Air Spring Kit Specifications

Designed to work with the factory rear coil springs, the Coil-Rite system adds adjustable air-assisted support to the RAV4's existing suspension. Its variable spring rate provides increased resistance when carrying heavier loads and a softer response when the vehicle is lightly loaded.

Overview

This air spring kit adds load-responsive suspension support to the 4th-Gen RAV4. By fitting inside the factory rear coil springs, the air springs help the vehicle better manage weight changes from passengers, luggage, and other cargo. The adjustable design improves rear suspension control while keeping the original coil spring setup.

Balance

The Coil-Rite air springs provide supplemental support to help limit excessive sag, keeping the RAV4 more level when carrying heavier loads. A more balanced stance can also contribute to improved handling and braking response.

Response

The Coil-Rite air springs adjust their spring response based on the applied air pressure. Increased pressure provides a firmer response when the vehicle is loaded, while reduced pressure allows a softer response during lighter use.

Adjustability

Each air spring has its own inflation valve, allowing pressure to be adjusted independently with a standard air source. giving owners a straightforward way to adjust suspension support before carrying additional cargo or passengers.

Installation

The air springs fit within the existing rear coil springs, and a no-drill installation avoids the need for new mounting holes. The included air hoses, individual inflation valves, and hardware provide the components required for the system.
