3 S&S Cycle Power Upgrades for Your Vtwin

Power Aid

Why, yes, S&S Cycle DOES make performance parts for Milwaukee-Eights (of course; they’re S&S, after all). Seeing as how they’ve been squeezing the most out of American V-twins since 1957, this is a surprise to no one. That said, we thought you M8 and 2019 XL owners would like a little more info on a few of the more popular upgrades they have for you and your ride.

The company’s Hooligan Kit still includes 482 cams, premium tappets and all of their XL kits are available in 1200cc or 1250cc. Look for a $200+ savings over previous kits and kits are available for most 1986-2019 XL models.

Matched to the billet aluminum S&S cam plate and you’ve created a great combination of oil management parts in your Milwaukee-Eight powered touring or Softail model.

ABOUT S&S Cycle®

What started as a passion for speed, grew into the best known company name in the V-Twin high performance aftermarket. George J. Smith had to build his own parts to make his motorcycle faster. Now the company he founded manufactures the most pretigious line of "go fast" v-twin engine parts in the world. The company was started in the basement of his home in Blue Island IL in 1958, and moved to Viola, WI in 1969. In 2004 an additional facility was opened in La Crosse, WI.
