🧾 Overview
This premium front coilover shock with a remote reservoir is engineered to enhance suspension performance on light trucks and SUVs by improving damping control, ride comfort, and wheel travel over stock suspension. The advanced ZoneControl CR design uses a multi-piston system to deliver position-sensitive damping, providing smooth everyday driving combined with strong control when encountering rough terrain. Built with durable materials and precision engineering, this assembly also features a threaded spring seat for ride height tuning to help dial in desired lift and stance.
The remote reservoir increases oil capacity and cooling efficiency for consistent performance under sustained use, while the large-diameter shock body and quality coil spring help balance comfort and capability. This coilover kit is ideal for drivers looking to upgrade their suspension for both off-road excursions and on-road comfort.
✔ Position-sensitive damping for balanced on- and off-road performance
✔ Remote reservoir design for improved heat dissipation
✔ Threaded spring seat allows adjustable ride height
✔ Large piston and triple compression zones for control
✔ Durable construction resists wear and extends service life
🛠 Installation
- Install the coilover shock on the front left corner using factory mounting points and included hardware. Use the threaded spring seat to adjust ride height as desired before final tightening. After installation, a professional wheel alignment is recommended to ensure correct suspension geometry and optimal handling.
