Product Details
These Whiteline Rear Upper Control Arms fit the 2007-2013 Mazda 3 Mazdaspeed Base. The listing names the Mazdaspeed Base trim. Position: rear. The kit contains 1 arm. Part number WA402. Whiteline's note for this fit: Left hand or Right side only. Complete arm fitted with bushings.
The rear upper control arm helps decide how the top of the rear wheel leans, which makes it a main control for rear camber. A fixed factory arm offers little room to change that angle. This adjustable set gives the alignment shop a way to set rear camber to the target, which supports even tire wear and consistent grip.
Expect an easy job of about 2 hours. An alignment is required after installation. Working on the same car? We also list Adjustable Rear Sway Bar Link, Adjustable Front Sway Bar Link, and Front and Rear Sway Bar Kit for the Mazda 3.
Features
- Self-lubricating: Internal grease reservoirs keep the bushing lubricated as it works.
- Grease: Molybdenum disulfide grease comes with it for a longer service life.
- Finish: An E-coat finish protects the metal from corrosion.
- Bushing compound: Oil, grease, ozone, and weather do not break down the synthetic elastomer used in the bushings.
- Easy to fit: Designed so the install needs no specialized skills or tools.
- Corrosion protection: Plated finish keeps rust off the hardware.
