    Rated 5 out of 5 by from GM 3/8 Poly locks for roller rockers. I needed a set of 16 poly locks to complete a set on new roller rocker arms that I had previously used the poly locks on another engine. I ordered a set from Jegs and they were here in a couple of days. Good product at a reasonable price, fast shipping.
