Product Details

The Motive Gear FS8-8-31 is a full spool designed for Ford 8.8" rear differentials with 31-spline axles. A differential spool replaces the traditional spider gears and carrier assembly, locking both axles together to rotate at the same speed. This provides 100% power transfer to both wheels simultaneously, making it ideal for drag racing, rock crawling, and other high-performance applications where maximum traction is required.

Key Features:

  • Full spool design locks both axles for equal power distribution
  • 31-spline configuration for Ford 8.8" rear ends
  • Precision-machined from high-strength steel for maximum durability
  • Eliminates power loss through spider gears
  • Ideal for drag racing, off-road, and extreme performance applications
  • Manufactured using state-of-the-art production methods

Motive Gear differential components are engineered for racing and extreme-duty applications, providing the strength and reliability needed when standard limited-slip differentials aren't sufficient. Note that spools are designed for competition use and will cause both rear wheels to turn at the same speed, which affects handling on paved roads during turns.

Fast, parts in stock and you can pay with amazon.

quick and easy. Thank you

I did receive the parts I ordered in a timely manner. I was not given a confirmation number so I didn't know when to expect my delivery other then that my experience was good.

They had the best price on a hitch I was looking for and the shipping was fast also. The hitch was shipped bare except for taping the box of bolts to it thus leaving the hitch open and chipping the paint/powdercoating in quite a few places which I had to touch up before installing.

Easy to use website. The belts I ordered didn't have a picture but I knwew what I was looking for.
