Yukon Ball Joint Kit for Jeep Wrangler JL & Gladiator JT, Both Sides_x000D_
_x000D_
Superior materials lead to superior performance. When you replace and upgrade your failing OE ball joints with a heavy-duty Yukon unit you get a ball joint built to the highest standards of quality and durability. Its housing is CNC-machined from forged SAE 1045 carbon alloy steel and the ball stud is made from induction heat-treated, hot-forged 4140 chromoly. These ball joints feature an improved bronze bearing that is highly durable, low-friction design. Ball joints are only as durable as the protection provided by their rubber boots. These Yukon ball joints feature a two-staged approach with a synthetic Neoprene/CR outer boot and an inner seal/pancake boot that safeguard the spherical joint and bucket against gritty road grime, oil, gas, and engine fluids, and extreme temperatures. This kit replaces the upper and lower front ball joints on both sides and includes Grade 8 hardware, castle nuts, c-clips, cotter pins, and zerk fittings._x000D_
