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.

Installed the full kit on my XJ. Ride quality is night and day better than what I had before. The articulation on the trail is insane. These guys know what they are doing. Already recommended Core 4x4 to everyone in my club.

Customer service is top notch. They answered all of my questions and got me my tracking number for my packages. I just received both of them and the quality is next level. You guys are truly awesome.

The parts are a massive improvement over factory. I accidentally ordered the wrong endlinks and they helped me figure out the correct size and sent me new ones.
Definitely an awesome store

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.

upper control arms look great and went on easy.. only reason I gave 4 stars and not 5 is because of a shipping issue which put my build a week behind. The issue was resolved quickly and painlessly, great customer service. Only time will tell how control arms perform but they look great and like they will go above and beyond control arm demand.

Exceptional customer service. All my questions were asked in a timely manner and parts were replaced when an error occured. I encourage people to make purchases due to their exceptional quality products, but also because of their customer service. Will make additional purchases in the future.
