Overview
Firestone R4Tech Suspension System
Big rig trucks use air suspension for a reason. Airide™ suspensions ride better than steel spring suspensions, reduce the wear and tear on your equipment and 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, the axle control of a leaf spring and the ease of installation of a standard leaf spring and Ride-Rite kit.
The foundation R4Tech suspension is designed and manufactured by SANLUIS Rassini, the preeminent supplier of leaf springs to the North American light truck industry. When combined with Firestone Airide™ air springs and Ride-Rite™ air
accessories, the result is R4Tech, a suspension kit that is unmatched in terms of durability, reliability and ride quality.
Each application is carefully designed and tuned to improve the ride quality and handling performance of the factory vehicle.
Kit includes everything for a installation:
- Air springs
- Leaf springs
- J-Springs
- Load adaptive shocks
- Air compressor and tank
- All necessary hardware
- Comprehensive Instructions
Features & Benefits
Firestone R4Tech Suspension Kits will:
Impove the ride:
Air springs and softer-rated leaf springs mean improved ride across all conditions, especially unloaded.
Improve handling:
The shocks included in the kit automatically adjust to load to optimize ride quality and handling stability. The shocks included in the kit vary their stiffness based on the air spring pressure. The Firestone dampers for R4Tech adjust to the load, optimizing the ride in all conditions.
Kneel and level:
Allows for easier loading and trailer attachment with the kneel feature. The air springs automatically adjust for any load, keeping your vehicle level.
Control axle hop and windup:
R4Tech utilizes the patented lower link and “J-spring”. These components stop axle windup, reducing brake hop and axleshudder under heavily loaded acceleration.
