TH400 Competition Trans. W/4in Tail Shaft

The COAN TH400 Competition Transmission with 4-inch Tail Shaft is designed for serious drag racing, street performance, and high-horsepower applications where reliability and power transfer are critical. This transmission is ideal for builders and racers who require maximum durability in competitive environments, whether launching a nitrous-fed big-block or managing extreme torque loads from a supercharged engine.

Engineered with reinforced internals and upgraded clutch materials, this competition-grade TH400 transmission is built to withstand the severe duty cycles of track and strip racing. The 4-inch tail shaft extension allows for flexibility in mounting location and driveline angle geometry, which are essential for designing custom chassis or converting classic muscle cars to modern performance standards.

This transmission is perfect for dedicated race cars and street-legal performance builds, ensuring that a stock TH400 unit can be replaced where it cannot safely manage engine output. Proper driveline support and torque converter selection are necessary for installation, making it a suitable choice for those looking to enhance their vehicle's performance.
