Built to outperform and outlast in the most demanding work-truck and off-road environments, the Apex Chassis Super HD Lower Ball Joint is engineered for the toughest Ford Super Duty and Dodge Ram platforms. Whether you’re towing, plowing, or tackling rugged terrain, this joint delivers unmatched strength, stability, and precision steering control.

Each joint features a forged SAE 1045 solid steel housing for maximum durability and a hot-forged SAE 4140 Chromoly ball stud—heat-treated and polished to exact tolerances for superior strength under load. Apex’s military-grade acetal bearing eliminates metal-on-metal wear, providing ultra-smooth articulation and long-term reliability even under extreme stress.

Precision CNC machining, induction heat treatment, and E-coating ensure consistent performance and corrosion resistance, while the integral pancake-style CR rubber boot seals out contaminants and withstands harsh environmental abuse. With pre-threaded zerk fittings, gull-wing grease grooves, and pre-greased internals, installation and maintenance are clean, easy, and professional-grade.

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.
• Integral Pancake Boot

HARDWARE

• Grade 8 - Class 10.9 Hardware: Superior tensile strength.
• Tension Nut: Very strong hold in most applications.

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.
