Put the power through your driveshaft reliably by upgrading your U-joints to 1310's with the help of our Flange Adaptor Kit. 

Stock Wagovan driveshaft U-joints are tiny and weak, these flange adaptors allow you upgrade to 1310 U-joints to withstand the demands of high horsepower applications and provide reliability that cannot be achieved with your weak and worn out old original Wagovan u-joints.

*These adaptors go on the REAR driveshaft tube section in between the viscous coupler & driveshaft and in between the driveshaft and rear differential.  To upgrade all of your U-joints including the front one directly off the transfer case please see our complete conversion component list below to help you. 

Product Features:

  • x8 High Strength Grade 10.9 bolts, stainless steel washers, and Nylock nuts to prevent loosening due to driveshaft vibration and harmonics
  • x2 Precision CNC machined 6061-T6 billet aluminum flange adaptors
  • Black Anodized finish adds durability and eliminates corrosion
  • Laser-etched SpeedFactory Racing logo


Supply this list to your driveshaft shop along with your Wagovan driveshaft and they can supply these components when they build the new rear 2.5” diameter driveshaft tube section (from the viscous coupler to rear diff) as well as swapping the front tube yoke. You will need to have your viscous coupler and rear differential already mounted to give them the length measurements needed.

Wagovan Driveshaft 1310 U-Joint Conversion Component List: 

x1 Neapco N2-2-899-1 Driveshaft Flange Yoke (bolts directly to B or K Series transfer case output flange and utilizes a 1310 u-joint to front of Wagovan driveshaft)
x2 Spicer 2-2-329 PTO Flange Yoke (for rear diff flange and rear viscous coupler flange, will need SpeedFactory Racing Flange Adaptor Kit to center flanges)
x3 Spicer 2-28-367 Tube Yoke (x2 of these will be welded to your new 2.5” diameter .083” wall rear driveline tube, x1 will need to be turned down a bit by your driveshaft shop to fit inside the front of the OEM Wagovan driveline tube that has the slip joint on it)
x3 Spicer 5-1310X Non-Greaseable U-joints (non-greaseable units are used because they are stronger than greaseable ones)



This can all be very confusing and hard to visualize until you've actually done it! Below is a basic component flow path to help you understand what components go in what order, starting at the front of the car and working towards the rear.
