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.
  • 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
  • Phosphate Finish: Extremely durable. Double coated. UPPER: Threads coated as well. Rugged look.
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.

Very Stout!

Still in the process of installing, have one side done but work gives me little time. These joints are very stout, the little bit of play I was getting concerned about will surely be gone when I complete the job. Can't wait to drive it!!

I have not had time to install them yet. They arrived in good condition and appear to construct from very durable materials.

01 Jeep Cherokee XJ

Bought these for my XJ and they are awesome! Install was super easy! It tightened up my suspension and steering. Would definitely recommend! It does come with snap rings but for the xj they are not needed, it may look like the bottom ball joint does not sit all the way up top but confirmed with Apex that is the way they go it allows clerance for the zerk fitting. Apex definitely makes quality products and you can’t beat the lifetime guarantee!
