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 loads.\u003c\/p\u003e\n\n\u003cp\u003eAs the spring compresses under load, the secondary stage engages, effectively mitigating excessive sag and enhancing overall stability. The manufacturing process is meticulously designed to maximize durability, offering robust corrosion resistance and sag prevention, ensuring longevity in demanding conditions.\u003c\/p\u003e\n\n\u003cp\u003eThese leaf springs are available in up to three distinct spring rate options for most applications, providing the flexibility to select the optimal 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.\u003c\/p\u003e\n\n\u003cp\u003eStandard 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.\u003c\/p\u003e\n\n\u003cp\u003eFor 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 configurations available for different setups: FS37-LH for the passenger side and FS37-RH for the driver side, as well as FS37H-LH and FS37H-RH for setups with steel bars and winches.\u003c\/p\u003e\n\n\u003cp\u003eWhen selecting springs, it is advisable to pair them with long travel shock absorbers to optimize performance.
