What is the benefit of a piggyback reservoir?

The piggyback reservoir holds extra shock oil, which helps to keep the shock cooler during extended use or under heavy loads. This improved cooling helps maintain consistent damping performance and can extend the life of the shock.

How do I adjust the shocks?

These shocks feature an external adjuster knob on the reservoir. You can turn this knob to change the damping settings, allowing you to fine-tune the ride stiffness and control to better suit different driving conditions or preferences.

Does this kit include everything needed for installation?

This kit includes a pair of rear shock absorbers with piggyback reservoirs and adjusters. It is recommended to consult the manufacturer's installation instructions for any additional hardware or specific procedures required for your vehicle.
