As the spring compresses, the secondary stage engages to mitigate excessive sag, providing a balanced ride.\u003c\/p\u003e\n\u003cp\u003eThe manufacturing process is meticulously designed to maximize durability, offering robust corrosion resistance and sag prevention. Tough Dog provides a selection of up to three spring rate options for most applications, allowing for tailored performance based on your vehicle's specific setup.\u003c\/p\u003e\n\u003cp\u003eThese leaf springs are precision mandrel and die-formed, oil quenched, hardened, and tempered to ensure longevity. A military wrap is standard across all part numbers, and each spring is accurately heat-treated to enhance performance. Constructed from high-grade spring steel, many applications feature anti-friction pads to reduce wear and improve efficiency.\u003c\/p\u003e\n\u003cp\u003ePre-stressing the springs helps maintain optimal ride height, while diamond cut ends enhance the overall performance. Load rate testing ensures that each spring meets rigorous standards for strength and reliability.\u003c\/p\u003e\n\u003cp\u003eFor vehicles equipped with additional accessories, Tough Dog offers various spring rates to accommodate constant loads. This includes fixed accessories such as canopies, steel trays, draw systems, fridges, toolboxes, rear bars, or spare wheel carriers, which are all classified as constant loads.\u003c\/p\u003e\n\u003cp\u003eIt 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 30-40mm, with specific models catering to different load requirements: BPN-008 for light loads (0-300kg) and BPN-008H for constant loads (300kg).\u003c\/p\u003e\n\u003cp\u003eFor enhanced performance, it is advisable to pair raised springs with long travel shock absorbers, ensuring that your vehicle handles the increased height and load effectively.\u003c\/p\u003e\n\u003cp\u003ePlease note that images provided are for representation purposes only and may not correspond directly to the specific part number being viewed.\u003c\/p\u003e\u003ch4\u003eFeatures of Tough Dog Leaf Springs\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eDesigned in Australia\u003c\/li\u003e\n\u003cli\u003eProgressive rate leaf springs\u003c\/li\u003e\n\u003cli\u003ePrimary and secondary stage leaves\u003c\/li\u003e\n\u003cli\u003ePrevents excessive sag under load\u003c\/li\u003e\n\u003cli\u003eMaximum life and corrosion protection\u003c\/li\u003e\n\u003cli\u003eUp to 3 spring rate options\u003c\/li\u003e\n\u003cli\u003ePrecision mandrel \u0026amp; die-formed\u003c\/li\u003e\n\u003cli\u003eOil quenched, hardened \u0026amp; tempered\u003c\/li\u003e\n\u003cli\u003eMilitary wrap standard\u003c\/li\u003e\n\u003cli\u003eAccurately heat-treated\u003c\/li\u003e\n\u003cli\u003eManufactured from high grade spring steel\u003c\/li\u003e\n\u003cli\u003eAnti-friction pads in most applications\u003c\/li\u003e\n\u003cli\u003ePre-stressed to maintain ride height\u003c\/li\u003e\n\u003cli\u003eDiamond cut ends\u003c\/li\u003e\n\u003cli\u003eLoad rate tested\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eSpring Rate Options\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eBPN-008 - 0-300kg Light Load\u003c\/li\u003e\n\u003cli\u003eBPN-008H - 300kg Constant Load\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eImportant Notes\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eRecommend fitting long travel shock absorbers with raised springs\u003c\/li\u003e\n\u003cli\u003eConstant Load refers to weight that remains in\/on the vehicle\u003c\/li\u003e\n\u003cli\u003eFixed accessories considered as Constant Load\u003c\/li\u003e\n\u003cli\u003eSelect relevant spring rate for best results\u003c\/li\u003e\n\u003c\/ul\u003e\u003cbr\u003eSelect the most appropriate spring rate option to suit the fixed accessories on the vehicle:\n\u003cbr\u003e\n\u003cbr\u003eApproximate Lift Height: 30-40mm\n\u003cbr\u003e\n\u003cbr\u003e \tBPN-008 - 0-300kg Light Load\n\u003cbr\u003e \tBPN-008H - 300kg Constant Load\n\u003cbr\u003e \n\u003cbr\u003eSold Individually.\n\u003cbr\u003eWhere LH and RH are noted select one of each to create a pair.\u003cp\u003eHigh quality 4x4 suspension upgrades proudly sold by PPD Performance.\u003c\/p\u003e\u003ch5\u003eShipping Policy\u003c\/h5\u003e\n\u003cp\u003ePPD Performance offer custom built suspension solutions, with unique adjustability and performance.\u003c\/p\u003e\n\u003cp\u003eThese kits are assembled to order to suit your requirements, with an average lead time that can vary between 1-3 days.\u003c\/p\u003e\n\u003cp\u003eIf you need a specific eta, please contact us before ordering and we will be sure to assist you.\u003c\/p\u003e","brand":"Tough Dog","offers":[{"title":"Default Title","offer_id":46758943195310,"sku":"TD-BPN-008H","price":384.22,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2136\/3225\/files\/Tough-Dog-Leaf-Springs-1_2a53b23c-c5fb-4f95-b0d3-7cb5ffee50d7.jpg?v=1754614494","url":"https:\/\/ppdperformance.com.au\/products\/nissan-patrol-1980-1985-mq-mk-9-1980-1985-tough-dog-bpn-008h-tough-dog-rear-leaf-spring","provider":"PPD Performance","version":"1.0","type":"link"}
