Heavy Duty Gear Sets


Gear Sets | Shorty Gears | 3-Speed Low Gear Sets | Reverse Ring Gears

Factory OEM Powerglides were originally manufactured using two distinctly different gear sets. The lower horsepower vehicles were equipped with a 1.82 low gear PG. Higher horsepower vehicles were equipped with a 1.76 low gear PG. The OEM 1.82 low gear set is made with a stamped steel planetary cage that is considerably lighter than the cast iron planetary cage used for the 1.76 low gear. All gear sets manufactured by ATI are based on the lightweight 1.82 type OEM planetary except for ATI High Impact Gear Sets. High impact gear sets are based on heavier 1.76 type OEM planetary. We usually recommend using these gears for vehicles making no more than 500 HP unless they are Stock, Super Stock or Competition Eliminator Class cars that require lightweight components.

Race car combinations that rely on reducing the rotating weight to meet performance standards are best served with the lightweight gear set which is an average of 8 lbs. lighter than the heavier unit. The lightweight gear set is extremely popular in many of the Stock, Super Stock and Comp Eliminator classes for that reason, and has proven to be very durable.
