Mitsubishi Pajero (1983-1991) NA-NG Leaf Rear 7/1983-1991 Tough Dog FS021H Tough Dog Rear Leaf Spring
TD-FS021H

Leaf springs represent one of the most enduring suspension designs in automotive engineering, maintaining their relevance particularly in commercial vehicles due to their exceptional load-bearing capabilities.

Engineered in Australia, Tough Dog progressive rate leaf springs incorporate a sophisticated design featuring both primary and secondary stage leaves. This dual-stage configuration ensures that the vehicle's ride quality remains uncompromised under varying load conditions. As the spring compresses, the secondary stage engages to mitigate excessive sag, thereby enhancing overall performance.

The manufacturing process of these leaf springs is meticulously executed to guarantee maximum durability, corrosion resistance, and sag prevention. Tough Dog provides a selection of up to three spring rate options for most applications, allowing for tailored solutions that best fit your vehicle's specific setup.

Each spring is precision mandrel and die-formed, oil quenched, hardened, and tempered to ensure longevity and resilience. A military wrap is standard across all part numbers, and the springs are accurately heat-treated to optimize performance. Constructed from high-grade spring steel, these leaf springs also feature anti-friction pads in most applications, and are pre-stressed to maintain optimal ride height.

For those with additional accessories fitted to their vehicles, Tough Dog offers various spring rates to accommodate constant load carrying. This is particularly beneficial for vehicles equipped with fixed accessories such as canopies, steel trays, draw systems, fridges, toolboxes, rear bars, or spare wheel carriers.

Approximate raised height for these leaf springs ranges from 30-40mm, with specific models designed for different load capacities: FS021 for light loads (0-300kg) and FS021H for constant loads (300kg). It is advisable to pair these raised springs with long travel shock absorbers to achieve optimal performance.

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