Being bolt-in Cams, they are fully compatible with stock pushrods and valve springs. That equates to an economical installation, since there is no need to invest in those replacement parts. In addition, the savings in labor is substantial, since the cylinder heads do not have to be removed to install valve springs.
The 482 cams work well for stock 883cc and 1200cc engines, and they are ideal for the S&S 883 to 1200cc conversion kits. The best performance gains are from 3500 to 6500 rpm. Although the 482 cams are designed for 2000 and later engines, they can be installed in 1988-’99 engines with stock flywheels if a 2000-up pinion gear is used. MSRP 299.95.

This dyno chart from the Dynojet® 250i chassis dynamometer shows the performance of the S&S 482 cams compared to stock cams in 1200cc Harley-Davidson® Sportster models. In both tests the bike had an S&S Stealth air cleaner and a S&S Slip-on Performance Mufflers installed. The S&S 482 cams provided almost 5 more horsepower and 2 ft-lb of torque.
