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.

I purchased a upper and lower set of control arms from core 4x4 they came early then expected and seem to be very nice quality I ran into a complication installing them and emailed them my question I was expecting to get the response maybe the next day because it was after hours I got a response in about a few minutes which allowed me to finish the project that day I super appreciate that, the products are good strong lifetime warranty and their customer service is top notch

Installed rear and upper control arms and track bar on my 3rd Gen 4RUNNER to align rear axle and restore factory wheel base after 3.5" lift. Car drives better than New! Improved handling cornering and overall driving. Very solid and high quality made product. Support is outstanding. Shipping extremely fast.
Thank you so much. I wish you will have something new for my car.

The customer service is first class. I had an issue with a track bar I installed on my F350. I don’t have any other Core 4x4 parts yet, but with the way I was treated, I know their parts are well done, because they went above and beyond to make sure I was made whole. They wouldn’t be in business if they had to take care of a lot of people like they took care of me. Will definitely be back when it’s time to build the Jeep!
