Drag Specialties Fork Tube Damper Mount Kit Screws with Washers Replaces Harley 45405-75A

OVERVIEW

The Drag Specialties Fork Tube Damper Mount Kit provides a direct hardware solution to maintain and restore proper front-end damping on Harley-Davidson motorcycles. Designed to replace factory-mounted fasteners, this kit secures the damper tubes while preserving fork alignment and ride stability. Constructed with durable steel bolts and copper washers, it is engineered specifically for Harley-Davidson Softail, Sportster, Dyna, and select Touring platforms.

ENGINEERING & PERFORMANCE

This mounting kit stabilizes the internal damper rod assembly within the lower fork legs, preventing unwanted axial movement and high-frequency vibration during normal operations. The included socket-head bolts feature a corrosion-resistant black finish, while the copper washers ensure precise torque retention without galling the aluminum fork slider surfaces. Built to meet or exceed OEM dimensional tolerances, the hardware maintains consistent clamping pressure, which is essential for predictable suspension response and long-term fatigue resistance.

WHY HARLEY RIDERS CHOOSE THIS

Riders and independent mechanics prefer this mounting kit because it restores factory-correct fork geometry without requiring specialized tools or aftermarket adapter plates. The dual-material design pairs impact-resistant steel fasteners with copper washers to hold tension precisely where damper tube pressure demands it, eliminating play that typically causes vague steering feedback. Drop-in installation preserves the original mounting pattern, making routine fork maintenance straightforward and reducing shop labor time. By addressing weak points before they affect handling, this hardware keeps vintage and modern Harley frames tracking straight and absorbing trail imperfections reliably.
