TCI Auto 241602 Maximizer Street Performance Torque Converter TH400/425/375 Wide-Bolt Pattern

The TCI Auto 241602 Maximizer Street Performance Torque Converter is purpose-built for modified 4x4 trucks running GM TH400, TH425, or TH375 transmissions with a wide-bolt pattern. Sharing performance DNA with TCI's proven Saturday Night Special series, the Maximizer is engineered with significant upgrades to handle the unique demands of off-road and dual-purpose truck applications.

Key Features:

• Heavy-duty construction — extra reinforcement and thicker mounting surfaces resist the additional load and vibration common in modified 4x4 drivetrains
• Tougher turbine splines — designed to withstand the high-stress demands of off-road use and performance modifications
• Anti-ballooning plate — helps maintain converter integrity under high-RPM and high-load conditions
• 1,600–2,000 RPM stall speed range — delivers improved initial takeoff and prevents engine lugging when running oversized tires
• Power-matched calibration — tuned specifically for trucks that serve double duty as daily drivers and off-road rigs
• Wide-bolt pattern compatibility — fits 1965–1991 GM TH400, TH425, and TH375 transmissions (except variable pitch)

By raising the stall speed into the 1,600–2,000 RPM range, the 241602 puts power down more effectively off the line, resulting in improved rear-wheel horsepower and quicker elapsed times. Whether you're navigating the trails or the daily commute, this converter is engineered to keep up.
