Non-Application Specific
The TCI® fuel-efficient Maximizer™ Towing Converter is designed to reduce the slippage found in all non lock-up torque converters. This series of torque converters enables transmissions to run cooler and reduces engine rpm at highway speeds. In addition to the resulting fuel mileage increases, the Maximizer™ Towing Converter also lowers transmission temperature by as much as 20° F. This is an excellent choice for motor homes, tow vehicles and other heavy load applications. Stall speeds range from 1,000 to 1,200 RPM.

Maximizer Street

  • Built with extra reinforcement, tougher turbine splines and thicker mounting surfaces to withstand additional load and vibrations put through drivetrain by a modified off-road 4x4 truck
  • Additional stall allows trucks to see better initial takeoff and will not lug engine when using big tires
  • Improved rear wheel horsepower and elapsed times are result of efforts to match converter to power range of most trucks that do double duty as off-road and daily drivers
  • Stall speeds range from 1600 to 2000 RPM


                        
                        
Description
Non-Application Specific
These torque converters have some of the same performance characteristics as our standard Saturday Night Special® series for street applications, but they are built with extra reinforcement, tougher turbine splines and thicker mounting surfaces to withstand the additional load and vibrations put through the drivetrain by a modified off-road 4x4 truck. By providing additional stall, trucks will see better initial takeoff and will not lug the engine when using big tires. Special attention is made to match the converter to the power range of most trucks that do double duty as an off-road and daily driver. Improved rear wheel horsepower and elapsed times are a result. Stall speeds range from 1600 to 2000 RPM.
