Engineered for ultimate strength and longevity, the Apex Chassis Super HD Upper Ball Joint is purpose-built for the toughest Ram 2500 and 3500 trucks. Featuring a forged SAE 1045 steel housing and a hot-forged 4140 Chromoly ball stud, this joint is designed to handle extreme load, vibration, and articulation without compromise.

The unique plunger-style stud design—specific to Dodge and Jeep—allows smooth vertical motion with zero lateral play, eliminating the looseness common in factory joints. Apex’s dual carbon bearing system ensures rock-solid stability and extended service life.

Each joint is CNC-machined for precision, induction heat-treated for consistent strength, and E-coated for corrosion resistance. High-grade CR rubber boots protect against ozone, oil, and road contaminants, while the pre-threaded zerk housing, grease fitting, and pre-greased internals make service simple and installer-friendly.

Choose the knurled version for aftermarket or previously serviced knuckles, or the non-knurled version for factory-tight fits. Either way, you’re getting the strongest, most precisely engineered upper ball joint available for heavy-duty Ram trucks.

HOUSING

• Knurled version is ideal for aftermarket knuckle installations or when the bore has become slightly loose from prior replacements.
• Non-knurled version is ideal for OEM knuckles with a tight, original-fit bore.
• SAE 1045 Solid Steel Forged Housing: This is unequivocally the best carbon alloy steel for this application.
• 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.
• Plunger Design Stud: Unique to Jeep and Dodge, allows up and down movement with no side-to-side movement.
• Induction Heat Treated Ball Studs: Provides a very precise heat treatment to the exact depth and location we want it.
• 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

• Dual Carbon Bearing Design: Used mainly in Jeep and Dodge upper ball joints, the solver of all things wobbly. Like all of our product.

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.

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 favorite.
• Greaseable: Because it should be.
• Pre-Greased: Just in case you forget, we have you covered.
• Zerk Fittings: Included for every application.
