Billet 6R80 Intermediate Shaft – 300M Alloy Steel (Heavy Duty Upgrade)

Upgrade the weak link in your 6R80 with our Billet 6R80 Transmission Intermediate Shaft, precision-machined from premium 300M alloy steel for extreme strength, durability, and high-torque reliability. Designed for serious street builds, drag racing, boosted applications, and heavy-duty performance use, this intermediate shaft is built to handle the power levels that push factory components past their limit.

The stock 6R80 intermediate shaft can become a failure point under high horsepower, aggressive shifting, and hard launches — especially in supercharged, turbocharged, nitrous, or high-grip setups. Our billet upgrade is engineered for drivers who demand confidence when the transmission is loaded hard, shift after shift.
