Replacement of the 1-2-3-4 apply piston is an essential part of every 6L80/90 transmission rebuild. Stock cast aluminum apply pistons are a known weak point in these transmissions and can leave you stranded when they fail. Upgrade to our billet apply piston for reliability and peace of mind on your next build.
