Introducing a brand new racing transmission platform to the Loganbuilt line up! 2 Speed Turbo 400! There is no doubt that small tire "No Prep" racing is amongst the hottest forms of racing right now. I wanted to take my knowledge of building reliable transmissions for high torque, heavy, diesel racing vehicles and bring that information into the small tire world to offer a great product for drag racers. I spent the 2023 season working with the guys at Tin Soldier Racecars, R&Ding this platform in Brad Arnold's True Street Buick. After an entire season of racing with 1500+HP at 3200+lbs, and multiple 4 second 1/8 mile time slips, this 2 speed 400 has proven to be reliable and repeatable. Since working with the boys at Tin Soldier Racecars, I have dubbed this transmission as the, Small Tire Soldier and finished it out in a battle ready desert strom base coat, clear coat paint scheme. These soldiers are suited up with a host of parts, ready to go to war in your no prep car!
