Driveshaft Shop Drive Shaft

Fitment: 2004-2007 Subaru WRX STI

Part #: 610098

Overview

The Drive Shaft Shop 1-Piece Carbon Fiber Driveshaft is a high-performance upgrade designed specifically for the 2004-2007 Subaru WRX STI. Crafted from a 2.75-inch diameter high modulus carbon fiber, this driveshaft offers a significant reduction in weight compared to the factory two-piece shaft—approximately half the weight—resulting in improved rotational response and overall vehicle agility. Its lightweight construction helps enhance acceleration, throttle response, and handling dynamics, making it an ideal choice for enthusiasts seeking to optimize their Subaru’s performance. The one-piece design eliminates the flex and potential failure points associated with the stock two-piece setup, providing a more direct power transfer and increased durability under high-stress conditions. Whether you're building a street performance car or a track-ready machine, this driveshaft supports your goals of faster, more reliable driving.
