S&S CYCLE 132" Power Package Engine Performance Kit — bore 4.320", 11.0:1 compression, gear cam drive – 17-25 Touring, 17-26 Trike

The Power Package bolt-on engine performance kit increases displacement without case machining and retains stock engine height and original serial numbers.

Big-bore cylinder architecture pairs forged pistons with a multi-layer steel head gasket to deliver durable, high-performance combustion.

The oil pump and cam plate feature removable passage plugs for serviceability, independent scavenge sections for the flywheel cavity and cam chest, debris screens in both scavenge pickups, a magnet in the cam chest to trap debris, and increased oil flow capacity on feed and scavenge sides.

An adjustable pressure relief valve is accessible with the unit installed, and the valvetrain uses quickee pushrods with pushrod tubes, premium tappets, and hard-anodized, black-coated billet aluminum tappet cuffs for long life.

High-performance valve springs accommodate cams to high lifts, while the conical single-wire spring design and performance cam profiles are optimized for big-bore applications.

The kit includes a cam cover badge, is made in the USA, works with stock crankcases, retains original engine serial numbers, and is compatible with stock valve springs of both first- and second-generation designs.
