2019-24 GM 1500 Front Coilover, PS, 2.0, IFP, NON-Trailboss/NOT-AT4 0-2 inch Lift, Trailboss/AT4 NO inch Lift Upgrade the on-road comfort and off-road control of your 2019-2024 Chevy Silverado or GMC Sierra 1500 to FOX Performance Series 2.0 Coil-Over IFP (internal floating piston) shocks. The mono-tube design's internal reservoir separates the shock oil from the high-pressure, nitrogen-charged gas chamber. The IFP eliminates oil aeration allowing maximum performance from the factory-tuned, precision valving. Locking, spring preload rings that allow easy ride height and preload adjustment retain a top-quality racing coil, selected to deliver the optimal spring rate. FOX shocks bolt on with no modifications and are designed to level your truck front-to-rear. The metal impact-extruded aluminum body increases cooling capacity and resists rust. Vehicle-specific upper mount includes a composite bushing that isolates noise and vibration. Fox and BDS joined forces to custom valve each application to work perfectly with each BDS Suspension system. The basic shock design is based on Fox Racing Shox race products, but re-designed to turn your BDS equipped truck or Jeep into an offroad machine. Cold-forged, metal-impacted 6061 T6 aluminum shock body dissipates heat three times faster than a conventional steel body shock. The 2.0 Performance Series shock runs as cool as a 2.5 diameter shock on the same application. Heavy-duty 5/8 chrome shafts are induction case hardened to over 55 Rockwell C, virtually eliminating scratches caused by rust and debris. The Internal Floating Piston (IFP) design separates shock oil from the high pressure nitrogen charged gas chamber, eliminating oil aeration and cavatation, while providing a predictable ride — capable of handling the roughest conditions with fade-free performance.
