Dobinsons Spring and Suspension™ proudly manufacture the highest quality replacement coil springs for many different applications to ISO9001:2008 international quality standards from their state of the art manufacturing facility in Central Queensland, Australia.
Dobinsons™ proudly boast one of the worlds largest range of coil springs including raised height and heavy duty 4wd springs, lowered performance passenger car springs, O.E. replacement springs and heavy duty springs for commercial vehicles.
As Dobinsons™ coil springs are manufactured in house, Dobinsons™ can manufacture smaller quantities and in most cases there are many different coil spring options available for your vehicle. This ensures the customer receives the best spring to suit their application and avoids a “One Size Fits All” scenario, especially important when selecting the correct spring rates and ride heights. When matched with a set of corresponding Dobinsons™ Heavy Duty Gas Shock Absorbers, Dobinsons™ can provide you with unrivalled performance and handling.
Start of the Art Heat Treatment
Heat treatment is unseen and is the most important steps in the coil spring manufacturing process. Hardening and tempering is completed by an extremely precise electronically controlled furnace to eliminate breakage and sagging.
Formed On Precision Mandrels
Each coil is precisely placed by a programmable logic computer to achieve perfect pitch. This is especially important in manufacturing variable and progressive rate springs.
High Intensity Shot Peening
All Dobinsons coils are shot peened to give longer life.
Precise End Configurations
Engineered coil ends are designed to fit directly into the original vehicle mounting points without any modification.
Spring Design engineers within Dobinsons Spring & Suspension™ utilize 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.
Powder Coat Finish
A durable powdercoat finish provides extreme protection against the elements
Fully Scragged & Load Tested
All coils are scragged 100% to eliminate subsequent spring sag and load tested to ensure that they meet and maintain the required specifications. Dobinsons alsoo perform spring fatigue testing and spring hardness testing using in-house state of the art testing equipment.
