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.Motorhomes that carry heavy payloads can benifit from having the semi air kit fitted. 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.
