Tom Wood's Custom Drive Shafts - Tail Shaft Conversion Kits

Grand Cherokee DoubleCardan-Rezeppa

OEM Drive Shaft

With the original Double Cardan to Rezeppa a CV drive shaft, we have a couple of options available.

We can build a conventional double cardan (CV) drive shaft (our type A). This type of drive shaft seems to work well in applications with up to about 3-1/2" of lift. Even greater if minor vibrations are not a concern to you. This requires changing the pinion flange to a yoke. This yoke is $55.

For the CV drive shaft itself we have two different options available, depending on what you want/need in regards to quality, cost & features. Either shaft would be built brand new, complete with joints & balanced. A drive shaft built with our S spline and all premium quality components is $269. I have no concerns with this shaft in regards to a strength issue. Or our top of the line shaft, built with all premium quality components and the long travel, full length ( XC or XB) slip & spline is $299. For the long term dollar spent, I consider the latter to be the best value.

Keep in mind though, that with greater lifts or the smoothest drive shaft, our multiple double cardan drive shaft may be your best choice (four U joints). This drive shaft can only be built with our S spline. The cost for this shaft is $479. and the required pinion yoke would be $60 rather than the $55. Any drive shaft will be built with our "Gold Seal" universal joints.

We will need a measurement for the length. Measure from the flat machined mounting surface which is just inside the pilot on the pinion flange to the face of the yoke on the output of the transfer case. Or you can measure from the lip of the flange to the face of the yoke.

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. We consider the XB configuration to be the longest lasting and best value.

Note: Most drive shafts shown in photos are polished and clear coated, this finish adds $15 the cost. We only recommend the polish & clear coat for show vehicles or very dry climates.
