New Grind for 2021 The Red Shift Cams® RS528 was developed off of the success of the RS527 cam, with a new ramp designed specifically to provide a moderately less aggressive ramp to produce a smoother power curve with an exceptionally quite operation in late model Twin Cam Engines. The power curve characteristics are similar to the RS527

Delivery of smooth and impressive torque and horsepower increases over the factory installed cams are to be expected. This High-Torque cam is designed to get the motorcycle accelerating quicker in the RPM area where most people ride.

Red Shift Cams® RS528 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 part of the secret to the RS527’s tremendous success. This equates to immediate throttle response and acceleration in RPMs earlier than other cams.

  • Use with stock or adjustable pushrods

  • New cam bearings and performance tappets recommended with any cam change.
