This is our new Super-Flex leaf springs specifically designed with extreme travel and superior ride quality in mind.
A progressive primary soft suspension carrying the vehicle weight at ride height, dampened and controlled by high quality shock absorbers maximizes complete suspension travel for a high performance ride.
Bronco Progressive Series springs are all 11-leaf units complete with full military-wrapped spring eyes.
A higher leaf count spring allows the use of thinner leaf material.
Using more leafs yields a more flexible progressive leaf stack, or pyramid, which produces a much smoother spring rate curve throughout the complete suspension cycle.
The even, linear compression rate curve of Progressive System spring is the primary is the primary key to excellent ride quality.
This is not a "one spring rate for all" mentality; Providing different designs for the vehicle weight and application.
Super-flex springs include anti-friction pads inserted between each leaf for a smoother ride and quiet operation, full military-wrapped spring eyes for superior durability, Rebound clips, and functional Urethane compression travel stops.
