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.

I have recently come to know Core 4x4 when I purchased a Jeep XJ and was looking for a place that had dedicated XJ suspension and components. Here is what makes them different than most other shops. All of their components are top shelf quality and they back it up if you break any of it. I was able to see their shop when I picked up an order locally and was impressed with their attention to detail and how they assemble and powder coat each part. I had an issue with a shackle and needed the threaded shaft to be shorter. I called in and talked to Kaden and he told me to come by and they would shorten it for me. When I got there, Kaden and Spencer (the owner) met me and talked about options and proceeded to make the right adjustments to fit my XJ. Told me if anything changes in the future and I need additional length, they would take care of me. So what really sets them apart from others is their Customer Service. Try calling in to any other Jeep suspension or part shop and see how they treat you. Been there - done that.
Will continue to do business with Core and their team. Getting that kind of service for just a shackle has me thinking I may need to replace my JT components with Core's. Thanks Guys for being helpful good humans!

Purchased a set of Trailing arms for my Ram 1500, quality is first class. I bought the ones with the Jonny Joints for more articulation and it appears from the construction I should get a lifetime of use, Zerk fittings are an added plus. Would defiantly recommend, and the the service team answered all of my questions.

I have a 2016 RAM 1500 Crew Cab and I replaced the rear upper and lower control arms also the pan hard track bar and also the sway bar and links for the rear with all I had the articulating bushings. The vehicle now has no body role. They are absolutely incredible if you get the control arms you gotta get the CORE 4 x 4sway bar end links don’t don’t try and be cheap and get Moog or something else you got to get articulating bushings get the core 4 x 4 ones they are the best. My truck drives now through the canyons like a BMW. I have Fox high-performance shocks on there as well with all the CORE 4 x 4 suspension parts and they are amazing. Well worth the money I would highly recommend anybody thinking about CORE 4 x 4 go with CORE 4X4 and if you can go with their articulating bushings, they’re unbelievable drives better now than my Escalades. Well planted no body role and smooth on the Highway unbelievable the difference they all made!!
THANKS AGAIN CORE 4x4!!!!

I want to share a truly positive experience.
I ordered a car kit consisting of two packages, but unfortunately one was lost during shipping with UPS. The situation could have become complicated... but it didn't.
The company manager was extremely helpful and professional: he personally followed up on the situation and did everything he could to resolve the issue, even sending me the package again without hesitation.
It's rare to find such attentive and reliable customer service these days.
My sincere congratulations on your professionalism and commitment: that makes all the difference.
