The progressive load deflection characteristics of the new Work-Rite kit will smooth your ride when your vehicle is fully loaded, and won’t compromise your ride when it’s not.

These load assist springs are injection-molded, and are made of microcellular urethane. They do not use air like the Ride-Rite family of springs so there is no air pressure to monitor. Work-Rite load assist springs are made of a base polymer developed specifically for the automotive environment with low temperature flexibility and a high repeated compression resistance. They are adjustable for individual loading scenarios using spacers provided in each kit.

There are six separate spring-geometry and stiffness combinations for several applications for light duty trucks, vans, and SUVs. Most work-Rite kits are a no-drill design, which means they use the existing holes in the frame for installation and require only simple hand tools.

The Work-Rite load assist springs are maintenance-free with a limited lifetime spring warranty and provide a more comfortable, safer ride for you and your cargo

Big trucks use air suspension for a reason. Airide™ suspensions ride better than steel spring suspensions, and reduce the wear and tear on your equipment. They protect both the driver and cargo, regardless of the load.

R4Tech is a patented, hybrid air-over-leaf suspension that provides the ride quality of a full-air suspension with the ease of installation of a standard leaf spring and Ride-Rite™ kit.

The foundation of the R4Tech suspension is designed and manufactured by SANLUIS Rassini, the preeminent supplier of springs to the North American light truck industry. When combined with Firestone Airide™ air springs and Ride-Rite™ air accessories, the result is a suspension kit that is unmatched in terms of durability, reliability, and ride quality.

Ride-Rite™ air helper springs mount between the frame and the suspension of light-trucks, vans, and motorhomes. The heavy-duty convoluted air springs will handle all leveling needs with load carrying capacities between 3,200-5,000 lbs per set*.

Ride-Rite™ air helper springs will:

*Do Not Exceed The Vehicle's Recommended Gross Vehicle Weight Rating (GVWR)

Coil-Rite™ air helper springs mount inside an existing open coil spring suspension. These air springs provide adjustable spring rates far superior to the standard coil spring. The durable polyurethane air springs will support 500-1,000 lbs per set*. 

Coil-Rite™ air helper springs are made of durable polyurethane to withstand the rigors of coil-sprung suspensions.

*Do Not Exceed The Vehicle's Recommended Gross Vehicle Weight Rating (GVWR)

Why use a Firestone Air-Rite™ system?

• Instant adjustability of your air helper springs
• Increased life of the air helper springs
• Continous monitoring of the suspension
• Convenience

 

Certain factory suspension configurations do not allow the fitment of a stand-alone air spring. In these cases, it is necessary to pair the air spring with the shock absorber to achieve meaningful load capability while maintaining a hassle-free installation. For these applications, Firestone has designed a fully-protected, reversible sleeve air spring and paired it with a high-performance Bilstein monotube shock absorber for perfectly matched performance characteristics over the entire operating spectrum.
