Improve the driving experience of your Gladiator JT with Fox 2.0 Performance Series IFP shock absorbers. Made in the USA, Fox 2.0 Performance Series shocks feature lightweight aluminum bodies and mono-tube valving. The IFP feature stands for Internal Floating Piston. IFP completely isolates the gas charge from the shock fluid to eliminate the possibility of aerating the fluid. This is a common problem with cheap twin-tube shocks where the gas charge is stored in a plastic bag that can quickly deteriorate. Not a problem with Fox Performance Series. In addition to separating the gas charge from the shock oil, IFP adds a measure of ride quality since the floating piston adds "cushion" during compression. The lightweight aluminum body also dissipates heat better than steel shocks. On or off-road, you'll be thrilled with the quality, performance, and ride of your Wrangler with Fox shocks. JKS is here to help you choose the right type and length shock for your Jeep. No one knows better than JKS.
