HPP-19250 – Aftermarket HD Powerglide Reverse Piston Return Spring Kit

The HPP-19250 is an aftermarket HD Powerglide reverse piston return spring kit that we have prepared that is made up for a set of HPP-19150 HD return springs, a Sonnax 28709 spring retainer and an HPP-19151 aftermarket spring retainer clip. These are the recommended reverse assembly parts to change when building a race Powerglide with a trans brake.

This is the combination of parts that we use in our in-house builds, this combination has a proven track record of providing a fast, consistent, and reliable reverse piston release for trans-brake applications.
