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 short fall of the modern day IFS 4wd is the adjustment range provided for successful wheel alignments, this becomes even more of an issue when the vehicle is lifted by more than 1 inch. Not only does the vehicle run into camber and caster issues, but ball joint articulation and clearance issues to the coil over strut at ride and droop height. The new Whiteline offset UCA (Upper Control Arm) is an all-in-one solution for any vehicle that has been lifted between 30mm and 70mm. Providing an increase between +2.5 and +3.5 degrees of caster and up to 1.5 degrees of negative camber increase (figures quoted are based off an approximate 50mm/ 2 inch) along with greater clearance to the coil over strut and more articulation of the arm by virtue of new maintenance free GIIRO bushing technology.
