Rear Height Adjuster - ZN-01-ZN-02-ZN-03-HLK
SKU: ZN-01-ZN-02-ZN-03-HLK
Description
Rear height adjusters are designed for suspension setups that use a separate spring and shock configuration, where the spring sits in a control arm spring bucket rather than being mounted on the damper.
Unlike a true coilover system—where ride height is adjusted directly through the damper—separate spring and shock setups rely on the spring assembly to determine vehicle ride height, while the shock absorber primarily manages damping and spring preload.
Rear ride height on these applications is adjusted using the rear height adjuster, which allows for precise height changes at the spring location.
Over time, suspension components can become lost, damaged, or worn due to exposure to weather and road conditions. These rear height adjusters are available individually per side as replacement components and include the necessary lock rings for proper adjustment and secure installation.
