SuperTech Cam Follower Shim

Price: $4.23 (USD)
Supertech 1JZ/2JZ 8mm Shim. These are for Supertech shim-under cam followers (buckets) for JZ engines. You use them in conjunction with shim-under buckets to adjust the valve clearances, the buckets are sold separately. This setup is lighter weight and allows much higher RPM with big cams. These are easier to set up than shimless buckets, and you can go thicker and thinner than the shimless buckets would allow.
