START_LONG The Early Bronco 1.5″ Standard Duty Leaf Spring Bundle, designed by James Duff Inc., is ideal for maintaining and improving the performance of your 1966-77 Early Bronco. The innovative engineering of this leaf spring reduces pinion angle, essentially minimizing the need for pinion corrections that could compromise vehicle handling. This feature not only enhances drivability but also contributes to superior performance, making it a highly reliable option for any Bronco enthusiast.

Designed with a progressive rate and a robust 11-leaf construction, this leaf spring accommodates most Early Broncos without requiring additional adjustments. Its premium features include Teflon wear pads, tapered ends, a double wrap for safety on the mainspring, and catch stops to prevent over-articulation, ensuring durability and extended service life.

For those looking to customize their ride, an XL add-on spring will soon be available, making it an excellent choice for towing and heavier loads. To further enhance your suspension system, matching coil springs and a variety of upgrade options, such as leaf spring and shackle mounting hardware, U-bolts, and heavy-duty shackles, are available separately. Additionally, our 1/2″ lift block can facilitate optimal axle positioning for tire-to-fender clearance, especially beneficial for uncut lifted 66-77 Broncos.
