Firestone Industrial and Sanluis Rassini Introduce R4Tech Hybrid Air Suspension

Firestone Industrial Products Company, LLC introduces the new R4Tech(tm), a hybrid air/leaf suspension system featuring Firestone Ride-Rite(tm) air spring and SANLUIS Rassini(r) suspension technologies.
 
R4Tech, which replaces the factory leaf spring suspension, comprises a high-quality Firestone air spring and SANLUIS Rassini's leaf-spring suspension, positioned in a unique architecture to create a fully functional system that adjusts for varying load capacities.  The suspension system delivers an improved ride at all times by utilizing the variable spring rate of the air spring to stiffen when the truck is loaded and soften when unloaded.

An upgrade over traditional solutions, R4Tech increases axle control during acceleration and braking for improved torque management and reduced wheel hop.  The design allows the suspension to move at all load conditions, therefore isolating and absorbing road impact for passengers and cargo alike.  Plus, less steel in the system reduces weight in the vehicle and improves fuel economy.
 
"By combining Firestone's knowledge and resources as the 'World's No. 1 Air Spring(tm)' - including air suspension technology, air spring design, tech support, marketing and distribution - and Rassini's expertise in suspension systems, we have developed a premier suspension system that reduces the impact of the road on passengers, cargo and trailers," said Paul Fessel, automotive OE sales manager, Firestone Industrial Products Company.  "R4Tech is ideal for enthusiasts hauling their thoroughbred horses, race cars or any other type of trailer because it helps prevent damage to important cargo."
 
The complete R4Tech system comes with the Rassini foundation suspension - including leaf plates, lower trailing link, J-spring, spring perches and mounting brackets - the Airide(tm) air spring and an air compressor control system that maintains the proper air level in the spring for the exact load you're carrying.  Professional installation is recommended.
