JKS Mfg adds specially tuned FOX 2.0 Adventure Series IFP Gas Shocks to lineup for Jeep Wrangler JL. Designed for improved damper performance in rough terrain and all around comfort and control, thee shocks take advantage of FOX's racing pedigree and offering an affordable option that packs true race proven capability. They feature a monotube design and an internal floating piston (IFP) to separate the shock oil from the high-pressure, nitrogen-charged gas chamber, preventing oil aeration for fade-free performance in rough terrain. Lengths and shock tuning have been specially designed for the JKS lift kits to optimize performance. Get more out of your lifted Jeep JL FOX Adventure Series 2.0 shocks.
