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.

Rear Control Arm Upper and Lower Front - Outer Bearing kit to Suit Mazda MX-5 ND

Description

Benefit Note: Upgrade your ND Miata’s rear suspension with this Rear Knuckle Bearing Kit, engineered to replace the factory spherical bearings with a higher-precision, zero-play solution. While the OEM bearings offer smooth articulation, they can still develop play, wear under repeated high-load use, and allow small but critical alignment changes during cornering. This Whiteline kit utilizes premium motorsport-grade spherical assemblies designed for maximum durability, minimal friction, and absolute consistency at the limit. By eliminating bearing slop and unwanted compliance, this upgrade ensures precise suspension geometry, sharper feedback, and the confidence to drive your tires to their full potential grip—lap after lap.
