This kit has been one of our top-secret in house valve train upgrades for a long time and we feel its time to release it to the public.

We see way too many people drop shims and retaining clips causing a valve to drop destroying their motor. 

This kit is one of the most important upgrades you can do to a YXZ motor and we have put it to the test so you don't have too.

We have ran this kit at over 45 pounds of boost and up to 30 pounds of boost on anti-lag.

Includes:

  • Heavy duty shim under buckets
  • Turbo springs
  • Spring bases
  • Custom CNC machined retaining caps
