Product Description

The Torque Solution TS-GR-634SB Solid Billet Driveshaft Flex Disc is engineered to replace the OEM rubber guibo in the 2020-24 Toyota GR Supra (A90/A91 platform). The factory rubber flex disc is prone to flex, distortion, and eventual failure under high load or high-power scenarios. This billet aluminum unit eliminates the flex/slop by providing a rigid connection, allowing better power delivery and drivetrain response.

Perfect for enthusiasts running boosted or high-power builds, track or drag setups, the TS-GR-634SB offers a direct bolt-in solution using supplied washers and hardware. While installation is straightforward, users should be aware that increased rigidity transfers more load to other driveline parts, so inspection of adjacent components is advised. Since fitment is confirmed through 2024 and 2025 generation coverage is unconfirmed, make sure to verify your vehicle's year and drivetrain architecture before ordering.
