Please note: All suspension lift kits will come with recommended constant load springs to suit the vehicle. Refer to PDF for available options to suit the weight of accessories fitted to the vehicle.
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.
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.
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.
Dobinsons IMS monotube shock absorbers are designed for next level performance over twin tube shocks in those hot, harsh, demanding conditions. By utilising the monotube design, Dobinsons IMS shock absorbers can resist fade far longer on corrugated roads, long or hard working 4WD trips, towing or racing conditions.
The larger 50 and 60mm high flow pistons reduce internal pressures, reduce the heat generated, transfer heat to the body for faster cooling and offer improved damping performance and vehicle control at higher shaft speeds on rough terrain and during big impacts. Threaded bodies on struts allow for fine tuning of height and offer further improvements in cooling. The micro polished, hard chromed and heat treat shock shaft, CNC aluminium high flow race inspired piston, and DOM seamless tubing body provides the ultimate in performance and off-road durability.
