Overlanders and Racers! RockJock heard you and the wait is over! Their heavy rear bar Antirock Sway Bar Kit for the rear of all JT Gladiator models features a 1 1/8 in. diameter, 28 spline bar! This heavier bar considerably increases the rate of the rear sway bar for those with racks, roof top tents, camping gear, etc. The bar is also applicable to desert racing applications. When used in conjunction with a front Antirock sway bar kit, provides balanced performance of front and rear suspension for rugged off-road conditions. It gives the driver increased traction by balancing and distributing the weight and traction over all four tires. The Antirock off road sway bar is designed to directly replace the stock Jeep sway bar. This bar is made of SAE 4130 heat treated steel for ultimate strength, which is the same quality used in professional off-road competition sway bars. This kit includes all components for installation including, the sway bar, semi-gloss black powder coated bolt-on steel frame brackets, delron frame bushings, semi-gloss black powder coated forged 4140 chromoly arms, adjustable length heim jointed sway bar links, necessary hardware and step-by-step instructions. Unit mounts into a holes in the frame behind the axle and attaches to the vehicle's stock axle housing. The RockJock Antirock sway bar does not need to be disconnected for off-road use.

Recieved warrenty exchanges for my control arms last night couldnt be happier!!! Lets talk about the arms tho! Great quality arms in multiple styles and colors!!! I purchased the teir 3 short arns for my 98 xj. I can say that they setoff nicely so my 35 inch tires do not rub! As long as you can get a photo or video of broken hardware core will take care of you. The body of the arm is bulletproof. However make sure to maintain and grease the joints regularly as with any greaseable joint and they shouldkast forever. I had a few problems arise a year after purchase and after some troubleshooting spence was able to help get me the correct parts to get back on the road. I recommend this setup to any and all jeepers looking to get away from the stock arm setup. Alltogether i am Very happy with the performace of my control arms!!!! Mechanic and bodyman of 12 years and my first choice for quality control arms!!

Ive had the front adjustable control arm kit in bright green for my 1996 ZJ.
Ive had the kit for about a year now and i have to say, im extremely impressed, over 1000 miles off-road and roughly 20,000 miles on the highway. These control arm kits for any vehicle built by core 4x4 are well worth the money, just be aware thereight be some minor scatches or chips from shipping ( but who should care about that if you're beating the crap out of em' they way they were built and designed for)
