If you want to reliably transmit power through your Wagovan driveshaft, you need to upgrade to 1310 U-joints.
We know it can be very frustrating and time-consuming sourcing all the needed individual components, so we’ve put together a kit to make things easy!
Includes everything you need to upgrade your Wagovan driveshaft to 1310 U-joints (minus tubing) to withstand the demands of high horsepower applications and provide reliability that cannot be achieved with your weak and worn out tiny original Wagovan u-joints. This kit has been tested and proven on our own 1400+whp race car running mid 7’s at 193+mph.
Simply bring this kit to your local driveshaft shop along with your Wagovan driveshaft and they can build and balance your driveshaft for you. You will need to have your viscous coupler and rear differential already mounted in your car so that you can give them the length measurements needed (transfer case to viscous coupler for the front driveshaft length and viscous coupler to rear differential for the rear driveshaft length).
Includes EVERYTHING you need, including our SFR Honda AWD Billet Flange Adaptor Kit!
SF-05-531 KIT Includes:
x1 SF-05-531 Front Flange Yoke (bolts directly to B or K Series transfer case output flange and utilizes a 1310 u-joint to front of Wagovan driveshaft)
x1 SF-05-535 Front Tube Yoke (Weld to the front of the OEM Wagovan 65.0mm OD x 1.6mm wall = 2.56″ OD x .063″ wall driveshaft tube that has the slip joint on it. Your driveshaft shop can easily step down the shoulder diameter by ~.070” to fit inside the Wagovan tube)
x2 SF-05-530 PTO Flange Yoke (for rear viscous coupler flange & diff flange, will need SpeedFactory Racing Billet Flange Adaptor Kit to center flanges)
x2 SF-05-533 Rear Tube Yoke (these will be welded to a new section of 2.5” OD x .083” WALL DOM steel rear driveshaft tube, supplied by driveshaft shop)
x3 SF-05-532 1310X Non-Greaseable U-joint (non-greaseable units are used because they are stronger than greaseable ones)
x1 SF-05-510 Billet Flange Adaptor Kit (x2 billet flange adaptors and hardware)
