Brian Tooley Racing makes some of the most powerful camshafts on the market for LS and LT engines. We are proud to announce that we have paired up with BTR to bring our customers some of his most popular camshafts & spring designs.


SK001 springs are designed for use with stock rockers.

Heavier roller rockers require more spring pressure to maintain control of the valve train.

We recommend our SP002/SK002 for roller rocker applications.

Note: This kit will not fit LS9 engines, please see item SK006 for LS9 heads.
