The Special Sauce:
- HOUSING
- SAE 1045 Solid Steel Forged Housing:This is unequivocally the best carbon alloy steel for this application.
- Knurled Housings:The preferred design for aftermarket installations.
- CNC Machined Housing:Make our parts and bearings dimensionally perfect, eliminating any die wear issues.
- BALL STUDS
- SAE 4140 hot forged Chromoly Ball Studs: for strongest possible metallurgy.
- Plunger Design Stud:Unique to Jeep and Dodge, allows up and down movement with no side-to-side movement.
- Induction Heat Treated Ball Studs:provides a very precise heat treatment to the exact depth and location we want it.
- Rolled Threads: are made by pressing the shape of the threads into the ball stud instead of cutting. This strengthens the threads instead of weakening them and allows for easy movement of hardware. This ain't no Ikea furniture!
- Step Threads :allows for very easy movement of hardware on install and superior holding when torqued (installer choice).
- BEARING DESIGN
- Carbon Bearing Design:Used mainly in Jeep and Dodge upper ball joints is the solver of all things wobbly. Like all of our product.
- BOOTS
- CR Rubber Boots:The most durable material for undercar applications.
- Pancake Boot
- HARDWARE
- Grade 8 - Class 10.9 Hardware:Superior tensile strength.
- Castle Nut:Industry standard where high vibration loads occur.
- LUBRICATION
- Pre-threaded Zerk Housing:If you have ever installed a MOOG ball joint without a pre-threaded zerk fitting you will understand what a simple but great feature this is. Another installer fav.
- Greaseable:Because it should be.
- Pre-Greased:Just in case you forget, we have you covered.
- Gull Winged Grease Grooves:Allows for improved lubrication disbursement.
- Zerk Fittings:Included for every application.

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.

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

Korby was extremely helpful in helping me find the right part for my truck. He was kind, knowledgeable, and patient while I asked a million questions. He also went out of his way to find the right shipping option for me since it’s tricky where I live. I’m looking forward to getting the parts so I can fix my truck and go adventuring again soon!

The whole process was quick and painless. The products are top tier and when I reached out them for package update info, Korby Linscomb was very responsive, and got me the answers I needed the same day. Even when I emailed back to some additional info, he sent what I was looking for that same day. I love core 4x4 and will be giving them my business from now on.
