Product Details
Whiteline Rear Lower Trailing Arm Bushing is made for the 2015-2021 Subaru WRX STI Base, Limited. You receive 4 bushings, 2 tubes, an install guide, and grease. Whiteline part number: W63582. It is listed for the VA chassis. The listing names the Base and Limited trims. This part is for the rear of the vehicle.
Bushings work out of sight, but they decide how well a suspension holds its geometry. A soft or tired trailing arm bushing allows play that shows up as vague steering, a wandering feel under braking, or a clunk over bumps. Fitting a firmer one takes that slack out. The polyurethane used here deflects much less than the original rubber under the same load.
Whiteline rates the install as difficult and lists about 2 hours. Get the car aligned once it is back on the ground. To go with it on the WRX STI, see 14mm Adjustable Front Camber Bolts, Adjustable Front Sway Bar Link, and Rear Subframe Mount Bushing.
Features
- Grease: Supplied with molybdenum disulfide grease for extended service life.
- Self-lubricating: The bushing carries its own grease supply in internal reservoirs, so it keeps moving freely.
- Bushing material: Made of polyurethane, which resists deflection better than soft rubber.
- Compliance voids: Molded voids give the bushing room to flex where it needs to.
- Bushing compound: The bushing material stands up to oil, grease, ozone, and weather.
- Easy to fit: Installation does not call for special skills or tools.
