What makes the stock passenger side axle shaft prone to breaking?

The stock passenger side axle shaft in these GM trucks is a split design. This design has a joint where two pieces connect, which can become a weak point when subjected to high torque loads, leading to breakage.

What material are the Fleece Performance TufShafts made from?

These TufShafts are made from Hy-Tuf axle shafts. This material is chosen for its increased strength and ability to withstand higher torque applications compared to standard materials.

Do these TufShafts come as a set for both sides?

Yes, the Fleece Performance TufShafts are designed to replace the front axle shafts. The kit includes the necessary components to upgrade the front axle assembly for improved durability.

About this part

Product Details

Fleece Performance is known for making tough parts for high-performance diesel trucks, and their TufShafts are a prime example of that. If you've got a 2001-2010 GM 2500 or 3500 truck with a 6.6L Duramax engine, especially if you're pushing more power or using it for heavy-duty work, the stock front axle shafts can be a weak point. These TufShafts are designed to directly replace those factory shafts and give you a much stronger setup.

The main issue with the stock setup is the passenger side split axle shaft, which is notorious for breaking when you put a lot of torque through it. Fleece Performance addresses this by providing a solid, one-piece Hy-Tuf axle shaft for that side. This design eliminates the failure point and makes your front axle significantly more robust. They fit right into the 9.25-inch AAM front axle found in these trucks, making them a drop-in upgrade. You're getting a well-built component designed to handle the demands of your Duramax.

This set is a smart upgrade for anyone looking to improve the durability of their truck's drivetrain, whether you're towing heavy loads, off-roading, or just want the peace of mind that comes with stronger components. This kit is designed to fit a range of popular GM trucks, including the Chevrolet Silverado 2500 HD and GMC Sierra 3500 HD models from 2001 through 2010.
