Kryptonite Upper & Lower Ball Joint 99-22 Ford F250/350 99-04 F450/550 | 94-99 Ram 4WD

If your Ford SuperDuty or RAM is showing signs of worn ball joints like abnormal tire wear, steering wander, or vibrations, don’t settle for generic replacement parts. Upgrade to Kryptonite Heavy-Duty Upper & Lower Ball Joints, built to handle the toughest work while providing reliable, long-lasting performance. These ball joints are engineered for heavy-duty trucks and off-road use, with oversize internals and heat-treated 4140 chromoly studs for superior strength and durability.

Each ball joint comes pre-greased with Chevron Ultra EP2 grease and features a durable E-Coat finish to resist corrosion and maintain performance integrity. A serviceable grease port allows for continued maintenance, and the direct-press-in design ensures a proper OEM fit. Note that a break-in period is normal after installation, and you may notice initial stiffness or a simulated memory steer depending on your vehicle setup and driving conditions.
