Extreme gear sets 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.
Each gear set includes a flanged sun gear and a ring gear. The flange is machined from billet, not a stamped piece. The flange is broached and matched to the sun gear for a precise press fit that does not require welding.
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
