Rear Axle Nut RH Discontinued 10/19

The Rear Axle Nut RH by Triple X Race Components is a specialized fastening component engineered for high-performance micro and mini sprint racing applications. Designed with left-hand threading, this aluminum axle nut secures the rear axle assembly on Triple X Micro and Mini chassis, preventing axle drift and maintaining precise wheel alignment during aggressive cornering and acceleration. This discontinued item (production ended October 2019) remains a sought-after OEM replacement for vintage race car restoration and maintenance.

Constructed from lightweight aluminum, this rear axle nut weighs just 0.15 lbs and features a 1-3/4 inch diameter with 27-spline engagement, delivering a secure fit on Triple X Micro and Mini rear axles. The left-hand thread design is critical in racing environments—it provides directional locking that resists vibration-induced loosening during high-speed operation, a common failure point in standard right-hand threaded fasteners. The natural finish preserves material integrity while minimizing corrosion, essential for extended storage and reliability in competitive racing conditions.

Sprint racers, vintage race car builders, and chassis technicians benefit most from having this discontinued OEM component in their rebuild kits. Whether restoring a Triple X Micro or Mini frame or maintaining an existing race vehicle, proper axle nut retention is non-negotiable for safety and performance. Installation is straightforward: thread clockwise (due to left-hand design) onto the 27-spline axle shaft until snug, then secure with a locking mechanism if required by your racing class rules. Stock this item while available, as its discontinuation status makes replacement increasingly difficult.
