Made in the USA, this shock absorber integrates particularly well into the Vintage/Classic, Roadster, and Touring categories. Before installation, check the clearances and wheel travel; on some XL models ('86-'15) it may be necessary to adjust or space the chain/belt guard. Also note that a shock absorber that is slightly longer or shorter than the original may alter the rake angle and steering responsiveness.

Common application examples: Harley-Davidson Electra Glide (FLHTI, FLHTCUI) and Screamin' Eagle (FLHTCSE2). For regular heavy-duty use, consult the recommended Heavy Duty options.
