Available in both 2.5 Inch and 3.5 Inch lift variants, all 8 of the adjustable control arms included in our Premum 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.

The 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 Gladiator 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 Inch x 5/16 Inch DOM tubing. This extra thick tubing gives us a thicker wall diameter and is especially important around the adjustable johnny joint adjuster.
This JT 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/JT 2.5 Inch and 3.5 Inch 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, or in the JT's case a triple rate coil due to the additional cargo area and weight. 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.
Sway Bar Links: Proper sway bar angles result in better handling and increase off-road performance. The more you lift your vehicle, the more necessary proper sway bar angles become. On road this will help to control body roll, and off-road a longer sway bar link will make sure your link doesn't act as a limiting strap.
Our links are 100 percent bolt in, and no cutting and drilling are required. End links are pre-greased and have Teflon coated heim joints, simple, easy and effective.
Bump Stops: Bump stops are another simple yet effective component used to limit up travel either before your tire runs out of room, or your shock runs out of travel. The front bump stops are 3 1/4 Inch tall made from UHMW and can be cut if you want to customize your up travel.
Rear bump stops are powder coated and are 3 Inch tall steel spacers, with pre-drilled holes for optional bolt-on spacers for those of you looking to customize your rear up travel. Both front and rear bump stops utilize a simple bolt on installation.
Our attention to detail, matched with high quality made-in-the-USA parts, means that our customers are getting the Ultimate Jeep Suspensions available.
