Solid Axle Swap Kit (4x4) - 1980-1996 Ford F150/Bronco

DIY Leaf Spring Solid Axle Conversion Kit – 1980–1996 Ford F-150 & Bronco

Convert your 1980–1996 Ford F-150 or Bronco from the factory coil-sprung Twin Traction Beam (TTB) front suspension to a traditional leaf spring solid axle setup with our DIY Solid Axle Conversion Kit.

Designed for builders who want the strength, simplicity, and capability of a solid front axle, this weld-on kit provides the foundation needed to install several popular Ford Dana 50 and Dana 60 axle combinations. Choose between 2-inch or 4-inch drop configurations, measured in relation to the factory F-350 ride height, allowing you to tailor the setup to your build.

Whether you're building a capable trail truck, upgrading an OBS Bronco, or simply looking to eliminate the factory TTB suspension, this kit gives you a solid starting point without locking you into one specific axle or spring combination.

Estimated Lift

When using factory-style gas-engine OBS or Super Duty leaf springs, expect approximately 4–6 inches of lift over the stock F-150/Bronco ride height.

Final ride height will vary depending on spring selection, axle configuration, vehicle weight, and other suspension components.

Additional Axle Options

A Ford F-250 Dana 44 may also be used with additional fabrication. The spring pads will need to be repositioned, and the axle can be converted to a 5-lug configuration for builders wanting to retain the factory F-150/Bronco rear axle and matching wheel bolt pattern.

Important Installation Information

This is a DIY weld-on conversion kit and is NOT a bolt-on installation.

Installation requires welding, fabrication, suspension setup, and proper axle positioning. Additional components may be required depending on your specific axle, steering, brake, driveshaft, and suspension configuration.

Professional installation is recommended if you do not have experience with suspension fabrication and welding.

Built for the guys who want to ditch the TTB and build their F-150 or Bronco the way they want it.
