If you're rebuilding a classic Muncie 4-speed transmission, you're gonna want these.

It's a set of upgraded synchro sleeves from Platinum Drivetrain.
You get the 1-2 and the 3-4 sleeves.

They're the torque lock style, which is stronger than the stock ones.

They fit the Muncie M20, M21, and M22 transmissions.

The manufacturer part number is T10-15.

They're brand new and come with a 1-year warranty.

These are a common upgrade during a rebuild to improve shifting and durability, especially if you're putting down some power.

A solid piece for your hot rod or muscle car project.
