Coil Nut Alum.

The Coil Nut Alum. is a precision-engineered adjuster nut designed for coil-over suspension systems, specifically engineered to work with 2.5-inch ID springs. This aluminum component serves as the critical interface between your coil-over spring and adjustment mechanism, enabling fine-tuned ride height and spring preload adjustments on performance and off-road vehicles. Built for those who demand reliability in their suspension setup, this universal adjuster nut accommodates a wide range of coil-over applications across different platforms.

Manufactured from aluminum and finished in a durable gold anodized coating, the Coil Nut Alum. combines lightweight strength with corrosion resistance—critical for suspension components exposed to road salt, moisture, and thermal cycling. The gold anodized finish provides both functional protection and visual consistency with premium coil-over kits. The anodized layer creates a hard, wear-resistant surface that maintains its appearance while resisting oxidation, ensuring consistent thread engagement and repeatability through countless adjustment cycles. At 0.28 lbs, this lightweight component contributes minimal unsprung weight while maintaining the rigidity necessary for reliable suspension tuning.

This adjuster nut is essential for builders and enthusiasts working on coil-over suspension kits where height and preload adjustment is required. It fits 2.5-inch ID coil-over springs and threads onto standard adjuster bodies, making it compatible across most universal coil-over systems. Whether you're dialing in a lowered street car, a track-focused platform, or an off-road build, this aluminum nut allows smooth, repeatable adjustments without galling or binding. Installation requires no special tools beyond standard wrenches, and the universal design ensures compatibility across diverse vehicle applications where precision suspension tuning is paramount.
