BTR LS Rockers & Valvetrain

Brian Tooley Racing LS rocker and valvetrain hardware including LS3 shaft rockers, trunnion upgrades, dual valve springs and chromoly pushrods.

Confirm cylinder-head family, rocker geometry, spring load, pushrod length and intended camshaft before ordering. Built by Boost & Tune can assist with complete valvetrain specification and workshop installation.

Choose the right valvetrain component

The BTR LS3 shaft rocker kit and BTR V2 trunnion upgrade kit serve different rocker arrangements. Check the individual listing before choosing a complete rocker system or an upgrade for compatible existing rocker arms.

Review the BTR Platinum LS dual spring kit against your camshaft and cylinder-head requirements. The listed 7.400-inch BTR chromoly pushrods require the correct measured pushrod length for your assembly.

Planning a camshaft change? Compare BTR LS camshafts and cam kits and check kit contents before adding individual springs or pushrods.
