Description
Product Overview
The Firestone Airide 0335 rear air spring is a precision‑engineered component designed to replace the original air springs in Firestone Ride‑Rite suspension kits. Constructed with a double‑convoluted steel bead plate architecture, the spring offers superior burst strength and resilience against bottom‑out damage. Its compact dimensions of 9 × 9 × 6 inches and a weight of just over 5 pounds make it an ideal fit for a wide range of rear suspension locations. The spring connects via a 1/4″ NPT fitting, allowing it to operate at pressures up to 100 psi, which translates into consistent load‑leveling performance across a variety of driving conditions. Whether you are hauling a trailer, a camper, or heavy cargo, this air spring helps maintain vehicle stability, reduces tire wear, and improves overall ride comfort. The product is manufactured by Firestone under the Airide brand, ensuring that each unit meets rigorous quality standards and is backed by a reputable warranty program.

Usage
This rear air spring is suited for a broad spectrum of applications, from light‑duty pickups to heavy‑duty trucks that regularly tow or carry substantial payloads. It integrates seamlessly with existing Ride‑Rite kits such as models 1130, 2029, 2040, 2065, 2068, 2085, and 2070, making it a versatile upgrade for owners seeking to restore or enhance their suspension performance. In everyday driving, the spring works to level the chassis, preventing sagging of the leaf springs when the vehicle is loaded. For off‑road enthusiasts, the air spring absorbs shocks from uneven terrain, delivering a smoother ride and protecting the underlying suspension components from premature wear. Commercial fleet operators will appreciate the durability and corrosion‑resistant finish, which extends service life even in harsh environments. Installation is straightforward for technicians familiar with air‑suspension systems, requiring only the removal of the old spring, connection of the 1/4″ NPT fitting, and adjustment of air pressure to the desired level.
