Zipper’s Red Shift 657 Cams Chain Driven
Fitment: The Zipper’s Red Shift 657 Cams for 2007-2016 Harley FLH/FLT Touring Models, 2009-2016 Tri-Glides and 2007-2017 Softail and Dynas
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. Zipper’s Red Shift 657 Cams can also be used in 2006 FXD engines
657-HS: The Zipper’s Red Shift 657 Cams are an extremely popular grind for 110” and larger modified engines. Max early torque with balanced power for quick acceleration with a heavy payload. Narrower timing increases compression for more low-mid grunt, with excellent peak power. Excellent valve train dynamics for long life, works well with most bagger exhaust.
Recommended: Use with Red Shift® Dual Piston Cam Chain Tensioners (#413-901) for improved cam chest component reliability, maximum throttle response and reduced valve train noise. As well as reduced valve train noise. These cams require adjustable pushrods.
