S2RV Rear Suspension

Rear suspension not only defines ride and handling – it determines how much weight your motorhome can carry.



DetroitTM Rear Axles

19,000 – 21,000 lbs.

Detroit Axle

Backed by many years of manufacturing expertise, Detroitaxles provide market-leading performance and value. An integrated one-piece differential in these rear axles offer greater stability and durability, with a smaller ring gear size for reduced weight, but with the ability to carry more luxury amenities and belongings. Precision cut gears allow for a quieter axle and better gear mesh for driving comfort and durability.

Airliner® Air Ride

19,000 – 23,000 lbs.

Airliner® Air Ride's ingenious, no-maintenance design saves weight and operating costs while superbly cushioning you, your vehicle and your valuables.

  • Compared to steel suspensions, the AirLiner delivers greater comfort and, consequently, provides better handling and protection for your belongings.
  • Because the AirLiner suspension system has substantially fewer parts than competing systems, it offers greater reliability and needs less service in the long run.
  • AirLiner requires no lubrication, which means little or no routine maintenance.
  • AirLiner’s proven combination of trailing arm leaf springs and self-leveling, rolling-lobe air bags provides a uniformly soft spring ride, smoothing the ridges and filling the ruts like only a premium air suspension can.
  • The AirLiner is also designed to reduce sway when turning or negotiating curves, further providing superb ride and handling.

Elastomer bushings that insulate your driving experience.

Elastomer bushings ensure that the metal parts of the AirLiner suspension won’t rub together, resulting in a longer life. And since there’s no wear surface to lubricate or replace, the AirLiner's performance is never compromised—leading to a continued comfortable ride and a very comfortable operational cost.

A height-control valve that keeps drivelines in line.

To produce the relatively constant spring rate necessary for optimum cushioning performance, an air ride suspension must maintain a relatively constant ride height. AirLiner utilizes a premium rotary valve to fulfill this height-control function. Why a rotary-type valve? Because the efficiency of a conventional, rubber-seat valve can deteriorate with age, altering not only the spring rate but also the driveline angle, possibly shortening the driveshaft life.

Suspensions that aren’t afraid of the scale.

AirLiner air ride suspensions are lightweight champions. These suspensions are naturally lean because there are fewer parts to begin with. And they feature aluminum brackets on all but the 23,000-lb. models.
