Quick Overview

If you're looking for top of the line products for your Jeep Wrangler JK Unlimited and outstanding performance, consider the J-VENTURE 3.5" lift kit made by JKS Manufacturing. This lift kit is designed to perform equally on-road with equal off-road capability. It includes the essential elements without over-complicating the system.


The dual rated coil springs are designed to provide the best ride and performance in any situation – street riding, trailing, rock crawling, loaded down or running light. The Fox 2.0 Adventure Series shocks are well known for high performance due to the internal floating piston design that prevents fade. These Fox shocks are a perfect match for these high performance coil springs.


The JKS adjustable track bar is vastly superior to the factory track bar, dwarfing it in size and performance. It is adjustable to compensate for the lifted coil springs and includes factory type rubber bushing. Specs include 1-1/4” threaded adjustable end for fine tuning and superior strength that is combined with the 1-1/2” x 3/8” wall DOM tube, CNC formed track bar. This option is far superior to track bar relocation brackets for greater handling and to keep bump steer to a minimum.


JKS was the originator for the sway bar disconnect. These Quicker Disconnects have adjustable lengths, include the JKS poly-flex ball, high mis-alignment ends, stainless steel mounting studs and are greasable. For Rubicon owners, hardware is included to bolt the Quicker Disconnect links to the axle and sway bar, thereby eliminating the disconnecting pins while keeping the other benefits of the Rubicon disconnecting sway bar.


JKS does not consider brake line relocation as an option and includes brackets in this kit. These brackets are designed specifically to work with the Fox shock lengths with just enough length at full axle droop and minimal modification to the factory routing. JKS includes their 3/16” heavy duty steel rear track bar bracket that will relocate the rear track bar and brace it directly to the axle tube thereby reinforcing the factory bracket. Also included are front 2-3/4” billet aluminum and rear steel bump stop spacers that fasten directly to the axle to provide safe compression limits for both the coil springs and Fox 2.0 shocks.
