Features:

Fast, low cost installation: Few chassis modifications are required in the installation of Reyco Granning AirGlide® systems. Even the OEM chassis manufacturer's axle clamp group and front spring hanger are reused. So, vehicle manufacturers report many advantages, including: The time required to install an AirGlide® is about one-half of that required to install a competitive air suspension system.      Elimination of axle misalignment caused by altering the position of the axle clamp assembly during suspension system installation. Elimination of axle weaknesses associated with changes in the metallurgical structure of the axle material during the welding operations required to install most competitive air suspension systems. The shock absorbers provided with the chassis may be used to further reduce the cost of installation. The rub block and tower design eliminates the need for track bars as they limit lateral float of the axle. The rub block provides a self-cleaning, no-maintenance wear surface for the axle tower-to-chassis frame contact. A polyester retaining strap prevents over-extension of the shocks and air springs. NOTE: AirGlide® suspension models are engineered for application with specific chassis. Each suspension is shipped with assembly instructions and mounting hole template to ensure rapid, easy installation. Maintains designed vehicle ride height: AirGlide® suspensions ensure front-to-rear vehicle ride height consistency regardless of the distribution of the load within the vehicle. A standard height control valve directs appropriate pressure to the air springs. Superior roll stiffness: Unlike competitive suspension designs which weaken with age and wear, an AirGlide® maintains roll stiffness. This advantage is due to two unique Reyco Granning suspension design features: First, AirGlide's® time-proven, spring-beam suspension design serves a dual function. It provides vertical axle float as it helps to absorb shock loads. In addition, because the two spring beams are solidly attached to the axle, they function as counterbending beams to limit the extent the chassis may lean. Consistent air springs: The time-prove, step-down, spring-beam design is used extensively in heavy truck suspensions. For light and medium truck air suspension systems, it facilitates the use of the original mechanical suspension mounting points to reduce the cost of installation. The front spring hanger is used to attach the front end of the AirGlide® suspension. Proven spring-beam design: AirGlide's® air springs provide constant spring characteristics. And the simplicity of design of the air spring pedestal promotes easy installation and service.   Applications: Click Part Number to obtain pricing and to order online.
