Description
Upgrade your vintage suspension package while maintaining absolute factory heritage with this brand-new Genuine OEM Harley-Davidson Performance Rear Shock Spring Kit. Manufactured in Japan during the peak of the Evolution engine era, this high-performance kit features a matching pair of heavy-duty, shot-peened gloss black coil springs designed to deliver a firmer rate, reducing rear-end sag and improving cornering stability. The kit is completely untouched and brand new, preserving both coil springs inside their factory-sealed protective plastic wrappers. It comes complete with a sealed hardware installation pack containing performance spring collars and clips, alongside the original factory instruction sheet.
