Thanks to Apex Chassis, another heavy duty ball joint upgrade is available to solve your ball joint woes. Apex Chassis has decades of experience in building quality steering components for heavy duty applications. If you have excessive tire wear, cambered tires or the dreaded death wobble, these ball joints can help alleviate those issues. The upper ball joint is a king-pin style and made to rotate on it's axis and go up and down. The lower ball joint is a true ball joint in the sense of a ball stud resting in a socket (think shoulder or hip joint).

Apex has gone through the OE ball joints and found dozens of ways to improve on the ball joints for the Chevy/GMC HD's. From stronger materials to redesigns of grease channels, a fresh new look has been given to these joints to ensure a stronger and more durable part. Apex is so confident in the build of their part that they offer a limited lifetime warranty for them if you ever need it.

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: Makes parts and bearings dimensionally perfect, eliminating any die wear issues.

• 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.
• Polished Ball Studs: Are built like an anti-friction bearing with extremely precise tolerances.
• 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).

• UPPER: 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.
• LOWER: Rugged Metal to Metal Bearing.
  

• 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.
• Compression Boot
  

• Phosphate Finish: Extremely durable. Double coated. Rugged look.

• Grade 8 - Class 10.9 Hardware: Superior tensile strength
• Castle Nut: Industry standard where high vibration loads occur.

• 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.
