Sonnax offers complete Powerglide planetary assemblies in a variety of ratios and configurations to ensure you get the performance you want without overpaying or sacrificing quality.
The value-priced Contender series features high-quality Powerglide planetary assemblies which offer a significant upgrade from OE helical gears. Rated up to 1,000 horsepower, Contender series come assembled with Sonnax Premium 9310 sun gears, 8620 pinion gears, OE-style thrust washers and OE length, 4340 cut-spline output shafts or short length, HY-Tuf shafts. The billet drum flange is a 12-tooth (OE) design. The gears in Contender series gear sets are covered by a one-year warranty.
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
