Product Details

This Whiteline Rear Upper Inner Control Arm Bushing Kit fits the 2004-2013 Mazda 3 i, S (BK/BL). Application note: Suits cast arm. On-car adjustable allows +/-1.0 degrees Camber. The kit contains 2 shell bushings and 2 tubes. Position: rear. Whiteline part number: KCA394.

Camber is the sideways lean of the wheel when viewed from the front. An offset control arm bushing places the pivot slightly off-center, which shifts the wheel's camber by a small, fixed amount without replacing the arm. On a lowered car that is often enough to bring the tires back toward an even footprint.

Whiteline rates the install as moderate and lists about 2 hours. An alignment is required after installation. Other Whiteline parts we list for the Mazda 3: Adjustable Rear Sway Bar Link, Adjustable Rear Upper Control Arm Set, and Adjustable Front Sway Bar Link.

Features

  • Install guide: Step-by-step installation instructions come with it.
  • Material: Polyurethane construction.
  • Finish: A powder coated finish resists corrosion and wear.
  • Bushing compound: The bushing material stands up to oil, grease, ozone, and weather.
  • Grease: Moly grease is supplied to prolong the life of the parts.
  • Bonded design: A bonded design adds strength for high load applications.
