GILLES TOOLING Axle Nut - Pin-Lock - Rear - M18 x 1.5" ACM-18-15

A secure axle nut is non-negotiable when you're pushing performance limits on the track or street. The GILLES TOOLING pin-lock design uses friction-engaged plastic pins to lock threads with proven reliability, eliminating the risk of fastener loosening under acceleration, braking, and cornering loads. At just 20 grams, this titanium construction delivers safety-critical retention without adding unnecessary rotating mass to your rear axle assembly.

The innovative pin-lock mechanism accommodates standard thread forms and installs like a regular hexagon nut—no special tools required. Beyond rear axles, its multifunctional design also secures pivot shafts and yokes, making it a versatile choice for various bolted joints throughout your build. Engineered from premium Ti-6Al-4V titanium, it pairs seamlessly with the TCA chain adjuster kit for a cohesive, lightweight drivetrain solution.
