Suzuki Sierra (1974-5/1999) Leaf Spring 7/1974-5/1999 Tough Dog T62-LH Tough Dog Rear Leaf Spring
TD-T62-LH

Leaf springs represent one of the most enduring suspension designs in automotive history, maintaining their relevance in commercial vehicles due to their exceptional load-bearing capabilities. Engineered in Australia, these progressive rate leaf springs incorporate both primary and secondary stage leaves, ensuring that the vehicle's ride quality remains uncompromised under varying load conditions.

As the spring compresses under load, the secondary stage engages, effectively preventing excessive sag and maintaining optimal ride height. The manufacturing process is meticulously designed to maximize durability, offering robust corrosion resistance and sag prevention, ensuring longevity in demanding environments.

With up to three spring rate options available for most applications, these leaf springs provide the flexibility necessary to tailor the suspension setup to your specific vehicle requirements. Each spring is precision mandrel and die-formed, oil quenched, hardened, and tempered to guarantee extended service life.

Standard features include military wrap across all part numbers, accurate heat treatment, and construction from high-grade spring steel. Many applications also incorporate anti-friction pads to enhance performance. The springs are pre-stressed to maintain ride height and are rigorously load rate tested to ensure reliability.

For vehicles equipped with additional accessories, various spring rates are available to accommodate constant load scenarios. This includes fixed accessories such as canopies, steel trays, draw systems, fridges, toolboxes, rear bars, or spare wheel carriers, which are all considered constant loads.

Approximate raised height for these leaf springs ranges from 40-50mm, with specific models designated for light load applications: T62-LH for the passenger side and T62-RH for the driver side. It is advisable to select one of each to create a complete pair. Additionally, the installation of long travel shock absorbers is recommended when fitting raised springs to optimize performance.

Choosing the appropriate spring rate is crucial for achieving the best results in load carrying capacity, ride quality, and overall ride height. Please note that images provided are for representation purposes only and may not correspond directly to the specific part number being viewed.
