RockJock's Rear Shock Relocator Kit for JK Wranglers and Unlimiteds is designed for use when a JK is lifted and a high-articulation suspension system, such as the RockJock Johnny Joint Suspension System is installed. Upon dramatic articulation of the suspension, the shocks are able to make contact with the side of the chassis. This can cause bending or breakage of the shocks. By tipping the bottom of the shocks outward, they are given the little extra clearance they need to not contact the chassis. Again, this applies to suspension systems such as our bolt-on kit that features 4 standard length control arms mounted in stock chassis and differential brackets. This information and these components may or may not apply to any given long arm/long travel and triangulated suspension systems. For use with factory differential housings only. Finish on all components is zinc plating.

Top notch company. Mechanic lost bolts that clamp upper control arms. Korby sent out spare bolts no charge. Best customer service I’ve come across in a long time. Only suspension brand I’ll ever use.

To start off if you're looking to upgrade your control arms definitely hit this company up. Great product, easy install of the product, with three different tiers everything is priced pretty good, I'm a sticker guy and they sent a sticker for each arm each track bar and also three extra ones so the extra are on the Jeep the advertise them for sure. If you're reading this review I highly recommend you to check their website out.

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 ! ! !

Great customer service. I got my front upper and lower control arms and hardware on Friday afternoon. It didn’t come with instructions so I called Core 4X4 and they immediately e mailed me the instructions. Also, the kit I got had the spacers missing so I called. It was late Friday by thus time but they took care of the issue first thing Monday morning and I got the spacers on Tuesday. Great company.
