S&S CYCLE 132" Power Package for M8 — 4.5" stroke – 17-25 Trike, 17-23 CVO, 17-24 Touring

Build a high-performance 132" solution for your M8 with a big-bore bolt-in kit that increases 114"/117" engines to 132" without case machining. 🔧

The kit features 4.32" bore cylinders and forged pistons with an 11.0:1 compression ratio, an S&S oil pump and cam plate with a blue anodized finish, removable passage plugs for servicing, and independent scavenge sections for the flywheel cavity and cam chest. 🛠️

Debris screens in both scavenge pickups, a magnet in the cam chest, increased oil flow capacity, and an adjustable pressure relief valve that can be set with the unit installed help ensure reliability. S&S 550 cams, premium tappets, hard-anodized billet tappet cuffs, quickee pushrods, and high-performance valve springs support big-bore applications. Exhaust, cylinder base, and head gaskets are included; intake and rocker gaskets are not. Made in the USA. Not for 121" CVO. 🔩
