Dobinsons™ leaf springs are manufactured using only the highest quality raw materials. The company understands the importance of choosing not only the best-grade steel, but also the right level of processing to ensure maximum durability under extreme loads. Dobinsons engineers design each spring specifically for the vehicle model, considering load and lift requirements. The design includes tapered and thinned leaf ends for even stress distribution across the spring, resulting in optimal handling both loaded and unloaded. Carefully selected leaf lengths and thicknesses maximize durability, comfort, and load-carrying capacity.
Dobinsons' 4×4 heavy-duty suspensions have been tested in the harshest conditions around the world, repeatedly proving their exceptional performance over the decades.
Experience, quality, safety, and comfort – this is what UNION 4x4 offers through the DOBINSONS suspension range.
