Duramax One Piece 5″ OD Aluminum Driveshaft – 1480 Upgrade Kit – XCLB

The Duramax driveshaft is engineered specifically for 2001-2007 Chevy/GMC 2500/3500 models, delivering reliable torque transfer from the transmission to the differential. With a robust 5″ OD aluminum tube, this driveshaft balances weight savings with strength, making it ideal for heavy-duty applications. The 1480 Series U-joint, with a size of 1 3/8″ cap x 4 3/16″ span, ensures it can handle the increased torque demands of 4WD systems equipped with the MW3/Allison 1000 transmission.

One of the critical design considerations for this driveshaft is its length, specifically tailored for extended cab and long bed configurations. This precise length helps maintain optimal phasing and reduces the risk of vibration, which can lead to premature wear or failure. The 0.125-inch wall thickness of the seamless aluminum tube contributes to its durability while keeping the overall weight manageable.

• Verify the spline count matches your transmission output.
• Check for proper phasing during installation to prevent vibration.
• Torque all fasteners to manufacturer specifications for optimal performance.
• Inspect the U-joint for wear before installation.

This Duramax driveshaft is a critical component for maintaining the performance and reliability of your vehicle’s driveline. By ensuring proper fitment and installation, you can maximize the lifespan of your driveshaft and enhance your vehicle’s overall performance.
