Rr Sway Bar Bushing Set 21mm

The Energy Suspension Rear Sway Bar Bushing Set 21mm is a high-performance polyurethane suspension component engineered to replace worn factory rubber bushings on 2003–2009 Nissan Z models. This pair of Hyper-Flex bushings significantly improves chassis responsiveness by reducing bushing deflection during cornering, body roll, and acceleration—key performance gains for both street driving and track use.

Engineered from premium polyurethane material in black, these 21mm rear sway bar bushings deliver superior durability compared to original rubber components that degrade over time from heat, UV exposure, and constant flexing. The Hyper-Flex compound maintains consistent stiffness across temperature ranges, translating to more predictable suspension geometry and reduced wheel hop during aggressive cornering. Installation requires basic hand tools and fits directly into factory mounting locations without modification.

This bushing set addresses a critical weak point in aging Z33 and Z34 chassis where original rubber bushings harden and crack, allowing excessive sway bar movement and blurring steering feedback. Upgrading to polyurethane bushings is a foundational suspension mod for drivers seeking sharper handling without the cost of a complete sway bar replacement. The 21mm diameter matches factory specifications for rear applications on these models, ensuring proper fitment and suspension geometry alignment.

Energy Suspension is recognized for polyurethane suspension components that balance performance with durability, making this rear sway bar bushing set a trusted choice for Z platform enthusiasts upgrading handling characteristics without modifying other suspension elements.
