We have produced a new tapered leaf spring that has softer spring rate and resist sagging.  Tapered or parabolic single leaf springs have around twice the articulation of the standard multi-leaf spring.  The tapered leaf spring spreads the stress in the leaf, and therefore resists sagging.

If you are interested in leaf springs, contact us.

The advantages are:

• Can handle greater articulation with softer spring rate
• Remarkably resistent to spring wind up, even with big horsepower V8's
• Provides the best possible lateral location for the axle (important for racing categories where panhard or watts linkage are not allowed.)
• Constant rate, as opposed to progressive rate of multi-leaf spring.  Constant rate is better for suspension tuning.  Constant rate will restrict body roll better on the outside wheel.
• Reduce weight compared to multi-leaf.
• Reduce friction in the suspension, caused by the rubbing action of the multi-leaf.
