What is the best Ford rear end?
The 9-inch Ford Rearend is the Strongest Rearend Out There—It’s All Due to “Hypoid Distance” 1] The 9-inch Ford has no differential case gear-ratio range restrictions; one differential accepts all gear ratios from the 2s through the 6s.
How hard is it to rebuild a rear differential?
A complete rear differential replacement includes replacing the housing, gears, bearings, and seals. The average time it takes a certified mechanic to perform a differential rebuild at a shop is usually three to five hours.

Under regular use and proper maintenance, differentials should last 150,000 miles or the life of a vehicle.
Why is a Ford 9-inch so good?
The 9-inch’s design benefits performance from a ‘bigger is better’ standpoint as well. Ford 9-inch diffs feature larger diameter ring gears which creates additional distance between the centerline of the ring gear and the centerline of the pinion gear, known as hypoid distance. This relationship impacts performance.
What is special about a Ford 9-inch rear end?
The removable center section of the 9-inch rear end allows the ring and pinion gears to be set up on a bench, rather than in the housing, and rear end ratios can be changed quickly. Racers can also carry extra center sections with different ratios for experimentation purposes.

The Achilles’ heel of the stock 8.8 Ford rearend is its 28-spline axles, especially when compared to the Chevy 12-bolt’s stronger 30 splines.
Can rear differential cause transmission problems?
When the differential doesn’t perform well, it creates metal-on-metal friction that wears down surfaces. The resulting heat weakens gears and can cause component failure and transmission problems. A bad differential makes the car harder to control turning corners, and that can be dangerous.
What does a bad diff sound like?

What gear ratio is better for torque?
The numerically higher gear ratio (in this case, 4.30) increases wheel torque and improves acceleration from low speeds. But the engine does have to run faster to achieve a given speed.
