GM 700R4 298mm Torque Converters
Performance Lockup Torque Converters for 700R4 Transmissions
The GM 700R4 gives performance vehicles a useful combination of a deep first gear and overdrive cruising capability, making it popular for hot rods, muscle cars, trucks and restomod builds.
Boss Hog 700R4 torque converters are available for stock-to-modified street and high-performance racing combinations.
When selecting a converter, consider more than advertised stall speed. Engine torque, camshaft, vehicle weight, rear gear, tire diameter and intended use all influence how the converter will behave.
The right combination can provide strong acceleration without sacrificing the street manners that make an overdrive transmission attractive in the first place.
