Powerglide

1.80 Ratio Contender Gear Set
Part No. 180S-1K

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 gear sets which offer a significant upgrade from OE helical gears. Rated up to 1,000 horsepower, this gear set contains Sonnax Premium 9310 sun gears and 8620 pinion gears. The billet drum flange is 12-tooth (OE) design. 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.
