RockJock offers forged chromoly arms for Antirock sway bar kits as an upgrade to existing vehicles or for those looking for maximum strength for their rock crawling rig! These arms provide maximum strength and rigidity via their forged 4340 chromoly construction and I-beam cross section design. Arms are 3/4 in. thick, 16.2 in. long overall, making them 14.2 in. from center to center, to outer hole. The vertical offset design of these unique arms allows for maximum suspension uptravel in applications that feature clearance restrictions. These arms feature 2 adjustable sway bar link mounting holes and they can be used in conjunction with our RJ-201000-101 Double Sheer End Link Bracket Kit. These arms would be replacements for our Jeep JT Gladiator heavy bar rear Antirock kits that feature the 25 spline torsion bar. Sold as a pair only.

Great company, who worked with me on shipping parts to arrive in time for a show. When I explained my concern they went above and beyond to make it happen. Quality of the parts is top notch.

I have nothing but good things to say about Core 4x4. I have the crawler series on my JKU and we take it all over the place. These parts handle everything we throw at them.

Best control arms I have installed on any of my builds. After running every major manufacturer, Core 4x4 is on par or better than all the high-end companies at a fraction of the cost. Lifetime warranty is the cherry on top.

Installed the full kit on my XJ. Ride quality is night and day better than what I had before. The articulation on the trail is insane. These guys know what they are doing. Already recommended Core 4x4 to everyone in my club.

I have nothing but great things to say about this company and their customer service. If you like American made products backed by warranty and amazing customer support, this is the company for you. I have a Lexus GX470 and love their rear control arms.

Great product, excellent customer service. I mistakingly ordered a track bar for the wrong year model and Korby helped me out by sending me the correct part that I needed no questions asked. I highly recommend.

Small business, family owned, made in the USA, lifetime warranty. Purchased Tier 3 control arms and rear track bar for a 2006 Jeep LJ. Simple website and easy to contact over phone and email. I had some technical questions and they were happy to answer them. They allow local pickup and were built to order same week. The order was wrapped and ready when I walked in and even gave a tour of the shop. They abrasive blast all raw materials to achieve a better surface profile for powdercoat to adhere and create a smooth, durable finish. I also noticed several CNC machines and a robotic welder they use for all their parts. A small outfit with a robotic welder? Their concern for quality is obvious and it shows in the parts they make. Very impressed. Happy to do business with these guys.
