With serious 4×4 owners now pushing their vehicles through harder, harsher terrain with more accessories fitted to their 4×4’s than ever before Dobinsons saw the need for a no compromise, performance engineered suspension that offers the ultimate in performance.
Coil Springs
Spring Design engineers within Dobinsons Spring & Suspension™ utilise the latest coil spring design programs to ensure each spring will meet and exceed the design requirements and achieve the maximum working life. These state-of-the-art design programs are crucial when designing variable/progressive rate springs to ensure laden and unladen spring rates are correct to provide the best possible ride comfort and handling.
Heat treatment is one of the most important steps in the coil spring manufacturing process. All Dobinsons coil springs are ‘hot wound’ and the hardening and tempering of our coil springs is completed by an extremely precise electronically controlled furnace to eliminate breakage and sagging.
Each coil spring is precisely wound by a programmable logic computer to achieve perfect pitch. This precision is extremely important when manufacturing variable and progressive rate coil springs. All Dobinsons™ coils springs are shot peened to increase durability and dramatically reduce fatigue.
Engineered coil ends are designed to fit directly into the original vehicle mounting points without any modification. All Dobinsons™ coil springs are load tested and scragged 100% to eliminate subsequent spring sag, and ensure they meet and maintain the required specifications. We also perform spring fatigue and hardness testing using in-house state of the art testing equipment.
A durable powder coat finish provides extreme protection against the elements.
Shock Absorbers
Dobinsons Twin Tube Nitrogen Gas charged shock absorbers are made from the world’s highest quality external and internal parts sourced worldwide. They provide a significant increase in performance over the standard shock absorbers.
Originally equipped shock absorbers are prone to shock fade and when a vehicle is loaded simply cannot cope with the additional weight and the harsh condition that 4X4 owners love to put them through. Dobinsons twin tube shock absorbers feature larger bodies, larger bores and increased valving performance to dramatically improve vehicle handling and control and reduces shock fade.
Each shock absorber is filled with high quality Hi-Temperature shock absorber oil then filled with low pressure nitrogen gas to pressurize the oil and assists in reducing oil aeration commonly known as Shock Fade.
