If JKS designed the factory JL Wrangler suspension, this is how it would be done! Introducing the JKS 1.5" J-Spec Suspension System with your choise of specially tuned FOX 2.0 IFP Adventure Series, FOX 2.0 IFP Performance Series, FOX 2.5 IFP Peformance Series, or FOX 2.5 Performance Elite Series shocks. Whether your focus is improving on-road characteristics or suspension performance in the backcountry, this system has been carefully engineered to excel in a variety of terrain while providing clearance for up to 35" tires. The JKS dual rate coil springs are a tried and true design that provides excellent versatility - on-road comfort is provided by the softer rate, while the firmer rate increases capacity for your gear and improved control off-road. All springs are scragged to eliminate settling after install and shot-peened to add more surface area, significantly increasing long term durability. The springs have a longer free length, creating a low-lift height system with excellent wheel travel when you need it during off-road expeditions. The FOX 2.5 IFP Performance Series shocks have been tuned side-by-side these dual rate springs to create a complete fine-tuned package. Tuned specifically for optimum ride and performance on plus-sized wheel and tire packages, these shocks feature the same high-quality aluminum bodies and internal floating piston architecture used in FOX Performance Series 2.0 shocks, now in a new 2.5-inch diameter body. The larger diameter valve shims translate to a smoother feel - think firmness without harshness, allowing for a softer tune. 50% more piston surface area provides less damping fade and more bottom-out control at higher speeds, increasing on and off-road control. Paired with JKS dual rate springs, this shock and spring combo creates control and comfort even with moderate increases in weight, giving you the freedom to loadout your vehicle with the gear you need. Additional weight may affect net ride height - for very heavy vehic
