Apex Chassis KIT211 Extreme Duty Upper And Lower Ball Joint Kit

Replace the old ball joints on your truck with the Apex Chassis KIT211 Extreme Duty Upper And Lower Ball Joint Kit from XDP. The ball studs offered are made from SAE 4140 Hot Forged Chromoly for optimal metallurgy. The induction heat treatment process used provides precise heat treatment to the ball studs at exact depths and locations. Polished ball studs have anti-friction bearings with precise tolerances. Rolled threads are used for added strength by pressing the shape of the threads into the ball stud instead of cutting. Step threads allow for easy hardware movement on installation and superior holding when torqued.

The upper carbon-bearing design is ideal for Jeep and Dodge upper ball joints. The lower military-grade acetal bearing material is specified by the US military for Hummer ball joints due to its stability, anti-friction properties, and durability. CR rubber boots are used to resist deterioration from road-level ozone, oil/gas/engine fluids, and extreme temperatures. The internal seal boot is coined onto the ball joint for superior sealing against contaminants. The upper has a durable e-coat treatment, while the lower has a double-coated phosphate finish for a rugged look. Superior tensile strength is offered by the grade 8-class 10.9 hardware, and the castle nut is an industry-standard for high-vibration loads. The pre-threaded zerk housing feature is a simple but useful addition, and all ball joints are pre-greased with included zerk fittings. The gull-winged grease grooves allow for improved lubrication disbursement, and the lower ball joints have custom features such as a side angle zerk housing with an extended zerk fitting for easier maintenance.
