Maximum Performance w/ Brake - Reversed Pattern, 6" Extension

The COA‑31125 represents Coan Racing’s elite, race‑honed Turbo Hydramatic 350 transmission, crafted for drivers who demand uncompromising performance from launch to finish. Equipped with a brake and a reversed shift pattern, this unit ensures razor‑sharp, immediate engagement off the line, providing a competitive edge in drag racing environments. At its heart is the Extreme Duty sprag race and a 36‑element sprag, together offering rock‑solid one‑way clutch support capable of withstanding brutal torque and aggressive launches without faltering.

Durability meets precision with the inclusion of a billet aluminum direct drum, mated to a robust five‑clutch setup. The 300M alloy input shaft brings aerospace-grade strength to the assembly, enhancing overall drivetrain resilience under high-stress conditions. A lightened sun shell and deep fabricated aluminum pan further optimize performance by reducing rotating mass and improving fluid management. This model also features a roller-bearing package and a billet roller-bearing extension housing, which deliver superior structural rigidity, precise tailshaft alignment, and enhanced drivetrain smoothness under load.

Engineered and assembled in the USA to rigorous Coan Racing standards, the COA‑31125 is the pinnacle of drag‑strip transmission builds. It’s tailored for racers seeking maximum reliability, rapid power transfer, and unwavering consistency, all wrapped up in a race‑ready package that doesn’t back down when the lights go green.
