Holden Jackaroo (1981-1986) 11/1981-1986 Tough Dog FS113H Rear Raised Leaf Spring
TD-FS113H

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 classified as constant loads.

It is crucial to select the appropriate spring rate to achieve optimal results in load carrying capacity, ride quality, and ride height. The approximate raised height provided by these springs ranges from 40-50mm, with specific models designed for different load capacities: FS113 for light loads (0-300kg) and FS113H for constant loads (300kg).

For best performance, it is recommended to pair these raised springs with long travel shock absorbers. Please note that the images provided are for representation purposes only and may not correspond to the specific part number being viewed.
