Yukon Gear & Axle Heavy Duty Upper & Lower Ball Joint Kit

2002–2018 Dodge Ram 1500, 2500, 3500 with AAM 9.25in Front Differential

YSPBJ-004HDK2

Overview:

The Yukon Gear & Axle Heavy Duty Upper & Lower Ball Joint Kit is engineered to replace and upgrade the original equipment (OE) ball joints on Dodge and Ram trucks equipped with the AAM 9.25-inch front differential. Designed for durability and long-lasting performance, this kit is ideal for truck owners seeking to eliminate common suspension issues such as premature wear and the dreaded death wobble. Whether you drive a Ram 1500, 2500, or 3500 from model years 2002 through 2018, this kit offers a precision-built solution that enhances front suspension reliability and smoothness.

Built to withstand the rigors of daily driving, towing, and off-road use, Yukon’s heavy-duty ball joints provide superior strength and protection compared to factory units. This kit replaces both upper and lower ball joints on both sides of the front suspension, restoring proper steering geometry and improving vehicle handling.

Key Features:

Yukon’s ball joint kit incorporates advanced materials and design improvements to deliver exceptional durability and performance:

• CNC-machined housing forged from SAE 1045 carbon alloy steel for enhanced strength and longevity
• Hot-forged, induction heat-treated 4140 chromoly ball studs for unmatched toughness and wear resistance
• Upper ball joint features a carbon steel bearing superior to OE designs for smoother operation
• Lower ball joint uses military-grade acetal bearings, providing excellent anti-friction properties and dimensional stability
• Two-stage sealing system with a synthetic Neoprene/CR outer boot and an internal seal/pancake boot to protect against dirt, oil, gas, and extreme temperatures
• Extrusion rolled threads on hardware for significantly stronger fastening compared to cut-thread construction
• Greaseable, pre-threaded zerk fittings for easy maintenance and lubrication
• Includes Grade 8 hardware, castle nuts, c-clips, cotter pins, and all necessary small parts for a complete installation
• Lifetime warranty against manufacturing defects

Construction & Design:

Every component in this Yukon ball joint kit is crafted with precision and high-quality materials to ensure maximum durability and performance. The housings are CNC-machined from forged SAE 1045 carbon alloy steel, providing a robust foundation that resists deformation and wear under heavy loads. The ball studs are manufactured from 4140 chromoly steel, which undergoes hot forging and induction heat treatment to achieve superior hardness and toughness.

The upper joint’s carbon steel bearing offers a smoother, longer-lasting interface than standard OE units, while the lower joint’s military-grade acetal bearing delivers exceptional anti-friction performance and dimensional stability, reducing wear and extending service life. The dual-boot sealing system combines a synthetic Neoprene/CR outer boot with an internal seal to effectively block contaminants such as road grime, oil, and engine fluids, even in extreme temperature conditions.

Installation & Fitment:

This heavy-duty ball joint kit is designed as a direct replacement for the upper and lower front ball joints on Dodge Ram trucks equipped with the AAM 9.25-inch front differential. It fits a wide range of models, including Ram 1500 (2003–2010), Ram 2500 and 3500 (2003–2018), covering trims such as Laramie, SLT, Sport, SRT-10, ST, SXT, TRX, TRX4, Power Wagon, Big Horn, Longhorn, Lone Star, Outdoorsman, and Tradesman.

Installation requires standard suspension tools and mechanical knowledge. The kit includes all necessary hardware, such as Grade 8 bolts, castle nuts, c-clips, cotter pins, and grease fittings, ensuring a hassle-free replacement process. Note that a 300- to 500-mile break-in period may be required during which some memory steer could be experienced as the joints settle.

What's Included:

• 2 Upper heavy-duty ball joints
• 2 Lower heavy-duty ball joints
• Grade 8 hardware
• Castle nuts
• C-clips
• Cotter pins
• Pre-threaded greaseable zerk fittings
• Installation instructions
