The Buddy Club P1 Racing Extended Ball Joint is manufactured with superb quality and craftsmanship. The ball joint dust boots are sturdy and snug and will withstand heat and the rigors of racing much better than your factory dust boots. The included castle nuts are strong and will not strip. The Buddy Club P1 Racing extended ball joints help return the suspension geometry to its ideal position while still allowing you to lower your cars center of gravity. Furthermore, they maximize vehicle tire grip by allowing increased front camber adjustability.
