Toyota Landcruiser (1999-On) 78 79 Series Single Cab 10/1999-On Tough Dog FS781-LH Tough Dog Rear Leaf Spring
TD-FS781-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 are meticulously crafted with primary and secondary stage leaves, ensuring that the vehicle's ride quality remains uncompromised under varying loads.

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

These leaf springs are available in up to three distinct spring rate options for most applications, providing the flexibility to select the ideal spring rate tailored to your vehicle's specific setup. 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 carrying. The approximate raised height provided by these springs ranges from 40-50mm, with specific models designed for different load capacities:

• BP-019 - 0-200kg Light Load
• FS781-LH - 400kg Constant Load Passenger Side
• FS781-RH - 400kg Constant Load Driver Side
• FS781HM-LH - 300kg Constant Load Passenger Side
• FS781HM-RH - 300kg Constant Load Driver Side
• FS781XHD-LH - 900kg Constant Load Passenger Side
• FS781XHD-RH - 900kg Constant Load Driver Side

It is advisable to pair these raised springs with long travel shock absorbers for optimal performance. When selecting LH and RH models, ensure to choose one of each to create a complete set. The term "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.

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 accurately depict the specific part number being viewed.

Important Notes

• We recommend fitting long travel shock absorbers with raised springs.
• Where LH and RH are noted select one of each to create a pair.
• Constant Load refers to weight that is added to the vehicle and will remain in/on the vehicle at all times.
• Fixed accessories such as a canopy, steel tray, draw system, fridge, tool boxes, rear bar or spare wheel carrier are considered Constant Load.
• It is important to select the most relevant spring rate to achieve the best results for load carrying, ride quality and ride height.
