R4Tech Air Ride Suspension System

Firestone R4Tech Air Ride Systems are perfect for haulers and towers that want maximum performance and handling in any driving conditions, loaded or empty. The R4Tech senses when suspension sagging occurs under load and automatically compensates for it. It also improves the ride quality when empty or unloaded. This kit is equipped with air springs, softer leaf springs, custom valved Rancho RS9000 load-adaptive shocks, compressor, trailing links, J-Springs, hardware, fittings, air-line, and comprehensive instructions. These kits are designed specifically for your vehicle, ensuring a perfect fit and alignment without any drilling or modification. No special tools are required for installation.
