Apex Chassis KIT111K Extreme Duty Upper & Lower Knurled Ball Joint Kit

The Apex Chassis KIT111K Extreme Duty Upper & Lower Knurled Ball Joint Kit will replace the worn-out ball joints in your RAM 2500/3500 4WD. Knurled units are recommended for trucks where the factory ball joints have been replaced or high mileage applications.

Ball Joint Housing

SAE 1045 Solid Steel is unequivocally the best carbon alloy steel for forged housings that utilize the knurled design for aftermarket installations. Apex Chassis uses CNC Machined housing to make parts and bearings dimensionally perfect, eliminating any die wear problems.

Ball Studs

For the strongest possible metallurgy, these ball joints use SAE 4140 Hot Forged Chromoly Ball Studs. Induction Heat-Treated Ball Studs deliver extremely precise heat treatment to the precise depth and location Apex wants it. Polished Ball Studs are manufactured with extremely precise tolerances and Built like an anti-friction bearing. The threads are made by pressing the shape of the threads into the ball stud instead of cutting, thereby strengthening them and allowing for easy movement of hardware. These step threads offer superior holding when torqued down and allow for very easy movement of hardware upon installation.

Bearing Design

Using the same bearing material spec'd by the US military for Hummer ball joints, these ball joints come with military-grade Acetal bearing. This dimensionally stable material doesn't expand or contract with hot or cold temperatures and does not absorb water or oil. The surface of this material can be polished as smooth as steel, offers anti-friction properties, can take an absolute pounding, and doesn't wear out under load like metal on metal.

Boots & Hardware

CR Rubber Boots are some of the most durable materials for the underside of automotive applications. This material is resistant to deterioration from road-level ozone, oil, fuel, engine fluids, and extreme hot or cold weather. The upper ball joints use a pancake boot while an internal seal boot is coined onto the lower ball joint for exceptional sealing against contaminants. Superior tensile strength is offered by the Grade 8 - Class 10.9 Hardware and the castle nut is an industry standard where high vibration loads happen.

Lubrication

If you have ever installed a ball joint without a pre-threaded Zerk fitting, you know what an outstanding feature this is. These pre-greased ball joints feature gull-winged grease grooves that allow for better lubrication disbursement around the ball stud.
