As the spring compresses, the secondary stage engages to mitigate excessive sag, providing a balanced ride even when fully loaded.\u003c\/p\u003e\n\u003cp\u003eThe manufacturing process of these leaf springs emphasizes durability, featuring advanced corrosion protection and sag prevention techniques. Tough Dog offers 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\u003eEach spring is precision mandrel and die-formed, oil quenched, hardened, and tempered to guarantee longevity. A military wrap is standard across all part numbers, ensuring added strength and reliability. The springs are accurately heat-treated and constructed from high-grade spring steel, with anti-friction pads included in most applications to enhance performance.\u003c\/p\u003e\n\u003cp\u003ePre-stressed to maintain optimal ride height, these leaf springs undergo rigorous load rate testing to ensure they meet the demands of various applications. If your vehicle is equipped with additional accessories, Tough Dog provides different spring rates to accommodate constant load scenarios.\u003c\/p\u003e\n\u003cp\u003eApproximate raised height ranges from 40-50mm, with specific models designed for varying load capacities: BPN-010 for 0-300kg light load, BPN-010H for 300kg constant load, FS39M-LH and FS39M-RH for 500kg constant load on passenger and driver sides respectively, and FS38M-LH and FS38M-RH for constant GVM on both sides.\u003c\/p\u003e\n\u003cp\u003eWhen selecting your leaf springs, it is advisable to pair left-hand (LH) and right-hand (RH) springs to create a complete set. Additionally, it is recommended to fit long travel shock absorbers when installing raised springs to optimize performance.\u003c\/p\u003e\n\u003cp\u003eConstant load refers to weight that is permanently added to the vehicle, such as canopies, steel trays, draw systems, fridges, toolboxes, rear bars, or spare wheel carriers. Selecting the appropriate spring rate is crucial for achieving optimal load carrying capacity, ride quality, and ride height.\u003c\/p\u003e\n\u003cp\u003ePlease note that images provided are for representation purposes only and may not accurately depict the specific part number you are viewing.\u003c\/p\u003e\u003ch4\u003eLeaf Spring Features\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\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-010 - 0-300kg Light Load\u003c\/li\u003e\n\u003cli\u003eBPN-010H - 300kg Constant Load\u003c\/li\u003e\n\u003cli\u003eFS39M-LH - 500kg Constant Load Passenger Side\u003c\/li\u003e\n\u003cli\u003eFS39M-RH - 500kg Constant Load Driver Side\u003c\/li\u003e\n\u003cli\u003eFS38M-LH - Constant GVM Passenger Side\u003c\/li\u003e\n\u003cli\u003eFS38M-RH - Constant GVM Driver Side\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eImportant Notes\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eLH and RH noted select one of each to create a pair\u003c\/li\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 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: 40-50mm\n\u003cbr\u003e\n\u003cbr\u003e \tBPN-010 - 0-300kg Light Load\n\u003cbr\u003e \tBPN-010H - 300kg Constant Load\n\u003cbr\u003e \tFS39M-LH - 500kg Constant Load Passenger Side\n\u003cbr\u003e \tFS39M-RH - 500kg Constant Load Driver Side\n\u003cbr\u003e \tFS38M-LH - Constant GVM Passenger Side\n\u003cbr\u003e \tFS38M-RH - Constant GVM Driver Side\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":46758943326382,"sku":"TD-BPN-010","price":436.5,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2136\/3225\/files\/Tough-Dog-Leaf-Springs-1_55aa55ae-b0c6-4b64-8ae0-6949027b9829.jpg?v=1754614498","url":"https:\/\/ppdperformance.com.au\/products\/nissan-patrol-1997-2015-gu-cab-chassis-coil-leaf-12-1997-2015-tough-dog-bpn-010-tough-dog-rear-leaf-spring","provider":"PPD Performance","version":"1.0","type":"link"}
