S&S Cycle High Compression 132" / 136" Big Bore Kit For Harley
The biggest just got even badder! These all-new High-Compression 136 and 132 Big-Bore Kits take performance to the next level, delivering harder-hitting torque, increased horsepower, and an aggressive throttle response. With more compression comes more power, giving your ride the punch it needs to dominate the road. These high-compression setups are the largest bolt-on kits S&S has ever sold, and they operate perfectly with standard crankcases, eliminating the need for machining and preserving your original engine serial numbers. The factory-matching powder coat finish keeps your bike looking sleek and covert. These kits also keep the factory engine height for easy installation and include gaskets, making the upgrade process simple. If you want to maximize your machine's potential, the 136 and 132 High-Compression Big-Bore Kits are your ticket to additional power, performance, and excitement. This modification, available in a variety of finishes to match your engine, is designed for riders who will not settle for anything less than the best.
The displacement for these is defined by the stroke. They will only work with H-D's 4-1/2 stroke (114" and 117"), though, in terms of "stock" stroke. To reach 136", you will need to use the S&S 4-5/8" Flywheel Assembly. They will not work with the HD 4-5/8" flywheel.
