Compared to conventional leaf springs, parabolic springs 257840 Leaf Spring are able to resist 

more compression and have better flexibility. The flexibility results to better ride quality. The vertical speed 

movements are also easier to adjust with these types of springs. Due to the structure and components involved, 

parabolic springs are also lighter. This is an important factor when the priority is for maximum performance.

Another great application for parabolic springs Volvo Trailer 257840 Leaf Spring is for off-road vehicles 

in which the flexibility of the spring is more effective in keeping the wheels always in contact with the ground 

compared to stiffer conventional springs.
