Z20 Timing belt kit with 2 uprated idlers

Performance Cam Belt Kit

This uprated cambelt kit is built upon the Z20LEH kit, that includes one uprated steel idle roller on the exhaust side. It fits all the variants of Z20, the LET, LEH, LEL and LER.

We have replaced the intake side plastic roller with another uprated steel one. We find that the plastic rollers tend to make the belt degrade very quickly, along with themselves, which can be seen by pick up on both the roller and the belt after not too much running time.

With these steel rollers you do not get this pick up, and the rollers themselves will stand up to a lot more high rev abuse than their plastic counterparts.

We fit this kit to every engine we build now, as the more we looked at the rapid belt degredation, the more it worried us!

All parts are genuine GM, but we include a better bolt and lock washer for the tensioner, which doesn't have the silly shallow drive like the original.
