Description
If you’re running a Twin Cam engine and chasing consistent power delivery, timing chain lash is costing you precision and headroom for aggressive cam profiles. The S&S Cycle Cam Kit with 4 gears eliminates the play inherent in stock chain drives, locking in accurate valve timing while the gear-driven design reverses rear cam rotation—opening up clearance for higher lift cams and stronger mid-range performance. This is a serious upgrade for builders and racers who demand reliability and repeatability.
Installation requires professional-level expertise and equipment; this is not a bolt-on job. You’ll need a hydraulic press and fabrication knowledge to machine the inner gear cover and properly seat the components. Plan accordingly and consider professional installation to ensure proper fitment and longevity.
