TeraFlex partnered with FOX Factory to create a long-travel performance shock absorber with proprietary TeraFlex valving to handle the demands of a Prerunner setup – resulting in the lightweight aluminum bodied FOX Factory Performance Series 2.0 Reservoir Smooth Body Shock. 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 and TeraFlex Jeep-specific valving matched to the coil springs in our suspension systems Performance Series 2.0 Reservoir Shocks provide a predictable ride quality capable of handling the toughest terrain. Our proprietary FOX valving codes in these Prerunner shocks are only available through TeraFlex or one of our authorized dealers.
