Sonnax anti-wear washer kits prevent metal-to-metal contact. Direct contact between your aluminum Powerglide ring gear and the reverse clutch pack pressure plate causes damage to both components and generates metal debris that circulates throughout the transmission. With the OE design, this is tolerable at original speeds, but is a far greater concern in racing transmissions at higher operational speeds. Sonnax kits include a shim and anti-wear washer that will work with any ring gear that accepts stock-type reverse clutch plates.

Sonnax retaining rings are stamped from high-strength, roll-tempered steel, providing additional muscle to resist deflection better than mild steel OE retainers. Successful ET racing requires consistent transbrake release; that usually means utilizing stiffer springs—which leads to the need for stronger spring retainers that won't be deflected. Sonnax no-flex reverse spring retainers are small solutions to faster transbrake response times.

Upgrade your transmission's clutch pack with Sonnax automatic transmission clutch steels. These premium-quality steel parts give you the best combination of coefficient of friction and performance. Sonnax offers severe-duty clutch steels for use in a variety of automatic transmissions—including racing applications. These steels are available with up to double the number of external teeth as OE. With more teeth engaged, wear should be reduced dramatically. Anti-drag tabs create the maximum clearance between the friction and steel when the clutch is disengaged. Turbulator holes reduce parasitic drag. Combining anti-drag tabs and turbulator holes significantly reduces the heat generated when the clutch freewheels.
