// WHY THIS PART EARNS ITS SPOT
Bump Stop Spacers - Proper bump stop extensions are a must and our heavy-duty kits stand up to hard use while keeping the tires off of the shiny new JL fenders! The front bump stops in this kit are unique to the 392 Hemi vehicles.
Johnny Joint Trac Bars - Heavy duty adjustable length Trac Bars included are our forged chromoly, organically shaped front bar, and our Chromoly rear bar. Our Trac Bars combine a precise fit with increased strength and adjustable length to perfectly center front and rear axles under the vehicle. High-articulation Johnny Joint ends provide maximum durability and suspension flex.
// THE FULL RUNDOWN
RockJock's Pro Edition Johnny Joint Suspension System for JL Wrangler Unlimiteds with the 392 Hemi engine provides 3 1/2 inches of lift and allows for efficient clearance of up to 37 in. tall tires (larger tires will require aftermarket fenders and minor trimming). This kit is comprised of only the highest-end components in the areas of strength, fit, finish, function, and the engineering to back them, delivering a smooth, comfortable on-road ride with the ultimate in-off-road capability – all in a complete, direct bolt-on kit. This kit is designed specifically for the serious off-roader who not only wants to lift their vehicle and install big tires but also wants to tackle the toughest trails in the country with confidence and ease.
Premium shock packages from Bilstein, Fox, and King are offered here as options so that you can select the shock brand and performance level that matches your driving style. We always recommend adjustable shocks, as they allow the rider to be tuned to match the terrain and driver’s preference.
