SuperSprings leaf spring helpers are easily and quickly installed directly above the vehicle’s rear leaf springs. They work in parallel with the vehicle’s existing suspension system and kick-in on demand. The increased spring-rate produced by installing SuperSprings helps eliminate vehicle rear-end sag and improves towing capabilities. The unique anti-sway properties of SuperSprings assist springs reduce body roll, providing enhanced driver safety and control. These features are most noticeable when cornering, encountering strong cross winds, or dealing with wind buffeting from other traffic.

Features include:
Injection-molded microcellular urethane
Base polymer developed specifically for the automotive environment
Low temperature flexibility to -63°C
High-repeated compression resistance
Progressive load-deflection characteristics for smooth ride quality
6 separate spring-geometry and stiffness combinations (not a one-size-fits-all solution)
Most Work-Rite kits are a no-drill design
Air Lift AirCellThe Air Lift AirCell, a microcellular urethane spring, is a lower cost, no-maintenance product to reduce sag and improve ride in constantly loaded vehicles. Easy to install, most AirCell springs mount between the frame and axle/spring in place of a jounce bumper. They provide a better ride than rubber load supports or steel overload springs and are half the cost of most steel overload springs. Tough and long-lasting, AirCell springs are made from the same rugged material as factory jounce bumpers.
AirCell is engineered by Air Lift, the air suspension leader, especially for vehicles that maintain constant loads such as work trucks, fleet, and delivery vehicles. They're great for anyone whose truck is always loaded and wants load support and ride quality at a very affordable price. Rear kits keep heavily-loaded pickups level and greatly improve ride, while front kits provide support for trucks with snow plows or other heavy front equipment.
