Nissan Navara (2005-2015) D40 2.5L; 4.0L 12/2005-2015 Tough Dog T85LL Tough Dog Rear Leaf Spring
TD-T85LL

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 distinct 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. The approximate raised height achieved with these springs ranges from 30-40mm, with specific ratings as follows: T85C for light loads (0-300kg), T85L for constant loads (300kg), and T85LL for heavier constant loads (500kg).

It is advisable to pair these raised springs with long travel shock absorbers to optimize performance. Constant load refers to weight that is permanently added to the vehicle, such as fixed accessories like canopies, steel trays, draw systems, fridges, toolboxes, rear bars, or spare wheel carriers. Selecting the appropriate spring rate is crucial for achieving the best balance of load carrying capacity, ride quality, and ride height.
