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.

Have full upper/lower CA set on both front and rear axles on a 96 ZJ. These are the rubber bushing sets not joint sets. I have beat the hell out it in the Nevada desert for 2 years and has been great. I don’t go fast but I do articulate suspension a lot. Super solid and haven’t any issues. Just inspected the entire set recently due to some banging under it. Turns out the banging is lower rear shock bushings. Inspected each CA along the way nothing. Aside from dirt and obviously winter roads and what not still in excellent condition, bushings are solid like the day they were installed. I’ll add that I’m about tapped on a short arm at 4.25(less with settle) so the front CA’s get beat on just from that, still they’re like new. Paint is great condition, this set is red. I would definitely buy again. Another plus for me, Utah isn’t local necessarily, but it’s nice to support businesses closer to me.

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.

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.
