What does a mini spool do in a differential?

What does a mini spool do in a differential?

Mini spools are designed to be installed in an existing open differential and are used to replace the side gears and spider gears. They also lock both axles in place so that they both put power to the ground with equal torque and traction. Many weekend racers use mini spools as a lower-cost alternative to a full spool.

Can you use a mini spool on the street?

The mini spool replaces those and locks the two azles together. You can also weld the gears together but thats even more dangerious. I’ve had a mini spool before and it’s hard on the azles in tight turns, their mainly made for going straight but you can drive them on the street (if )your careful.

What is a spool differential?

Spool. A spool is essentially a differential delete that permanently locks the left and right axle shafts together. Full power is transmitted to both the left and right tires at all times. It involves welding the spider gears inside the differential, converting it to a full spool.

What is a spool rearend?

A spool is basically a steel collar that splines both axleshafts together with a flange to bolt the ring gear onto. Very simple to be sure, but this differential replacement is too hard-core for 99 percent of street-driven 4x4s.

What’s a spool?

Definition of spool (Entry 1 of 2) 1 : a cylindrical device which has a rim or ridge at each end and an axial hole for a pin or spindle and on which material (such as thread, wire, or tape) is wound. 2 : material or the amount of material wound on a spool. spool.

What is an automotive spool?

A full spool is basically just a piece of metal the ring gear is bolted to that the output shafts slide into. A mini spool is a set of parts that replace the sun gears in the diff unit, to again give a solid driven assembly.

What is a spool rear end?

What are the different types of differential?

There are four common differentials used between vehicles – open, locking, limited-slip and torque-vectoring.

What is spool gear?

A spool replaces the differential carrier, locking the axle shafts together. Locking the axles provides maximum traction for off road use. For use only in rear axle, use in the front will limit turning ability.

What is a spool in rear end?

A spool is one solid part that replaces all components of a differential. The 10 Bolt spool fits the GM 10 Bolt Rear End. A drag racing spool will always turn both axles at the same speed with an equal amount of force. Due to the simplistic design, it is much stronger and lighter than any differential.

What are spool gears?

Spools. A spool is carrier setup that turns both wheels on an axle the same speed as the ring gear. Spools are lousy on pavement because there is no differential action, and they eat tires (especially if you ever turn corners . But you can always count on power to both wheels. Spools are common in drag racing.

What is a MiniMini differential spool?

Mini spools fit inside an existing open differential, replacing the side and spider gears. They’re usually less expensive, but aren’t as strong as full spools. For maximum…

What are the different types of spools used for differentials?

Motive Gear manufactures both full spools and mini spools for GM 7.5-, 8.2- and 8.5-inch 10-bolt applications and passenger car 12-bolt, as well as a unit for Dana 44s. Full steel spools are listed for Dana, Chrysler, Ford and GM passenger differentials, with additional listings for Ford 9-inch racers wanting a lighter-weight spool.

What is the difference between a full and a mini spool?

There are no moving parts, they add support to the ring gear, and they can save unsprung weight. Mini spools fit inside an existing open differential, replacing the side and spider gears. They’re usually less expensive, but aren’t as strong as full spools.

What is a mini spool for Ford 9-inch third members?

Motive Gear’s mini spool for Ford 9-inch third members is heat-treated and CNC-machined steel for strength and durability. Because they have no moving parts, spools can handle more torque than a conventional differential, and are much lighter.
