Parabolic vs. Conventional Leaf Springs: Understanding the Key Differences

Leaf springs have been an essential component of vehicle suspension systems for centuries, particularly in commercial and heavy-duty vehicles. Over time, advancements in suspension technology have led to the development of parabolic leaf springs, an alternative to conventional multi-leaf springs. While both serve the same fundamental purpose—supporting the vehicle’s weight, absorbing shocks, and maintaining stability—there are key differences between the two in terms of design, performance, durability, and overall efficiency. This article explores these differences to help vehicle owners, manufacturers, and fleet operators make informed decisions.
