Terrain Tamer Long awaited parabolic spring kit, will ship approx. 1 week from your order due to popular demand, be quick.
These springs are suited for a 50mm lift, and 0–500KG weight capacity, this is the only option currently available for 60 Series Landcruisers.
Traditional 4WD leaf springs are often thick, heavy, uncomfortable and loud, offering little to no flex. In response to this Terrain Tamer developed their 4WD Parabolic Leaf Springs, applying a carefully researched design and modern technology to a well-established idea from the trucking industry.
Utilising new technology on an old design, the parabolic springs allow for a comfortable ride whether the vehicle is fully loaded or empty.
DON’T MISS OUT.
What is a parabolic spring?
Parabolic Leaf Springs typically contain fewer leafs than traditional leaf packs and get their name from their tapered “parabolic” design, meaning they are thicker in the centre and thinner at the ends. Already a well-established idea in the trucking industry, Terrain Tamer have applied their own carefully researched design and modern technology, and use a special grade steel to develop their range of Parabolic Leaf Springs specifically for 4WD vehicles.
How do parabolic springs work?
Traditionally heavy linear leaf packs can also be uncomfortable and loud and can create a safety issue, as they offer little to no flex, meaning that when a driver hits a bump, or finds themselves in a rough offroad situation, the rigidity of the leaf pack will cause the opposite wheel will lift, spinning and losing traction, ceasing drive and effectively endangering the driver. In a Parabolic spring, the tapered design of each leaf allows the stress to be distributed more evenly across the spring, and each leaf is allowed to work independently with enhanced flex without sacrificing load capacity, and keeping all four wheels on the ground.
What are the advantages of parabolic springs?
This design of Parabolic Springs eliminates the weight of often heavy, thick, traditional leaf packs and dramatically reducing the unsprung weight of the vehicle, essentially freeing up the weight needed for practical use. This lower unsprung weight addresses the issue of GVM limits, and also acts to create a more comfortable ride when the vehicle is unloaded, accommodating the varying and ever-changing applications that the modern day 4WD is used for, freeing up weight for towing heavy loads, carrying tools or touring with the family, and ensuring it is comfortable whether empty or loaded. The Parabolic shape also provides better axle articulation, as well as almost no interleaf friction, allowing the spring to compress or extend with ease without touching each other until there is a reasonable load on the vehicle. This feature means that the springs are not only quieter, but it also acts to help minimise any issues with rust build up, which can be a major cause of failure in standard leaf springs.
Do parabolic springs offer better flex?
The Parabolic design allows the spring to flex while still providing the strength needed to bear the weight of heavy loads. This is particularly useful in 4WD applications that carry excessive load on the driveline, or when challenged with difficult terrain, as the flex afforded with a Parabolic Spring lets it give a little when the driver hits a bump in the road, allowing the differential housing to rotate with the springs and effectively providing a smoother ride, reducing the shock transferred to the crown wheel and pinion, stopping the wheel from spinning and maintaining safety and drive. The same force with a standard leaf pack would almost certainly cause more shock to the vehicle and driver
