  • Induction-hardened studs: hardened to maximize strength, resist breakage and improve fatigue life.
  • Pre-installed dust boot seal: provides a barrier against wear-causing contaminants.
  • Added corrosion protection: specially-engineered coatings applied to metal surfaces to inhibit deterioration from rain, snow, salt and road grime.
  • Premium bushings: pre-installed with optimized stiffness to inhibit noise for a comfortable ride.

Precision tolerances are designed for easy installation and steering alignment. If a worn control arm or ball joint on your Audi or Porsche is the cause of clunking, wander or uneven tire wear, this assembly replaces it. Have a wheel alignment performed after installation.
