Parabolic Leaf Springs

Go-4LO Parabolic Leaf Springs:

Compared to conventional leaf springs, Go-4LO parabolic springs can resist more compression and have better flexibility. The flexibility results in better ride quality. Due to the structure and components involved, parabolic springs are also lighter. 
Each leaf in parabolic springs is tapered to be thicker at the center and slowly thins out towards the ends. This is different from the conventional leaf springs wherein the leaves are in contact with each other and in which each leaf has a uniform thickness from end to end. This is a crucial factor when the priority is for maximum performance.
An especially key factor in Off-road vehicles is that the flexibility of the spring is more effective in keeping the wheels in contact with the ground compared to stiffer conventional springs.
