525-HS:Extremely popular Early (High)-Torque for 96” and 103” Twin Cam® engines with stock, unmodified heads.
Perfect for 96” and 103” 2007-Up Touring models, this cam was developed to deliver immediate passing power in 6th gear at any typical cruising speed.

Red Shift® Performance Cams for 2007-Up* Twin Cam Engines
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

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.

Mountains? Passengers? Heavy Trikes? No Problem! Red Shift® 525 cams are the perfect Touring model cams. These cams take a stock 96” or 103” engine and turn it into an extremely fun to ride, quick to accelerate performance machine. Red Shift® 525 cams are the industry’s most powerful bolt-in cam for engines with unmodified heads. No more upshift-downshift to get over a hill, just put the bike in 6th gear and turn the throttle to get power when you need it!

Recommended: Use with Red Shift® Dual Piston Cam Chain Tensioners for improved cam chest component reliability, maximum throttle response, and reduced valve train noise.
