Product Overview

TeraFlex partnered with Fox Racing Shox to create a long-travel performance shock absorber with a lightweight aluminum body, while the proprietary TeraFlex valving handles the demands of a prerunner setup - resulting in the Fox Racing Shox 2.0 Performance Series Reservoir Shock Absorber w/ CD (Compression Damping) Adjuster. The 8-click CD Adjuster tunes the compression damping from very soft to very firm.

Testing with the Fox development team in the southern California desert resulted in one the most performance-oriented race-ready shocks available for its time. Our proprietary valving combined with data from on-site tuning and extensive driver feedback data resulted in a shock that can handle some of the toughest and fastest trails out there.

With its race developed high-flow damping piston matched to the TeraFlex Jeep-specific valving, the 2.0 Performance Series Reservoir Shocks provide a predictable ride quality capable of handling the roughest terrain.

TeraFlex-tuned Fox Racing Shox are matched to the TeraFlex suspension systems. Our proprietary Fox valving codes in these prerunner shocks are only available through TeraFlex or one of our Authorized Dealers.
