1980–1981 Ford F100 3" Front / 4" Rear Complete Lowering Kit 

Lowering your classic Ford truck has never been easier or more reliable. The 1980–1981 Ford F100 3 Inch Front / 4 Inch Rear Complete Lowering Kit is engineered to give your truck the perfect stance while maintaining OEM alignment and dependable ride quality. Whether you’re building a custom street cruiser, weekend show truck, or simply want a more aggressive look, this kit has everything you need for a proper suspension drop — without sacrificing drivability.

Why Choose This Ford F100 Lowering Kit?

When it comes to lowering your 1980–1981 Ford F100, not all suspension solutions are created equal. Many owners are tempted to cut or heat factory coils, or use cheap aftermarket springs, but that almost always results in poor alignment, unsafe geometry, and rapid tire wear.

That’s why DJM Suspension designed this 3"/4" lowering kit specifically for the F100. Using precision-engineered lowered I-beams up front and a reliable hanger/shackle kit in the rear, your truck gets a balanced stance with predictable handling. OEM geometry is preserved, which means alignment specs stay within factory tolerances. No more fighting camber issues or scrubbing tires after a suspension drop.

Front Suspension: 3" Drop with Lowered I-Beams

The heart of this kit lies in the DJM lowered I-beams, designed to work with factory coils. Instead of relying on modified springs, these beams relocate the spindle mounting points, dropping the truck 3 inches in the front without disturbing ride quality.

• Works with Moog King-Pin Part Number 8551B (outside diameter of .8593" and length of 6.670")

• Factory coils are retained for ride comfort and durability

• Full alignment adjustment is maintained within OEM specs

• Heavy-duty construction prevents flex and distortion

• Engineered specifically for the 1980–1981 F100 platform

This approach ensures your front suspension performs like stock — only lower and sleeker.

Rear Suspension: 4" Drop with Hanger & Shackle Kit

To complement the front drop, the rear is lowered a full 4 inches with DJM’s hanger/shackle system. This proven setup repositions your leaf springs for a clean, factory-style drop without removing leaves or compromising load capacity.

• 4” drop in the rear for a level stance with the 3” front drop

• Maintains ride quality and strength

• Durable steel hangers and shackles built to last

• Bolts directly into factory locations with minimal modifications

This ensures your F100 not only looks great but also remains practical for real-world driving.

Shock Absorber Information

Proper shocks are crucial to any lowering job. This kit includes Front Shock Part Number 1415, designed to match the lowered geometry of your front suspension.

• Front Shock 1415 – Included

• Rear Shocks – Not included

  • Recommended: Rear Shock 1915 or Rear Shock 1900, depending on your factory mounting style.

By using the correct shock absorbers, you’ll avoid bottoming out and keep your truck comfortable even after the drop.
