Measuring Your Jeep Wrangler TJ Driveshafts
TJ Wrangler Front Drive Shaft
For the Double Cardan (CV) drive shaft we have two options available. Either drive shaft will be built using upgraded heavy wall tube, larger/stronger slip yoke & spline stub and our “Gold Seal” universal joints. With our S spline, the drive shaft is $299.00. Our top of the line shaft with the longer travel X spline with XC or XB slip yoke is $319.00.
Stock Type TJ Rear Drive Shaft
We can build a new stock type drive shaft for your Wrangler for $219.00. We will need the length measurement taken from the vehicle with the drive shaft removed and the vehicle sitting normally on flat ground.
Double Cardan TJ Rear Drive Shaft
If you have substantial lift and want the smoothest drive shaft, we suggest one of the Slip Yoke Eliminator (SYE) kits along with a double cardan (CV) drive shaft.
This is the best type of rear shaft for any lifted TJ Wrangler. It corrects problems associated with increased drive shaft angles on lifted Jeeps. It will require that you install a slip yoke eliminator kit.
With this system there is no need for transfer case drop spacers. You will however need to rotate your differential so the pinion points directly at the out-put of the transfer case to maintain minimal joint angle at the differential end. This is typically achieved by adjusting your rear control arms.
If you have questions about proper drive shaft angles or need help determining the correct amount of adjustment take a look at our angle measuring guide. Or you can give us a call.
If you will measure the slope of the drive shaft and the slope of the pinion, we can calculate any adjustment that may be needed.
We have a number of complete package options available which include the SYE and drive shaft. These range from $525.00 to $750.00. If you are interested in all the different SYE options, give us a call.
For the SYE Kit and Drive Shaft package, we just need the length measurement.
If you are ordering online, are ordering the Advance Adapters SYE, and want to order the shaft at the same time: subtract 3" from the measurement below. This way you can figure your drive shaft length without having the SYE installed. For example, if you measure 19" as shown in the photo below, subtract 3 and order a 16" drive shaft.
Spline/Slip Yoke Differences
The S spline is a conventional spline stub that will yield a safe, effective and usable stroke of 3”. The X spline is longer than the S spline. The X spline is cut for the full length of the spline stub. This gives a bit more than twice the contact area between the slip yoke and spline stub and a stroke of 4-1/2". This in and of itself will net more than twice the life on these two components.
With the XB configuration, we will use a heavy rubber boot which is banded down with stainless steel banding to seal all of the contaminates out and keep the grease in. The XC configuration uses the same slip yoke & spline stub but instead of using the rubber boot, we drill and tap the slip yoke for a grease fitting and use a dust cap which has convolutions that follow the spline stub for sealing. The XB is best for wet and dirty conditions. The XC is best for rocks and extreme wheeling.
