How to properly and accurately find your slip yoke measurements.

A driveshaft slip yoke is a crucial component in a vehicle's drivetrain system. It's a mechanical connection point located at one end of the driveshaft, usually, the end that connects to the transmission or transfer case. The slip yoke is designed to allow for the dynamic movement of the driveshaft as the vehicle's suspension articulates and the drivetrain components flex. It consists of a splined shaft that slides in and out of the driveshaft, accommodating changes in driveshaft length during suspension travel. This flexibility in the slip yoke helps prevent binding or damage to the driveline while maintaining a solid connection between the transmission and the differential, allowing power to be transmitted effectively from the engine to the wheels.

Being precise when measuring your slip yoke is very important! Measurements should be provided to the nearest thousandth (0.001) and gathered using calipers.

We highly recommend using calipers to gather your measurements for your slip yoke. Using calipers is important for accurate and precise measurements. Calipers are precision tools designed to provide precise measurements.

U-Joint Cap Size

Using your calipers, measure the inside diameter of your u-joint caps. This will provide you and us with one of the two measurements to find what style u-joint you have or need.

U-Joint Width

Using your calipers, measure the distance between the outside holes for your u-joint caps. This will provide and us with the second of the two measurements to find what style u-joint you have or need.

Slip Length

Using your calipers, measure the total length from the splined end of your slip-yoke to the center of the u-joint holes.

Spline Count

Looking at the end of your slip yoke opposite of your u-joint, count each spline in your slip yoke. Beware of dead splines, which is an extra large gap between two splines. If you have 26 splines with 1 dead spline, you technically have a 27-spline slip yoke or 26/27-spline.

Bore Diameter

Using your calipers, measure the diameter of your slip yokes shaft.

• Recessed splines
• When the splines of your slip-yoke do not go all the way through your slip-yoke shaft and are slightly recessed
• On some vehicles, this does not matter, on others it does. Contact us for more information

• Balancer or Harmonic Balancer
• This is a feature more commonly found in older vehicles and in most cases they are not needed with today's slip-yokes
• Appears to be a flat plate or weight built into the base of your slip-yokes shaft
