Sonnax offers complete Powerglide planetary assemblies available with a variety of gear set options. These assemblies come in various configurations to meet different build requirements. HY-Tuf, rolled spline output shafts are available in the OE length or short length, along with an optional 300M rolled spline short shaft version. The machined-from-billet drum flange is offered either 12-tooth (OE) or 24-tooth configurations. Extreme planetary assemblies from Sonnax include Advanced Process sun gears and pinions made to the same exacting standards used on Formula 1, Nascar and other high-end professional racing circuits. Advanced Process parts undergo an additional three-step process that allows for greater durability and higher levels of performance. These units are fully assembled and ready to install.
I run a Sonnax 1.80 straight cut gear set and have had no problems or issues, plan on purchasing another real soon for another car we are putting together. Thanks Sonnax for the reliability and durability in your product.R. Merrill
