Product Information

Features: These leaves are specifically made for the front spring on Ford Superduty trucks based on OE Spec design and SRI specifications. They are fully tapered just like the original springs and have correct arch to match so that they won't dig into the existing #2 leaf.

*Adding non-tapered leaves with your existing tapered leaves will generally result in the leaves breaking.

*Adding leaves with too much extra high arch (more than the existing leaves) to achieve lift also generally results in excessive leaf dig-in and generally results in breaking.

This is the actual add on leaf designed specifically for the stock springs on the SuperDuty suspension, and is perfect for heavy duty applications including front snow plows.
