Description:

The Kryptonite Stage 3 FOX 2.5 Performance Series Suspension Kit is designed for 2019+ Chevrolet Silverado 1500 and GMC Sierra 1500 owners looking for a premium suspension upgrade that delivers improved ride quality, increased capability, and a leveled stance. Combining FOX 2.5 Performance Series coil-overs, matched FOX rear shocks, and Kryptonite’s heavy-duty boxed upper control arms, this complete system provides the performance and durability needed for daily driving, towing, and off-road adventures.

FOX 2.5 Performance Series coil-overs arrive preset to provide up to 2” of front lift, leveling the vehicle while increasing tire clearance and improving overall appearance. Featuring large-diameter impact-extruded 6061-T6 aluminum shock bodies, these shocks offer increased oil capacity and improved heat dissipation compared to smaller shock designs. FOX’s Internal Floating Piston (IFP) monotube technology separates shock oil from the high-pressure nitrogen charge, reducing aeration and ensuring consistent damping performance in demanding conditions.

Race-developed high-flow pistons and application-specific valving deliver predictable handling, excellent ride quality, and improved vehicle control both on and off the pavement. The larger 2.5” shock body design helps maintain performance during extended use, making this system an excellent choice for trucks that see towing, hauling, and recreational use.

To complement the upgraded FOX suspension, Kryptonite Upper Control Arms are included to maintain proper suspension geometry and ball joint operating angles at the increased ride height. Manufactured from laser-cut steel and robotically welded into a heavy-duty boxed design, these control arms provide the strength, reliability, and serviceability expected from Kryptonite Products.

Whether you’re looking to eliminate factory rake, improve ride quality, increase tire clearance, or enhance your truck’s overall capability, this complete suspension package delivers premium performance, exceptional durability, and clearance for up to a 33” tire.
