Load testing ensures the spring meets the required specification.
This provides increased ride quality and protection against leaf breakage, significantly increasing the spring life. Draw Tapered & Diamond Cut Leaves: Ensure the load is progressively distributed over a larger surface area, reducing the high stresses that develop at leaf ends. When unladen the vehicle is largely riding on the primary stage, with the secondary stage providing additional support when a heavy load is added.
