Ford F100 rear axle Dana 44 leaf springs including axle flip kit

inventory at Buy Mustang parts Ltd, a complete Ford F-100 rear-end setup featuring a Dana 44 axle and leaf springs with a pre-installed or included flip kit is a prime offering for the “Pro-Touring” and classic restoration markets.

While most F-100s transitioned to the Ford 9-inch by the late 1950s, the Dana 44 was the standard rear axle for the early 1953–1956 models. This setup is highly sought after by purists and those performing “Crown Vic” front-end swaps who want a matching lowered stance in the rear.

1. Technical Specs: Dana 44 & Leaf Springs

To provide your usual professional-grade detail, ensure you verify these dimensions for your listing:

• Axle Tube Diameter: Most Dana 44 tubes for this era are 3 inches or 2.75 inches. Flip kits are diameter-specific; using a 3-inch kit on a 2.75-inch tube will lead to “axle twist” under torque.

• Spring Width: Early F-100 leaf springs are typically 2 inches or 2.25 inches wide.

• Spring Count: Standard luxury/comfort packs often have 5 to 7 leaves. A “Top Condition” pack should have no visible cracks and original anti-friction pads between the leaves.

2. The “Axle Flip” Mechanics

The flip kit relocates the leaf springs from the top of the axle to the bottom.

• Drop Height: This modification typically provides a 4 to 6-inch drop, instantly giving the truck a “slammed” or leveled luxury profile.

• Pinion Angle: High-quality flip kits (like those from CPP or DJM) include offset indexing holes to correct the pinion angle. This ensures the driveshaft doesn’t vibrate at highway speeds—a key selling point for your premium buyers.
