We have torcher tested this kit in our YXZ and XX Stage 2 , Outlaw and Big Moe performance engines for several years now. We have run this setup at 40psi boost and up to 12k rpm’s. This kit uses SIT style buckets and custom machined retainers. Great cure for the troublesome problem of losing Exhaust valve locks. But can also be used on the intake side.
Some out of stock parts may ship directly from Manufacturer.
