New Work-Rite™


Work-Rite Logo

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

R4Tech


R4Tech Logo

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.

Level-Rite™ Kits


Level-Rite logo

 

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.

 

Level-Rite Kit 
Level-Rite™ air spring & Dampers will:
  • Level the front end in variable load applications
  • Allow control of frontground clearance
  • Improve vehicle conttrol and stability
  • Reduce bottoming
  • Reduce suspension fatigue
