Star P38 Lightning 615 Twin Cam Camshaft — .615 Lift
The next step up from the legendary Torkstar 577 — higher lift, broader application, and built for Twin Cam engines that are ready to perform.
Part Description
The Star P38 Lightning is the natural progression for riders who want a step up from the Torkstar 577 and are ready for more. Designed for chain-drive 2007-and-up Twin Cam engines, the P38 delivers .615" lift across a wide range of displacement combinations — from 103 cubic inch all the way up to 117 cubic inch piston kit builds. Whether you're running a mild street build or a serious big-bore kit, the P38 Lightning is engineered to extract strong, reliable performance from your Twin Cam engine. Before installation, verify that your existing valve springs are rated to handle up to .620" lift — spring capability is the key installation consideration for this cam. Recommended install with Star 655 Lift Spring Kit (TC20-20350).
