What makes Whiteline different from OEM suspension components?

Whiteline suspension products are engineered for performance and durability well beyond OEM standards. While factory (OEM) components often use soft rubber bushings that degrade over time and under load, Whiteline uses advanced polyurethane and bushing technology that resists oil, heat, abrasion, and weathering. This results in sharper handling, more responsive steering, better load control, and significantly improved lifespan — without the harshness of traditional solid bushings.

Do I need a wheel alignment after installing Whiteline components?

It’s recommended to perform a wheel alignment after installation to ensure optimal performance and tire wear.

Are Whiteline Fixed Offset Upper Control Arms (UCAs) necessary for lifted vehicles?

They help maintain correct alignment and steering geometry after a vehicle is lifted.

Can I install Whiteline products myself?

Some products are DIY-friendly, but professional installation is recommended for suspension components.

Do Whiteline products come with a warranty?

Yes. Please refer to our warranty policy for details.

Description

Benefit Note: Upgrade your VA Subaru WRX with Whiteline Alloy Front Lower Control Arms for sharper handling, improved steering response, and enhanced front-end grip. Lightweight alloy construction reduces unsprung weight, while high-performance bushings minimize deflection to maintain precise suspension geometry under load. Engineered with an additional 0.5° of positive caster for improved stability and cornering performance, the kit also includes adjustable spacers that allow anti-lift and anti-dive geometry tuning to suit your driving style. Delivering greater front-end confidence on both street and track, these control arms are the ultimate suspension upgrade for performance-focused WRX owners.
