The TSI-2584 is an aftermarket Powerglide reverse piston machined from 6061 billet aluminum. The piston measures 0.875” tall and is a good starting point for a six-disk reverse clutch pack setup. It can be used with a clutch pack with less clutch disks but additional steels will be required to obtain the correct clutch pack clearance.
