Whiteline Rear Upper Control Arm – 2008-18 Ford Focus / 2007-2013 Mazda 3 / 2006-2013 C70 / XC70 / C30 / 2006-2011 S40 / V50

Whiteline Rear Upper Control Arm – 2008-2018 Ford Focus / 2007-2013 Mazda 3

Upgrade the Rear Upper Control Arm on Your Focus or Mazda 3
Whiteline’s rear upper control arm for the 2008-2018 Ford Focus and 2007-2013 Mazda 3 is a quality replacement arm built to an improved specification over OEM, with bushing geometry optimized to maintain correct rear wheel camber and toe under cornering and braking loads. These platforms use multi-link or torsion-beam rear arrangements depending on variant — where multi-link is used, the upper arm is a primary geometry component.

DETAILS

• High-quality replacement rear upper control arm
• Improved bushing geometry over OEM specification
• Maintains correct rear wheel camber and toe under load
• Fitment: 2008-2018 Ford Focus and 2007-2013 Mazda 3
• Direct bolt-in replacement

Focus and Mazda 3 Rear Suspension Architecture
Both the Ford Focus and Mazda 3 in these generations use a rear suspension layout where the upper control arm is a significant geometry element on multi-link equipped variants. Worn upper arms or arms with failed bushings allow rear wheel geometry to vary under load — producing the rear instability and inconsistency that develops on high-mileage examples of these popular platforms.

Focus ST Application
The Focus ST (Mk2 and Mk3) is particularly relevant for this upgrade — it’s a performance-oriented variant that’s driven hard and where rear suspension precision matters for consistent handling balance. Quality replacement arms ensure the rear geometry stays correct under performance driving loads.

When to Replace the Arm
Replace when the OEM arm has failed bushings, cracked components, or damage from road hazards. Whiteline’s replacement provides a quality alternative with improved bushing specification that will outlast the OEM unit.
