Alum Shock Threaded Body 9in

The Alum Shock Threaded Body 9in from AFCO Racing Products is a precision damping component engineered for high-performance suspension tuning and racing applications. Built for enthusiasts and competitors who demand predictable, repeatable shock performance across diverse track conditions, this threaded-body shock absorber delivers the adjustability and durability required in circle-track racing, road course competition, and serious street-performance builds. Whether you're fine-tuning your car's handling balance or transitioning between different racing venues, a quality shock body forms the foundation of responsive suspension geometry.

Constructed from lightweight aluminum, this 9-inch shock body reduces unsprung mass compared to steel alternatives, improving acceleration response and wheel compliance over bumps and road imperfections. The threaded design allows seamless cartridge or internal component exchange without removing the entire shock from your vehicle, simplifying maintenance and tuning iterations in the shop or paddock. AFCO's manufacturing standards ensure consistent bore tolerances and valve seat integrity, critical for maintaining consistent damping rates lap after lap. At 4.9 lbs and measuring 17.55 inches in length, this shock integrates into compact engine bays and tight suspension geometries while maintaining adequate ride height and travel range for medium-duty applications.

This threaded-body shock suits both double-adjustable and single-adjustable setups, making it ideal for bracket racers, amateur road-course competitors, and weekend track-day drivers optimizing suspension compliance without full component replacement. Installation requires compatible shock mounts and spring perches matched to your suspension geometry; verify tower height and eyelet spacing against your vehicle's current suspension layout before ordering. Pair with valved cartridges and spring rates matched to your vehicle weight, track surface, and driving style for maximum handling stability and tire contact.
