Sonnax piston plate AL-DA-3P, along with required countersunk rivets, replaces plates in Allison® 1000/2000/2400, 2005-earlier converters. The piston plate has an improved design with increased wall thickness in critical areas, making for a stronger and more durable piston.
To make this assembly you will need an Allison 1000/2000/2400, early-style piston damper assembly, Sonnax piston plate AL-DA-3P and 18 rivets.
