OVERVIEW

This HardDrive 39mm Lower Fork Bushing Set provides a direct stock-replacement hardware upgrade designed to restore proper fork action while eliminating slider friction. Precision-manufactured components rebuild worn suspension interfaces, preventing scoring and protecting against premature fork seal failure. Engineered specifically for classic Harley front ends, this chassis solution ensures reliable steering response during routine service or full suspension refresh.

ENGINEERING & PERFORMANCE

These bushings eliminate problematic drag inside the 39mm fork tubes, ensuring smooth vertical travel under load. The Japanese manufacturing process guarantees tight dimensional tolerances that match original equipment geometry without altering ride height or handling characteristics. Built for long-term durability, the components resist everyday wear from highway vibration and aggressive riding. As a straightforward bolt-in replacement, they integrate seamlessly into factory-style rebuilds or aftermarket slider conversions.
