We've built and pre-tuned these shocks with damper valving that is engineered for loaded and unloaded payloads. The JBS shock runs at lower pressures than mono-tube shocks, so there is far less energy buildup, a smoother and softer ride, particularly on poor or uneven roads. The simplicity of this design allows for top performance with no external reservoir canisters. This is our approach to all our suspension - simple design with better control both on and off road whether loaded or unloaded.
This front JBS shock let's you chose to keep your factory ride height, or level the front of your F-150 with the removable leveling spacer. This we built from aluminum to resist corrosion.
