Artec Industries is excited to announce our new JL Rear Inner Fenders. These aluminum fenders not only protect your rear wheelwell compartment from dirt and debris but do it in style. Our proprietary process of stamping our logo not only adds an additional element of style not seen in the industry but also increases the rigidity of the whole inner fender.
Features:
- Proprietary A-blade stamping process for increased rigidity and mackdaddy status
- Lightweight 1/16 inch Aluminum construction
- CNC laser cut and CNC bent for precise fit
- Can be used with most other aftermarket fenders
- Compatible with OEM fenders
- Price is per pair - Includes Passenger and Driver side 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 powdercoat 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, powdercoating 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. See instructions for hole locations to determine if modification will be necessary to install with aftermarket fenders.
While aluminum is corrosion resistant, it is recommended to have some type of coating for long term corrosion protection.

I recently ordered a set of control arms from Core 4x4, and the entire experience was absolutely top-notch from start to finish. The ordering process was smooth, the parts arrived quickly, and the control arms themselves are extremely high quality—solid construction, great finish, and clearly built to last.
I also want to give a special shout-out to Korby, the guy I spoke with during the process. His customer service was amazing. He went above and beyond to make sure I got exactly what I needed, answered all my questions, and made the whole experience stress-free. You don’t see service like that very often these days.
If you’re looking for high-quality suspension components backed by truly exceptional customer service, I highly recommend Core 4x4. I’ll definitely be buying from them again.

Core 4x4 excels with precision and service and keeps nothing else higher in mind. Everyone I've met at the company is very honest and down to earth, 10/10 would recommend.

Great long arm kit with everything else I needed as well! They worked with me to ensure that I was getting an upgraded components kit just like I wanted. Fast shipping with some of the best packaging that I have ever seen. Nothing was scratched or missing and this kit is even more impressive than the videos or website can show. Powder coating looks great with no issues.
I would highly recommend CORE 4x4 to anyone looking for a great quality kit.

Great products they sell, got a crawl series long arm kit for my xj and it has held up quite nice, they are beefy, and for what ever reason they fail it has a great warranty with a customer service to match, when someone asks what control arm kit to buy I always recommend core 4x4

In September 2025, we visited CORE 4x4 in Orem, Utah. CORE 4x4 makes control arms and other similar parts that stiffen the suspension of an off-road 4x4 vehicles, so that the off-road vehicles can travel on more rugged terrain. CORE 4x4 used to share this building with another business, and since this other business has moved elsewhere, CORE 4x4 will continue to expand and grow their business. Good for CORE 4x4 to be a growing company and to expand into the vacant part of the building.

Core 4x4 has outstanding products at a fair price and unmatched customer service. When you call Korby, it's like talking with a friend. Very cool and helpul!
I ordered some custom control arms, but from the wrong product line and they were super cool about returning them and upgrading to a better "Crawl" series. Only charged the difference between the two products. They paid all the return shipping and sent the uprgaded arms super quick. It was only a couple days. Awesome!!
I couldn't be happier with the transaction👍🏼
Also, these control arms are stout and take a beating. I run heck out my Jeep in the rocks and desert. No problems whatsoever.
Thanks Core 4x4, ya'll are welcome at my campfire anytime!

I have bought a bunch of sets of arms, track bars and even had custom work done by Core 4x4. Just yesterday, Spence and Cam delivered an awesome cross member they designed and built for me! All of their products have been exceptional! I have personally seen their progression with design changes/updates. They truly take pride in their work and products. Quality control is second to none! They’ve also helped me diagnose issues with different jeeps I’ve had, as well as Dodge/Rams. These guys know their stuff! Really! I trust them whole heartedly and absolutely love their products/quality of work! I’ve referred many people, and will always continue to do so. Keep up the good work Core4x4!

I ordered the jeep xj long arm lift kit. Control arms showed up first they turned out amazing!! Had some issues with the powder coating on the cross member and sent korby and the team at core4x4 an email. They got right on making me another cross member and sending it out. I appreciate all the help they've given me along the way. Very fast response thru emails. Build quality seems to be pretty dang nice!! Can't wait to install it and enjoy it!
