Red Shift 525 Cams have a unique design feature which produces an extremely fast and turbulent inlet charge in the combustion chamber at low RPMs. Inducing turbulence in the chamber as early as possible is the secret to the 525’s tremendous results. This equates to immediate throttle response and acceleration in RPMs, lower than ever before possible on a stock 2007-up Twin Cam® engine.

The stroked crankshaft in the 96” engine changes the dynamic from 2006 and earlier model 88” engines, making correct cam choice crucial to avoid engine damaging detonation with today’s fuel quality. Spring work required unless otherwise noted as a bolt-in cam. We recommend new cam bearings and performance tappets with any cam change. *These cams can also be used in 2006 FXD engines
