Drive Shaft Shop GMC5M-1-E Aluminum Torque Tube Driveshaft Coupler Eliminator 1000HP+ C5 Corvette

The Drive Shaft Shop GMC5M-1-E is a heavy-duty 3.5" aluminum torque tube driveshaft designed as a direct replacement and coupler eliminator for the C5 Corvette with a 6-speed manual transmission. Built for high-horsepower applications, this driveshaft replaces the factory torque tube and eliminates the OEM rubber guibo couplers that are prone to failure under aggressive driving and elevated power levels.

Constructed from 3.5" x .125" wall 6061-T6 aluminum with custom CNC-machined ends, this shaft is engineered to handle the rigors of performance driving without the flex, distortion, or breakage common to the factory unit. The stock driveshaft is manufactured from a smaller-diameter tube that bends under hard acceleration, accelerating rubber coupler wear and eventually leading to drivetrain failure.

Key Features:

• Heavy-duty 3.5" diameter, .125" wall 6061-T6 aluminum construction
