LEAF SPRINGS

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

Design

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.

Manufacturing Process

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.

Multiple Options

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.

Military Wrappers

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.
