Corgrit — The Firestone Coil-Rite Rear Air Spring Kit gives the Lexus LX 570 adjustable suspension support to accommodate changing passenger and cargo loads. Polyurethane air springs deliver additional support when loaded while maintaining a more compliant spring rate during lighter-load driving. With individual manual inflation valves and a no-drill installation, the system helps improve vehicle stability, maintain ride height, and deliver more controlled handling across a range of driving conditions.

Key Features

• Provides Up to 1,000 Pounds of Supplemental Load Capacity
• Variable Air Spring Rate Adapts to Changing Vehicle Loads
• Independent Inflation Helps Maintain Balanced Suspension Support
• No-Drill System Installation Within Factory Rear Coil Springs

Air Spring Kit Specifications

The Firestone Coil-Rite system uses two elastic polyurethane air springs installed inside the factory rear coil springs. Adjustable air pressure provides a variable spring rate, increasing suspension support under heavier loads while preserving a softer response when the vehicle is unloaded.

Overview

The Coil-Rite kit is engineered to enhance the rear suspension with adjustable support for changing vehicle loads. Installed directly inside the factory coil springs, the system adds control without replacing the factory springs. Whether carrying passengers or heavier equipment, the adjustable springs help maintain a balanced stance and more composed handling.

Support

The Coil-Rite system adapts its support to the vehicle's load. Increased air pressure produces a higher effective spring rate to help support additional weight, while reduced pressure allows a softer response during unloaded driving.

Stability

Each air spring can be adjusted independently, providing greater control when cargo is unevenly distributed. Balanced rear suspension support reduces body roll and improves vehicle stability, particularly when cornering or hauling.

Performance

The air springs support more consistent handling and braking when the vehicle is loaded. Maintaining proper ride height also helps keep headlight beams aligned and can reduce tire wear associated with an imbalanced suspension.

Installation

The air springs install within the existing rear coil springs, supplementing the factory suspension. A no-drill installation keeps modifications to a minimum while providing an effective way to add adjustable rear suspension support.
