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.\u003c\/p\u003e\n\n\u003cp\u003eAs 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.\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 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.\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 40-50mm, with specific models designed for different load capacities:\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003eBP-019 - 0-200kg Light Load\u003c\/li\u003e\n\u003cli\u003eFS781-LH - 400kg Constant Load Passenger Side\u003c\/li\u003e\n\u003cli\u003eFS781-RH - 400kg Constant Load Driver Side\u003c\/li\u003e\n\u003cli\u003eFS781HM-LH - 300kg Constant Load Passenger Side\u003c\/li\u003e\n\u003cli\u003eFS781HM-RH - 300kg Constant Load Driver Side\u003c\/li\u003e\n\u003cli\u003eFS781XHD-LH - 900kg Constant Load Passenger Side\u003c\/li\u003e\n\u003cli\u003eFS781XHD-RH - 900kg Constant Load Driver Side\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eIt is advisable to pair these raised springs with long travel shock absorbers for optimal performance.
