Available in both 2.5" & 3.5" lift variants, all 8 of the adjustable control arms included in our Premium kits feature our dual durometer Giiro Joint bushings and forged Johnny Joint adjusters. These narrow series forged Johnny Joint adjusters feature a greaseable, and rebuildable 1 piece bushing capable of up to 40 degrees of misalignment. The Giiro joints are free pivoting, self-lubricating, self-centering, silent in operation and maintenance free bushings that make our kits ride like butter no matter what's underneath your vehicle. If that all sounds like it's too good to be true, that's because it should be - but the structured anatomy of our Giiro bushings matched with their superior material formulation allows two distant worlds to meet as one, providing you the desirable comfort of a daily driver and then easily transitioning to meet the extreme demands of rugged off-road terrain.
Gas engine JL's can expect to gain about 1/2" more lift than advertised, 4xE model JL's will gain advertised height.
*2-door Jeeps may receive slightly more lift than advertised due to differences in vehicle weight

Some Specifics:
CONTROL ARMS : Setting proper axle position, pinion angles and caster angles is critical to delivering a smooth on road ride, great off-road flex and overall performance. When everything is adjusted properly your vehicle just works better, not only day one, but also for years and years to come. Our control arms feature a unique bushing which utilizes a large outside knurled washer to allow greater surface area and therefore a superior clamping force. Proper clamping force is critical in eliminating death wobble issues and overall handling. Lower control arm housings also use a super thick 5/16s housing to eliminate the worry of denting or ripping the housing apart. A premium tube insert is pressed into the alternate end, plug welded and then fully robotic welded for maximum penetration, consistency and precision. Premium arms feature narrow series forged Johnny Joint adjusters which are greaseable, and rebuildable. They use a 1 piece bushing capable of up to 40 degrees of misalignment ready to tackle any terrain.
TRACK BARS : Setting a proper vehicle track is also very important for handling and on-road performance. Our track bars are constructed using 1 3/8” x 5/16” DOM tubing. This extra thick tubing gives us a thicker wall diameter and is especially important around the adjustable johnny joint adjuster. This JL specific rod end gives us an easy bolt in design, is easily adjustable, and specifically designed with a longer body to provide greater access to the jam nut. The frame end uses a dual durometer free pivoting, self-lubricating, self-centering, silent in operation and maintenance free bushing GIIRO joint to help with road noise isolation.
COIL SPRINGS : Linear rate, dual rate, triple rate, what do you really need? We actually use all 3 variants depending on the vehicle, height and capacity requirements. Linear coils have a single spring rate and are evenly spaced top to bottom which makes for a great spring for most applications. The main advantage being that the coils don’t touch each other, which can lead to wear and tear and coil failure. The dual rate coil has a tight set of coils usually at the top, and then a second set of coils with more traditional spacing below. Dual rate coils do not ride any better than single rate coils despite popular belief. The first rate is usually completely compressed and acts as a spacer, its purpose is to provide a longer free length coil so at maximum articulation the coil doesn’t unseat. In most applications, including the front of our JL 2.5” and 3.5” lift kits the coils do not unseat and there is a top post and bottom bump stop present so coils cannot fall out even at max articulation. But in the rear, there is no coil post or lower internal retainer, and therefore a dual rate coil is necessary. All of our coils are powder coated black using a new SealKor finish which is a zinc rich powder coat to help in the prevention of rust and corrosion.
