The S&S Cycle Winter Power Package returns after a two-year hiatus, offering a big bump in performance for Harley-Davidson Big Twins at a discount for a limited time. The Milwaukee-Eight packages are available in 124ci and 128ci big-bore kits with a 550 cam, cam plate, and high-flow oil pump, as well as valve springs, lifters, and pushrods. The Twin Cam kits get a similar combination of performance parts with a 585 cam and a bump to 100ci for the early TC motors and 110ci for later models. All kits are available with gear or chain drive cams and are designed to reliably provide significant boosts in power. Winter-only pricing starts at $2,299, a cost saving of more than $400 when ordered now through January 31, 2023. Check out the details, parts list, and dyno charts at S&S Cycle’s website.
