Sonnax High Clutch Pistons
If there's a Powerglide transmission under your hood, chances are you're either a drag racer or restoring a GM car that's been around for a half-century. Sonnax high clutch pistons are direct OEM replacements optimized for those vintage 2-speed applications. Built from 6061 forged aluminum, these pistons won't crack under pressure as some cast versions do. You can also machine these Sonnax pistons to allow for various quantities and thicknesses of clutch steels and frictions. For drivetrain components, trust the award-winning industry leader--an American company that's 100 percent employee-owned. Developing quality solutions for their customers is a daily mission.
