Alum C/O Sleeve 7in Fox

The Alum C/O Sleeve 7in Fox from ALLSTAR PERFORMANCE is a precision coil-over sleeve engineered for high-performance suspension tuning on Fox shock systems. This component serves as the interface between your coil spring and shock absorber, enabling adjustable ride height and spring preload configuration essential for track vehicles, street rods, and performance cars demanding suspension customization. Whether you're fine-tuning corner weights or optimizing spring rates for specific driving conditions, this aluminum sleeve provides the structural foundation for reliable coil-over assembly.

Machined from aluminum and finished with black anodizing, the Alum C/O Sleeve 7in Fox accommodates a 2.5-inch inside diameter spring and works with 2-inch shock diameters typical of Fox shock absorbers. The seven-inch length provides adequate travel range while maintaining compact packaging, and the threaded design allows repeatable adjustment without slipping or settling. Black anodized finish resists corrosion and provides a professional appearance while protecting against oxidation in harsh under-car environments. The lightweight aluminum construction reduces unsprung weight compared to steel alternatives, contributing to improved suspension responsiveness and handling dynamics.

This sleeve is ideal for builders and enthusiasts working with Fox shocks on independent front or rear suspensions where coil-spring configurations are preferred over traditional leaf springs. Installation requires proper alignment with your shock body and spring stack to ensure smooth operation throughout the suspension travel range. The threaded collar system enables quick adjustments between shop sessions or competitive events, making it invaluable for race teams needing rapid suspension geometry changes. Verify your shock diameter and spring dimensions match the specifications before ordering to ensure proper fit and function.
