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.
Built on Pride, Developed with Technology
Dobinsons manufactures and repairs a large range of springs and sells a comprehensive range of suspension components for 4×4 Vehicles. Dobinsons stocks 13,000 spring and suspension specifications on hand, these recommendations should be used as a guide only and more consultation should be given.
Dobinsons Spring and Suspension’s range of heavy duty 4wd torsion bars are manufactured from high quality micro alloy steel with a thicker bar diameter than the original vehicle torsion bars to improve performance when accessories are fitted. When vehicles are fitted with additional accessories such as steel bullbars, winches, dual battery kits and other frontal accessories the weight placed on the torsion bars can be dramatically increased.
With over 60 years of experience manufacturing in Australia, Dobinsons Spring & Suspension™ are no strangers to providing the highest quality spring and suspension components, and our range of leaf springs are no exception.
Our range includes raised and heavy duty leaf springs for 4x4’s, heavy duty and parabolic replacement leaf springs for trucks and commercial vehicles, plus raised and replacement leaf springs for 4×2 utilities and passenger vehicles. In most cases there are multiple options available to ensure the correct leaf spring is available to meet most requirements.
Dobinsons™ leaf springs are manufactured from only the highest quality raw materials. We understand the importance of selecting not only the highest quality spring steel, but also the correct grade that will give the longest life under the harshest conditions.
Our design engineers ensure that all our leaf springs are designed specifically for each vehicle model, with consideration given to the load and height requirements for each application. Design is one of the most important stages in the leaf spring manufacturing process, and with over 60 years of design and manufacturing experience, we recognise the importance of this.
Design features include Drawn, tapered and thinned leaf ends for even stress distribution over the entire spring pack, two stage spring design for the rear of most vehicles to achieve optimum ride and handling both laden and unladen and carefully selected leaf lengths and thickness’s to maximize the spring life, comfort, load carrying capacity, wheel travel and performance.
Each stage of the Dobinsons™ leaf spring manufacturing process is vital to ensure the complete spring pack will out perform our competitors products. Manufactured to international quality standards ISO9001:2008 using premium grade Sup 9 silicon manganese spring steel, Dobinsons™ range of leaf springs are made to world leading quality standards.
For most vehicles, we offer multiple options to best suit customer needs, this ensures the correct spring rate is matched for the vehicle model and the accessories added. This provides a raised height where applicable without going beyond the safe design requirements to enhance performance, load carrying capacity and off-road ability without compromising safety.
Where possible Dobinsons leaf springs utilize full military wrappers and full length wrappers to provide additional support to the main leaf and improve safety. Anti-Friction inter leaf liners are use to reduce the friction at each leaf end where the load is greates and provides a smoother, quieter ride.
Dobinsons leaf springs feature high strength alignment clips with nylon insulators to reduce wear and noise. Nyloc nuts are also featured on bolted clips to prevent loosening off nuts which can cause tyre damage.
Each Dobinsons leaf spring is shotpeened on the tension side of each life and completely scragged. This dramatically reduces the chance of sagging and breakage and doubles the expected working life of the spring. Random sampling from production is then also durability tested to ensure Dobinsons leaf springs will outlast the competitors.
Twin Tube Nitrogas Shock Absorbers
Designed, developed and tested in Australia by Dobinsons Spring & Suspension, in house suspension design engineers, Dobinsons 4×4 shock absorbers are designed and tested to perform in the harshest conditions right across the world.
As Dobinsons Spring and Suspension export to over 40 countries worldwide from their Australian head office, the importance of quality is at the forefront in the complete design and manufacturing process. This ensures every shock can withstand the blistering heat and corrugations of the Australian outback right through to the subzero temperatures of a Russian winter.
