Apex Chassis Super HD Upper Ball Joint 94-99 Ram | 80-22 F-250/F-350 4WD

Built for the heaviest-duty Ford and Dodge Ram trucks on the road, the Apex Chassis Super HD Upper Ball Joint delivers unmatched strength, precision, and reliability. Designed for demanding 4WD and work-truck environments, it’s the perfect upgrade for everything from Dodge Ram to classic F-Series rigs to modern Super Duty haulers.

Each joint is constructed around a solid forged SAE 1045 steel housing for maximum structural integrity and a hot-forged SAE 4140 Chromoly ball stud, engineered to handle extreme vertical and torsional loads. Apex’s military-grade acetal bearing provides smooth, consistent movement without metal-on-metal wear—ensuring rock-solid steering feel and long service life under punishing conditions.

Every component is CNC-machined for perfect dimensional accuracy, induction heat-treated for consistent strength, and E-coated for corrosion resistance. The CR rubber internal seal boot keeps contaminants out while resisting damage from ozone, oil, and temperature extremes. With pre-threaded zerk fittings, gull-wing grease grooves, and pre-greased internals, installation and servicing are fast, clean, and worry-free.

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

• 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.
• Internal Seal Boot: The boot is coined onto the ball joint, for superior sealing against contaminants.

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 favorite.
• 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: Multiple Zerk fittings included for each application.
