Know what’s hotter than the 1973-1987 GM truck segment right now? Not a damned thing. That’s what. The crew at American Power train knows this and that’s why they have released new Pro-Fit 5-speed and 6-speed System for 1973-87 Chevy square body trucks. This is their proven, engineered, and awesome system for upgrading your transmission to something modern, fun, and strong. No more slip sliding around with your TH350 or TH400. Nope, you can stick a stick in there and really have a blast!

The kits are designed to land the shifter in the factory location where the typical four speed shifter would have come to use when trucks were so optioned. The X-Factor crossmember means that the transmission will be securely fastened to the truck, and the new driveshaft, speedo hookup, reverse light wiring, and other detail parts will have you on the road in no time. This is awesome!

Yes, the crew from American Powertrain is on the Hot Rod Power Tour but they are still releasing new products. Awesome!
