Draw tapered and diamond cut leaves - Ensure the load is progressively distributed over a larger surface area, reducing the high stresses that develop at leaf ends, provides increased ride quality
Fully scragged and load tested - Scragging ensures the spring takes a permanent 'set' which reduces the risk of sagging, load testing ensures the spring meets the required specification
Two-stage leaf pack - Featured on most rear springs for optimum comfort, unladen the vehicle is largely riding on the primary stage, with the secondary stage providing additional support
Military wrap - Designed to provide added safety. Shot peening - The tension side of all leaves is shot peened to reduce spring stress, process can double the life of a spring
Anti friction pads - Regreasable nylon interleaf liners reduce friction at the leaf tips where the load is the greatest
Flat axle seat area - Allows a positive, safe axle mount reducing spring stress and increasing spring life
Bolt clamps and liners - The leaf clamps are bolted to allow installation of anti squeak nylon liners
