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 Rear - Outer Bushing Kit to Suit Mazda MX-5 ND

Description

Benefit Note: Eliminate unwanted compliance and unlock the full potential of your ND Miata rear suspension with this Rear Knuckle Bushing Kit. The factory rubber-injected bushings with metal sleeves offer a comfortable ride for the street—but at the cost of performance. Under aggressive driving, these OEM bushings deflect and bind, introducing instability and alignment changes through corners that limit grip and driver confidence. Our kit replaces the soft factory components with Whiteline's synthetic elastomer bushings. This upgrade removes the "mushy" feel from the rear end, eliminates artificial spring rates, and ensures maximum grip and consistent handling at the limit.
