        Comments about Rugged Ridge NP231 Mega Short Shaft Slip Yoke Eliminator Kit:

        The new tone ring is not splined and without a shim between it and the yoke, it will spin. This creates a wandering speedometer, especially under acceleration and highway cruise. The shim you need is .075thickness 1.54 ID 2.25 OD. Always use a new pinion nut (same nut as your dana 30/35/44 diff)and red loctite. Its a great kit, but get this shim and install it the first time.

            A:

            Thunder, per Rugged Ridge instructions on this NP231 Mega Short Shaft Slip Yoke Eliminator Kit, you tighten the retaining nuts to 170/180 ft.lbs.
            I hope this is what you were looking for.

          What drive shaft modifications would have to be made to make this kit work on a YJ with 5 inches of lift?

            A:

            You will need a longer length CV drive shaft. Because this will depend on your specific application, you will have to measure the the length of drive shaft needed after the SYE has been installed. Thanks!
