RockJock's Antirock rear sway bar kit for all JK Wrangler Unlimiteds, 4-door), 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, beautiful, fully CNC machined 7075 billet billet aluminum arms, semi-gloss black powder coated bolt-on steel frame brackets, delrin bushings, adjustable length heim jointed sway bar links, long travel stainless braided brake lines that relocate the brake line inboard of the frame for sway bar arm clearance, necessary hardware, and step-by-step instructions. Unit bolts into existing holes in the bottom of the frame rail and attaches to the stock mounts on the vehicle's axle housing. The RockJock Antirock sway bar does not need to be disconnected for off-road use. CAUTION: Jeeps will have more body roll than stock. This sway bar may be used on the street, however, it will not provide the same handling characteristics as the stock setup.

The folks at Core 4X4 are always wonderful to deal with. They explain your options and never pressure or rush things. The quality of the Core Control Arms is top shelf, especially if your goal is to stop wheel hop. I recommend Core 4x4 without reservation ! ! !

These guys are great. You can get them on the phone for support. This important and is not always the case with other custom parts builders. Their control arms are bomb proof and offer plenty of options. You can get real genuine Currie Johnny joints without paying the price for Currie arms.

2001 Wrangler TJ- i have purchased all front/rear upper/lower control arms. Front track bar and rear track bar. Quality is excellent and extremely durable you can tell its built to last. Bent a bolt on the front track bar and called and spoke with Spence. He immediately sent me out new hardware plus some! Product is amazing but what really separates companies apart is their service and these guys are second to none. Thank you all!

Phenomenal company - very rare to come by in the automotive industry. Also very impressing. Let me start here. I got a set of yellow sway bar end links for my 19 ram DT (new body style) and let me tell you, I’m hooked. For numerous reasons. One the craftsmanship behind the product is unmatched for sure for without breaking the bank. 2ndly, they stand behind their product. Had a very minor issue and it was resolved in a blink of an eye!!! Insane. Just because of what i listed above i will forever spend my money with core 4x4! And i think you should too! I have no affiliation at all with this company besides being a consumer. I will be ordering my yellow UCAs and the rest of my rear suspension from them here shortly!
Korby on the other hand. The representative that helped me went above and beyond FAST. I hung up the phone with him, and with in no lie 3 minutes he was calling back with an answer. GREAT GREAT GREAT customer service, Korby you and core 4x4 are what give us hope in the car community! With much love and great health to you all!!
