Teraflex HD ball joints are the ultimate deal when it comes to maintaining your vehicle's alignment and preventing failure. Replace your tired ball joints with a fresh set of the revolutionary Teraflex Dana ball joints for efficient handling of the increased load caused by oversized tires and offset wheels.

The upper ball joint features hard sintered metal bearings to handle the rotational load without failure.The lower ball joints have a threaded top cap giving a precise preload tolerance, precise steering and prolonged joint life. The lower ball stud has a unique flush needle zerk that is offset for u-joint clearance and easy grease servicing without axle shaft removal, even with the larger RCV shafts. The lower ball joint also features a hard alloy special plate made from high carbon tool steel for maximum wear resistance as the lower joint must bear the vehicle's weight. A CR Black Neoprene boot is fitted into position with a spring and steel ring. Both ball joints have a grease zerks passage that allows regular maintenance without affecting the ball joint load surface.

Each of the ball joints is constructed from 4140 chrome moly steel with magnesium phosphate anti-corrosion coating for high hardenability and increased resistance to wear and abrasion. The 4140 chrome moly steel significantly increases overall ball joint strength and durability. The ball joint set also features a 1045 carbon steel housing and a factory style serrated flange nut and grease fitting.

The Teraflex HD ball joints are perfect for use in Dana 30 or Dana 44 Jeep Wranglers. The ball joints with knurls offer the extra grip needed for ball joints with a loose fit in the inner knuckle due to repeated ball joint replacement that may have enlarged or wore the mounting location.
