Anti-friction Inter Leaf Liners

Anti-Friction inter leaf liners are use to reduce the frictionat each leaf end where the load is greates and provides asmoother, quieter ride.

Shotpeend & 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.

Manufacturing Process

Each stage of the Dobinsons leaf spring manufacturing process is vital to ensure the complete spring pack will out perform our competitors products.

4x4 U-bolts are made from high quality, 10.9 grade high tensile steel and supplied with hardened deep nuts for maximum clamping pressure and reliability. It is recommended that when replacing leaf springs that new u-bolts are fitted.
