Steel Shock Monotube 9in 9C-2R

The Steel Shock Monotube 9in 9C-2R from AFCO Racing Products is engineered for serious drag racing, circle track, and high-performance suspension builds where consistent damping and reliability are non-negotiable. Built for competitors and fabricators who demand precision-tuned shock absorbers that respond identically lap after lap, this monotube design eliminates the variables that plague budget aftermarket options. Whether you're dialing in a purpose-built race car or upgrading a street machine with track-focused geometry, this 9-inch monotube shock delivers the repeatability required to extract maximum performance from your suspension setup.

Monotube construction concentrates the piston rod and working fluid in a single, uncompromised chamber, eliminating external reservoirs and enabling superior heat dissipation during extended track sessions. The 9-inch stroke length accommodates mid-travel applications common in independent front suspension (IFS) and rear coil-over setups on modern chassis, while the steel construction ensures durability under the cyclic loading typical of racing environments. AFCO's 9C-2R designation indicates a purpose-built, street-legal or competition-grade damper with tuning characteristics optimized for vertical load compliance and bump absorption—critical for maintaining tire contact on imperfect road surfaces and bumpy track layouts. Weighing 4.6 pounds with compact cross-section dimensions (3 x 3 inches), this shock integrates into tight packaging scenarios without compromising structural integrity or response characteristics.

Fabricators and suspension tuners select AFCO monotube shocks for bracket-welded or adjustable coil-over installations where predictable damping rates directly influence corner weights and ride frequency. The 28.5-inch overall length accommodates both conventional double-wishbone A-arm geometries and modern independent rear suspensions on platforms ranging from dedicated race cars to restomod muscle cars. Installation requires verification of mounting eye orientation, rod-end thread pitch compatibility, and overall clearance relative to frame rails and surrounding components—work best performed by experienced suspension builders familiar with your specific vehicle platform. Pair with matched front and rear units and quality coil springs to achieve balanced, repeatable handling for road course, autocross, or bracket racing applications.
