With over 60 years of experience manufacturing in Australia, Dobinsons Spring and Suspension are no strangers to providing only the highest quality spring and suspension components, and Dobinsons range of leaf springs are no exception. Dobinsons range of leaf springs include raised and heavy duty leaf springs for 4wd’s, heavy duty and parabolic replacement springs for trucks and commercial vehicles and raised and replacement springs for 4×2 utilities and passenger vehicles. In most cases there are multiple options available to ensure the correct spring is available to meet each customers requirements. Manufactured to international quality standards ISO9001:2008 and TS 16949 using premium grade Sup 9 silicon manganese spring steel, Dobinsons range of leaf springs are made to world leading quality standards.
High Quality Spring Steel
Dobinsons leaf springs are manufactured from only the highest quality raw materials. With over 60 years of experience Dobinsons understand the importance of selecting not only the highest quality spring steel but the correct grade that will give the longest life under the harshest conditions
Dobinsons design engineers ensure that every spring is designed specifically for the vehicle, load and height requirements for each application. The spring design is the most important step in manufacturing a leaf spring and with over 60 years designing and manufacturing, Dobinsons understand the importance of this. Design features include Drawn, tapered and thinned leaf ends for even stress distribution over the entire spring pack, 2 stage spring design for the rear of most vehicles to acheive 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 step of the manufacturing process of Dobinsons leaf springs is vital to ensure the complete spring pack will outperform the competitors. Each spring is manufactured to international quality standards ISO9001:208 and TS 16949.
For most vehicles Dobinsons offer multiple options to best suit the customers need. This ensures the correct spring rate is matched for the vehicle and accessories added, and provides a raised height where applicable without going beyond the safe design requirements to enhance performance, load carrying capacity and offroad 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
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.
High Strength Alignment Clips
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.
Shotpeend and Scragged
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.
