Product Details

Fabtech's 4" Performance system features four heavy wall tubular lower link arms with rotational urethane pivot assemblies on each end that provides articulation like a heim end but without the noisy highway ride. System includes billet transfer case spacers, pitman arm, rear sway bar links, bump stops, rear trac bar bracket and front sway bar disconnect links. For maximum articulation add the optional upper links. Extended length coil springs provide clearance for 33/12.50R15 tires.

    Fabtech Performance Shocks have been designed to work in conjunction with each of our suspension systems, resulting in superior ride control. Features include high velocity 9-stage valving for excellent dampening capabilities and a closed cell insert to reduce shock fade at high speeds.

    Rear Performance Monotube Shocks

    Fabtech's Monotube Shock Absorbers feature high pressure nitrogen gas that reduces fade during aggressive offroad driving. The Monotube design allows for a larger piston compared to twin tube shocks with greater cooling efficiencies due to the single wall seamless tubing. An internal free floating dividing piston separates the nitrogen gas from fluid to eliminate foaming and shock fade. Each shock has been pretuned specifically for the vehicle application providing a superior ride quality.
