Steel Shock Monotube 7in 4C-6R

The Steel Shock Monotube 7in 4C-6R from AFCO Racing Products is a premium monotube shock absorber engineered for serious off-road, racing, and high-performance vehicle applications where consistent damping and ride control are non-negotiable. Whether you're building a custom 4x4, competition crawler, or performance street rig, this 7-inch monotube shock delivers the reliability and tuning precision that experienced mechanics and fabricators demand. The single-tube design separates the piston rod from the pressure tube, allowing for superior heat dissipation and extended service life under extreme conditions.

The 4C-6R designation indicates a four-way adjustable compression valve and six-way adjustable rebound damping, giving you precise control over how the shock responds to compression and extension cycles. Steel construction provides durability and resistance to impact damage, while the monotube architecture maintains consistent pressure inside the shock body, eliminating the fade and inconsistency common in twin-tube designs. At 7 inches of stroke length, this shock accommodates significant suspension travel, making it ideal for lifted suspensions, long-travel kits, and applications requiring substantial vertical wheel movement without binding or bottoming.

This shock pairs best with custom suspension builds where damping tuning is essential—think rock crawlers, prerunners, ultra4 racers, and dedicated off-road vehicles that see demanding terrain regularly. Installation requires proper suspension geometry knowledge; correct ride height and shock placement ensure optimal performance and prevent premature wear. Mechanics familiar with bypass shocks and adjustable dampening systems will appreciate the straightforward tuning methodology, though detailed setup guides and baseline settings from AFCO are highly recommended for first-time installation to achieve your desired handling characteristics.
