding. Top speed increases over 10mph because the clutches aren't fighting each other. The kit includes primary spring, secondary spring, helix, HRSS2 ramps, and oversize rollers. We encourage you to change your QRS rollers also when you install your helix and spring. Our kit utilizes the stock 18.8 gram pins. Please note the pic above is not what comes in the kit---we don't have a picture yet. Complete installation instructions included.
