Upgrade Your Subaru With Our Driveshafts

Depending on the customization goals for your vehicle, the right Subaru driveshaft ultimately comes down to the performance or safety benefits you’re looking for. Here’s a quick breakdown of the main benefits and downsides of the Subaru drive shafts we have for sale: 

• Steel Driveshafts: The heaviest of the three, a steel driveshaft is optimal if you need to maintain a heavier vehicle weight for improved downward force/tire traction. Steel driveshafts are extremely resilient, and due to the metal density, produce minimal vibration. Although durable and affordable, steel driveshafts require more engine force to generate inertia so gas consumption increases and horsepower/torque transfer is reduced.
• Aluminum Driveshafts: The lightest of the bunch, an aluminum driveshaft provides an easy way to drop up to 10-20 pounds. Since aluminum is the least dense of the three, it’s easier to transfer horsepower and torque across the driveshaft, resulting in reduced engine fatigue and improved acceleration potential. Aluminum driveshafts are also affordable and resist weather-related corrosion/breakdown better than steel driveshafts do. The downsides to aluminum driveshafts include less tensile durability, more vibration, and catastrophic breaks that can result in sharp sections that can potentially damageSubaru exhaust systems, the transmission,  and other components. 
• Carbon Fiber Driveshafts: The ideal balance between steel and aluminum, carbon fiber driveshafts reduce vehicle weight, disperse vibrational forces,  and handle excessive torque with ease.  Since carbon fiber is composed of individual strands, it’s also the safest of the three. Instead of a sharp break that can damage nearby components, carbon fiber shreds apart in a less hazardous way. While capable of handling powerful engine loads and known for their additional vehicle safety, carbon fiber driveshafts are the most expensive of the three.
