DJM Suspension 3" Lowering I-Beams (1973-1979 Ford F100) - DB3004A-3
3" Lowering King Pin I-Beams for 1973-1979 Ford F100
The DJM Suspension 3" Lowering I-Beams - Part Number DB3004A-3 - are engineered to provide a true 3" front drop for 1973-1979 Ford F100 trucks equipped with king pin suspension. These beams replace the factory units and lower your truck properly while maintaining correct alignment geometry and suspension travel.
These king pin I-beams drop the front of your F100 3" and fit all F100 models from 1965 to 1979, regardless of drum or disc brake configuration. If your truck currently has drum brakes and you want to upgrade to discs, simply use the disc brake spindle and king pins with these beams.
Each set includes tie rod extenders to keep the tie rods properly centered in the radius arms just like stock height. A custom wrench is also included to simplify installation.
Caution: Attempting to lower I-beam trucks by cutting or heating springs, or even using certain lowering springs, can cause alignment issues that cannot be corrected. Properly engineered drop beams eliminate those problems.

Yes. If converting from drum to disc brakes, use the appropriate disc brake spindle and king pins with these beams.
