Toyota Landcruiser (1984-1999) 75 Series 11/1984-1999 Tough Dog T52 Tough Dog Front Leaf Spring
TD-T52

Leaf springs represent one of the most enduring suspension designs in automotive engineering, maintaining their relevance in commercial vehicles due to their exceptional load-bearing capabilities. Designed in Australia, Tough Dog 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 engineered to maximize durability, offering robust corrosion resistance and sag prevention, ensuring longevity in demanding environments.

Tough Dog provides a selection of up to three spring rate options for most applications, allowing for tailored performance to suit specific vehicle setups. Each spring is precision mandrel and die-formed, oil quenched, hardened, and tempered to guarantee extended service life. The military wrap design is standard across all part numbers, enhancing structural integrity.

These leaf springs undergo accurate heat treatment and are crafted from high-grade spring steel, ensuring superior performance. Many applications feature anti-friction pads to reduce wear and enhance ride quality. Each spring is pre-stressed to maintain ride height and is rigorously load rate tested to meet demanding standards.

For vehicles equipped with additional accessories, Tough Dog offers various spring rates to accommodate constant load carrying requirements. The approximate raised height provided by these springs ranges from 40 to 50mm, with specific configurations such as T52 designed for up to steel bar loads and T52H for steel bar and winch setups.

It is advisable to pair these raised springs with long travel shock absorbers to optimize performance and handling characteristics. Please note that images provided are for representation purposes only and may not reflect the exact part number being viewed.
