Chevrolet Performance 19420455 - LS6 LS9 Valve Spring Kit

The infamous LS6 valve springs were first introduced on 2002 405HP Z06 Corvette to handle the high-revving 5.7L LS engine with a high lift factory camshaft.

The perfect drop-in performance valve spring for most LS applications with a maximum valve lift 0.570".

This spring is the same spec as the commonly used blue LS3/6/9 spring of previous part numbers, but there is a color variation from the manufacturer. Our images have been updated to reflect this change.
