Product Details
This Whiteline Rear Upper Outer Control Arm Bushing Kit fits the 2000-2004 Subaru Legacy GT, L (BE/BH/BL/BP). Order it as part number KCA399. Application note: On-Car Adjustable Allows +/- 1.25 degrees. Placement: rear. In the box: 4 bushings and 2 tubes.
A control arm bushing is the pivot where the arm joins the chassis or the wheel carrier. Factory rubber is chosen for quiet and comfort, so it squashes under braking, acceleration, and cornering and lets the arm move more than it should. A firmer replacement keeps the arm where it belongs, which steadies the alignment and gives the car a more consistent feel. Polyurethane resists deflection far better than the soft rubber it replaces.
Whiteline rates the install as moderate and lists about 3 hours. An alignment is required after installation. To go with it on the Legacy, see Adjustable Rear Sway Bar Link, 14mm Adjustable Front Camber Bolts, and Front and Rear Sway Bar Kit.
Features
- Grease: Molybdenum disulfide grease is included to help the parts last.
- Bushing compound: A synthetic elastomer compound resists oil, grease, ozone, and weathering.
- Camber adjustment: Helps hold the tire flatter on the road by correcting camber changes through roll.
- Material: The part is made of polyurethane.
- Self-lubricating: The bushing carries its own grease supply in internal reservoirs, so it keeps moving freely.
- Corrosion protection: Metal parts are plated to resist rust over the long term.
