Parabolic leaf springs provide smoother riding comfort and less stiffness than which type of springs?

• A. Mono-leaf springs
• B. Multi-leaf springs
• C. Coil springs
• D. Torsion springs

Answer: (B)

Parabolic leaf springs achieve a smoother ride by using leaves that taper toward the ends, which reduces the number of leaves carrying load and lowers the spring rate. This design cuts down internal friction between leaves and spreads the load more progressively, so the suspension responds more softly to bumps. Traditional multi-leaf springs have multiple rigid leaves pressed together, which makes the pack stiffer and can transfer more road harshness into the chassis. The parabolic arrangement lightens the stack and softens the overall stiffness, delivering greater riding comfort. Coil springs and torsion springs operate on different principles and aren’t leaf-spring configurations, so the direct comparison centers on how parabolic leaf springs differ from the conventional multi-leaf packs.
