HOW DO I MEASURE MY DRIVESHAFT?
When ordering a carbon fiber driveshaft, you want to make sure you have the correct dimensions for your vehicle. The diagrams below will help you get the right measurements for ordering.
***The first thing to do is make sure the vehicle is at ride height when taking your driveshaft measurements. All measurements must be within 1/16”.
MEASURING YOUR DRIVESHAFT ASSEMBLY:
A – Distance from the center of the front U-joint to the center of the rear U-joint. Take this U-joint center-to-center measurement with the slip yoke in its operating position. The slip yoke operating position is typically determined by pulling the slip yoke out of the transmission 1” after it’s fully bottomed out.
D – Distance from end of slip yoke to center of front U-joint.
MEASURING YOUR DRIVESHAFT ASSEMBLY WITH REAR FLANGE YOKE:
E - Distance from center of front U-joint to end of flange yoke.
D – Distance from end of slip yoke to center of front U-joint.
DETERMINING LENGTH WHEN YOU DON'T HAVE A DRIVESHAFT TO MEASURE:
A or E are required measurements for ordering a driveshaft. This is because of variations in transmission type, where the barrel of the slip yoke may or may not bottom out inside the transmission. If you don't have a driveshaft to measure, you can determine A or E by measuring with the slip yoke that you'll be using. If you need a sample slip yoke for measuring, please contact QA1 at 952-985-5675.
