RockJock's Billet Aluminum Antirock Sway Bar Arms are beautifully constructed, yet offer race quality strength for aggressive off road applications! Made entirely in house on their own machines, they start with premium 7075T6 aluminum material, CNC machine the arms to shape, CNC machine the pocketed design and the logo etchings, broach the 25 splines and finish them off in clear anodizing! These specific arms are 15 in. long from tip to tip, 3/4 in. thick and feature a 2 1/2 in. offset bend to provide clearance in applications where it’s needed. At the arm mounting end, you’ll find RockJock's standard 25 spline that fits all common Antirock torsion bars as well as our high-end, 12-point vertical pinch bolt and nut. RockJock's billet aluminum finishing washers and flat head allen bolts that thread into the end of the sway bar torsion bar are also included. At the end link mounting end, the arms trim down to 3/8 in. thick and you’ll find two 1/2 in. Sway Bar End Link mounting holes that allow you to adjust end link mounting position to increase or decrease leverage on the torsion bar. These 2 holes are commonly used in conjunction with RockJock's RJ-201000-101 Double Sheer End Link Bracket Kit.

Awesome product and service! I even got some of their swag because it looked pretty darn good. I will definitely be going back and would suggest this business to others looking for quality control arms. Buy local!

Awesome control arms! My mechanic said “ your Jeep is pretty much bulletproof now.” And I just got the tier 1 arms! The people at the core 4x4 shop were really nice too. They were running behind on shipping, (which is understandable) so I decided to go pick it up because it was only an hour drive. They gave me a free $60 hardware kit for the inconvenience. Thanks core 4x4! You guys are awesome!!

First of I just want to say Great customer service korby Has helped me from the start and has not let me down! Reached out to him again today and he was able to warranty some parts out for me.
As far as the quality of the parts.. excellent! The build quality is great. I can definitely tell a
Difference from the cheap oem rear control arms to these and the pan hard bar.
Color, From what I can tell it’s super durable been through a few mud holes on top of the daily road grime and after a quick wipe they still pop!
Overall I recommend. Customer service is everything for me and it’s definitely there at Core 4x4.

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 ! ! !

First off, I wish I knew about them sooner. The customer service is top tier. The response time is about 30 min no waiting 1-3 days to get a response. The parts are heavy-duty and look amazing. The packaging is perfect, I can't wait to hit some trails. Thanks Core4x4

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!
