Nissan Patrol (1988-1998) GQ Cab Chassis Leaf/Leaf 2/1988-1998 Tough Dog FS37-LH Tough Dog Front Leaf Spring
TD-FS37-LH

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, these progressive rate leaf springs incorporate both 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 meticulously engineered to guarantee maximum durability, corrosion resistance, and sag prevention, ensuring a long service life even under demanding conditions.

These leaf springs are available in up to three different spring rate options for most applications, providing the flexibility to select the most appropriate spring rate tailored to your vehicle's specific setup. Each spring is precision mandrel and die-formed, oil quenched, hardened, and tempered to ensure longevity and performance.

Standard features include military wrap across all part numbers, accurate heat treatment, and construction from high-grade spring steel. Many applications also include 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 to 50mm, with specific models designed for different configurations: FS37-LH for the passenger side, FS37-RH for the driver side, FS37H-LH for vehicles with a steel bar and winch on the passenger side, and FS37H-RH for the driver side.

When selecting your springs, please note that LH and RH designations indicate the left-hand and right-hand sides, respectively, and it is advisable to select one of each to create a complete pair. Additionally, it is recommended to pair these raised springs with long travel shock absorbers to optimize performance.
