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

A must for lowered vehicles, Whiteline roll centre correction kit, is designed to correct roll-centre geometry using specially engineered ball-joints. Raising the front roll-centre results in a substantial increase to front roll resistance and a significant reduction in suspension compression on the outside front tyre during cornering. The result is more even weight distribution and improved tyre contact ultimately improving front end grip, cornering speeds and tyre life when driving the vehicle to it?s potential.
