DSS Mazda 1986-1992 (FC) Turbo II 1-Piece Aluminum Driveshaft MZSH4

If you're pushing your 1986-1991 Mazda RX-7 Turbo II hard, you know the stock two-piece driveshaft can be a weak point. This 1-piece aluminum driveshaft from Driveshaft Shop is built to handle more power and reduce rotational mass, helping your rotary engine perform at its best. It's a direct replacement for the factory unit, making the upgrade straightforward.

Crafted from strong, lightweight aluminum, this driveshaft is designed to be more rigid and significantly lighter than the original. Less weight spinning means your engine can rev more freely, and the one-piece design eliminates the carrier bearing and U-joint binding that can occur with the stock setup, especially under load. This translates to a more responsive feel and improved power delivery to the rear wheels. The driveshaft comes fully assembled and balanced, ready for installation.

When upgrading your drivetrain, it's always a good idea to inspect your rear differential and transmission mounts for any signs of wear. This driveshaft is a solid choice for anyone looking to improve the reliability and performance of their FC RX-7's drivetrain.
