All this at a phenomenal price and manufactured in-house which means its Made In The USA!

- Can be used with Artec Nighthawk Fenders and most any other aftermarket fenders-compatible with OEM fenders
- Price is per pair - Includes passenger and drivers ide inner-fenders
- Allows use of larger tires
- Four piece construction per side for lower cost of shipping
- Pressed PEM nuts on seam between pieces for easy installation
- Shipped bare unfinished aluminum for decreased cost and ability for you to paint or powder coat to fit your style
Note:
- While all precautions are made to ensure the aluminum surface is protected, small scratches from either the raw material from the factory, the manufacturing process, or the shipping process may be present in this unfinished product. We recommend you finish this product with either painting, powder coat or another similar process and prepare the surface prior to finishing as you would normally to remove any minor blemishes.
- Mounts to OEM holes on sub-frame plus additional holes to be drilled.
- While aluminum is corrosion resistant, it is recommended to have some type of coating for long term corrosion protection.

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.

Outstanding experience! I asked Core to build me a set of custom control arms that were larger/heavier than they normally build. They gladly accepted the challenge and turned out an expertly crafted and super strong product ahead of schedule. Fit and finish are excellent. Spence and Cameron were a pleasure to work with every step of the way. And all of this for a very reasonable price. I highly recommend these guys!

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!

Absolutely incredible family owned business. I asked to pick up my order since I’m local and they came in on a weekend to accommodate. Had to make some adjustments to parts and took the time to make sure it was perfect. Parts are incredible quality. If you have a Jeep, do not hesitate to support this local business.

Ran into an issue with a part that I ordered. Got ahold of them explained to them the issue I was having and they jumped in and got the issue fixed. Hands down the best customer service I have ever dealt with. The parts are hands down amazing. Highly recommend.

Great company. Highly satisfied with Core 4x4 customer service. Had some bushings fall apart around 600 miles from home. Called and spoke with Korby Linscomb on Thursday, late in the afternoon. He was able to get my bushings sent across country overnight at a very reasonable rate. Had me up and running by Friday evening with enough time to enjoy the Great Smoky Mountain Jeep Invasion. Thanks Guys!
