5. Installation Guide

The ECCPP Rear Coil Springs are designed for direct fitment, ensuring performance equivalent to the original springs on your vehicle. While these springs are designed for straightforward replacement, professional installation is strongly recommended due to the specialized tools and safety procedures required for suspension work.

5.1 General Installation Considerations

• Vehicle Preparation: Safely lift and support the vehicle using appropriate lifting equipment and jack stands. Remove the wheels.
• Component Removal: Carefully remove the existing rear coil springs. This typically involves disconnecting lower control arms or other suspension links to allow the axle to drop sufficiently.
• Spring Placement: Install the new ECCPP coil springs in the original spring installation position. These springs are designed to integrate without requiring replacement of the shocks.
• Reassembly: Reconnect all suspension components, ensuring all bolts are torqued to the vehicle manufacturer's specifications.
• Final Checks: Lower the vehicle, re-install wheels, and perform a final inspection to ensure all components are secure and functioning correctly.
