  • Pro X High Compression Piston Kit

    Pro X High Compression Piston Kit

    Ryan in PA

    No instructions

    This piston worked great but it comes with a copper/gold looking ring and a black ring and didnt say what ring goes where, the copper/gold closest to the top of the piston then black then the small one then the wrinkle oil ring then the other thin silver ring was so hard to figure out which on went where. Other than that, great product

    Excellent product as expected from hinson

    I have been running a Hinson basket for the last four years. Last year I added the inner hub and other components and it is working flawlessly.

  • Hinson Hi-Temp Clutch Spring Kit

    Hinson Hi-Temp Clutch Spring Kit

    Jess in OH

    Not sure on longevity yet, but no fade!

    Not sure how long they last, but I had a slow speed high temp ride with two on my quad pulling another quad with two after riding all day and not one time did it slip. Climbs hills like a champ again and no slowing or slipping toward the end of the day. Also the clutch pull didn't seem to change at all even though the springs were definitely stiffer and longer than the stockers.
