The “Squarebody” Chevy truck is growing in popularity, so American Powertrain introduces its new Pro-Fit 5-speed and 6-speed system.

This new Pro-Fit system features the rock solid TREMEC TKO 5-speed or the MAGNUM 6-speed transmission with all the installation parts you need for a complete installation. The Pro-Fit system includes American Powertrain’s Revolutionary shifter mechanism with an OE 4-speed shift position, the company’s adjustable X-Factor cross member and 3.5-inch DOM driveshaft, speedometer hookup, reverse light wiring, and your choice of shifter knobs. Several different shifter handles are available for bucket and bench seat applications.

The transmissions are compatible with the original bell housing, flywheel, clutch linkage, and most OE spec clutches.  A hydraulic clutch upgrade is available. Five-speed Pro-Fit Kit prices start at $3,995 including the transmission and are ready to ship now. All Pro-Fit kits are covered by American Powertrain’s 2-year warranty and come with free comprehensive tech support.
