As market leaders in the specialist field of air suspension, Glide-Rite Products have developed a low-cost Semi-Air system to assist the existing steel suspension. Based on the design principle of Glide-Rite’s widely acclaimed full air suspension, Semi-Air utilises the latest technology to enable you to achieve the optimum chassis ride height, regardless of payload. With standard steel suspension, the ride height of a vehicle will alter significantly between laden and unladen conditions, a factor which can lead to instability and ground clearance problems, particularly under heavy loading. However, Semi-Air from Glide-Rite works with the existing steel sprung suspension by providing extra regulated support to ensure that the vehicle remains at a constant ride height regardless of payload. By using Semi-Air you not only prevent the rear of the vehicle sagging, but also increase the stability and handling, particularly when fully laden. Semi-Air utilises bespoke air bags mounted between the existing leaf springs and the vehicle chassis. As the load fluctuates, the pressure in the air-bags varies proportionally, to maintain the optimum chassis position. Glide-Rite suspension systems are available for a wide range of vehicles. All systems come with a comprehensive warranty as standard and with the support of a network of highly trained technicians.
