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 the strongest possible metallurgy.
  • Induction Heat Treated Ball Studs: Provides a very precise heat treatment to the exact depth and location we want it.
  • UPPER: Plunger Design Stud:Unique to Jeep and allows up and down movement with no side-to-side movement.
  • LOWER: Polished Ball Studs: Built like an anti-friction bearing with extremely precise tolerances.
  • Rolled Threads: 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

  • UPPER: Carbon Bearing Design: Used mainly in Jeep and Dodge upper ball joints is the solver of all things wobbly. Like all our products.
  • LOWER: Military Grade Acetal Bearing: The same bearing material spec'd by the US military for Hummer ball joints. This material is: dimensionally stable (doesn't expand or contract with hot or cold, water or oil absorption), it can be polished smooth as steel, is anti-friction, Doesn't wear itself out under load like metal on metal, and can take an absolute pounding.

BOOTS

  • CR Rubber Boots: The most durable material for undercar applications. Resistant to deterioration from road level ozone, oil/gas/engine fluids and extreme heat or cold.
  • Pancake Boot

FINISH

  • E-Coating: Extremely durable electrochemical finishing process

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 around the ball stud.
  • Zerk Fittings: Included for every application.

SPECIAL FEATURES

  • Custom Features: UPPER: Custom Bearing design to eliminate Death Wobble.
  • Custom Features: LOWER: Angled Zerk housing for easier servicing.

Where It Fits:

Vehicle Position: Front Upper, Front Lower

Quantity per Vehicle: 1

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 nothing but great things to say about this company and their customer service. If you like American made products backed by warranty and amazing customer support, this is the company for you. I have a Lexus GX470 and love their rear control arms.

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.

Core 4x4 has outstanding products at a fair price and unmatched customer service. When you call Korby, it's like talking with a friend. Very cool and helpul! I ordered some custom control arms, but from the wrong product line and they were super cool about returning them and upgrading to a better "Crawl" series. Only charged the difference between the two products. They paid all the return shipping and sent the uprgaded arms super quick. It was only a couple days. Awesome!! I couldn't be happier with the transaction👍🏼 Also, these control arms are stout and take a beating. I run heck out my Jeep in the rocks and desert. No problems whatsoever. Thanks Core 4x4, ya'll are welcome at my campfire anytime! Jake T. Pleasant Hill, Or.

To start off if you're looking to upgrade your control arms definitely hit this company up. Great product, easy install of the product, with three different tiers everything is priced pretty good, I'm a sticker guy and they sent a sticker for each arm each track bar and also three extra ones so the extra are on the Jeep the advertise them for sure. If you're reading this review I highly recommend you to check their website out.

First of I just want to say Great customer service korby Has helped me from the start and has not let me down! Reached out to him again today and he was able to warranty some parts out for me. As far as the quality of the parts.. excellent! The build quality is great. I can definitely tell a Difference from the cheap oem rear control arms to these and the pan hard bar. Color, From what I can tell it’s super durable been through a few mud holes on top of the daily road grime and after a quick wipe they still pop! Overall I recommend. Customer service is everything for me and it’s definitely there at Core 4x4.

Great Experience. I wanted to make changes to my order and Korby was more than willing to work with me to get everything corrected. Hope to deal with these guys again in the future.

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.
