S&S CYCLE 129" Power Package — 129 in, 4.32 in, 11.0:1 – 18-26 Softail, 24-26 Touring, 17-26 Trike, 25 CVO

Build more displacement from the 107" M8 platform with this bolt-on power package. It increases displacement to 129" without case machining, making it a direct path to a bigger setup.

The kit combines 4.32" bore cylinders and 11.0:1 forged pistons with S&S oiling components, including a cam plate and oil pump with removable passage plugs, independent scavenge sections, debris screens in both pickups, and a cam-chest magnet to help keep debris out of the oil pump.

It also includes Quickee pushrods, S&S premium tappets, hard-anodized black coated billet aluminum tappet cuffs, S&S 550 cams, and valve springs designed for cams up to 0.605" lift. Compatible with VVT models.

Note: Not for Trike models. Intake/rocker cover gaskets are not included.

Made in the USA.
