Technical Details and Specifications
This Dorman drive shaft (part number 946-157) is designed specifically for Dodge Ram 2500 and 3500 trucks, ensuring proper fitment and driveline compatibility. The aluminum shaft material reduces rotational mass, which can contribute to smoother operation and improved fuel efficiency compared to steel alternatives. The 5.75-inch diameter and 0.108-inch wall thickness provide structural integrity to handle the torque demands of these heavy-duty trucks. The included slip yoke facilitates a secure connection to the transmission or transfer case, although CV joints and axle nuts are not included with this part. The drive shaft length is fixed at 85.5 inches, so it is important to verify compatibility with your vehicle's specifications before installation.

Installation Notes and Tips
When installing the Dorman 946-157 drive shaft, ensure the vehicle is securely lifted and supported. Verify the drive shaft length and diameter match your Dodge Ram 2500 or 3500 specifications. Since this drive shaft does not include CV joints or axle nuts, reuse existing hardware or source replacements as needed. Proper alignment and torque specifications should be followed to avoid premature wear or driveline vibration. This drive shaft is not greaseable and has a fixed length, so no adjustments are necessary during installation.
