Specifically designed for Harley models, this gas-charged steel shock absorber kit offers a robust and economical solution to replace or upgrade the rear suspension. Its compact body with internal reservoir maintains the classic aesthetic while providing a 5-position cam preload adjustment to quickly adapt the firmness according to rider, passenger, or load.

Several style options are available (full show-chrome or black covers). Note: on some Harleys (notably the XL '86-'15), installation may require modifying or spacing the chain/belt guard to ensure proper clearance. A shock absorber that is slightly longer or shorter than the original may alter the rake angle and steering responsiveness. Check the clearances between the swingarm/exhaust and chain/guard before installation.

Common applications: ideal for Vintage/Classic and Touring, compatible with many Dyna and Touring models. Ref. 412-4048C.
