Air Spring Kit Specifications

The Firestone Coil-Rite rear air spring system supplements the Sequoia's factory rear coil springs with manually adjustable air support. Its variable spring rate provides increased resistance under heavier loads while allowing a more compliant response when the vehicle is lightly loaded.

Overview

This kit gives the 3rd-Gen Sequoia an adjustable solution for managing additional rear weight. Installed within the factory coil springs, the air springs supplement the suspension to help support passengers, luggage, and equipment. Manual pressure adjustments let drivers adapt to different loads while maintaining a balanced and controlled ride.

Support

When added weight compresses the rear suspension, the air springs provide supplemental resistance to help limit sag. This helps maintain a level stance and improves suspension control when the Sequoia is carrying a heavier load.

Adjustability

The system uses air pressure to change the spring response according to vehicle weight. Increased inflation provides firmer support under heavier conditions, while reduced pressure allows a softer response during lighter driving.

Control

Each air spring can be adjusted using a standard air source. Adding or releasing air follows the same process as inflating a tire, giving drivers convenient control over suspension firmness without an onboard compressor or electronics.

Installation

The air springs fit inside the factory rear coil springs without requiring drilled mounting points. Supplied air hoses, inflation valves, and hardware provide the components needed to integrate the system with the existing suspension.
