S&S Cycle 540C Camshaft for Big Bore Milwaukee-Eight Engines - Harley Touring & Softail

The S&S Cycle 540C Camshaft is a performance cam built for big bore V-twin engines of 124cc and larger. Its profile is optimized for maximum low-end torque, delivering usable power below 6000 rpm where riders need it most for acceleration and passing.

Unlike cams designed for peak horsepower, the 540C focuses on torque in the low to mid-range, giving riders stronger pull off the line and instant response when getting on the throttle. It is designed to work with engines of 124cc and larger displacement.

The kit includes the gaskets, bearings, and mounting hardware needed for installation. The cam requires adjustable pushrods and heavy-duty valve springs, which are sold separately, to maintain proper valve train geometry and durability with the 540C profile. It pairs well with the S&S 4.25" Big Bore Kit for riders seeking larger displacement gains.

For off-road / closed-course race use only.
