Built to handle the massive torque and front-end weight of GM’s trucks, the Apex Chassis Super HD Upper Ball Joint is purpose-built for strength, precision, and longevity. Whether your Silverado or Sierra HD is towing heavy, hauling equipment, or working hard on- or off-road, this joint keeps your diesel’s steering geometry precise, suspension stable, and articulation smooth under the toughest conditions.
Each joint is crafted from forged SAE 1045 solid steel for maximum structural integrity and features a hot-forged SAE 4140 Chromoly ball stud, polished and heat-treated to deliver unmatched strength and wear resistance. The rugged metal-to-metal bearing design ensures superior load handling and steering accuracy, ideal for high-torque diesel applications where failure is not an option.
Precision CNC machining, induction heat treatment, and an E-coated finish guarantee durability and corrosion resistance in any environment. A compression-style CR rubber boot seals out contaminants and holds in grease, while the pre-threaded zerk housing makes service fast and simple. With gull-wing grease grooves, pre-greased internals, and Grade 8 hardware, this Apex Super HD Upper Ball Joint delivers the professional-grade performance and reliability that GM diesel trucks demand.
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.
• 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).
BEARING DESIGN
• Rugged Metal to Metal Bearing
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.
• Compression 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.
