Rubicon t-case drop

2003 jeep wrangler rubicon 4.0 6cyl 5 speed Dana 44 axels front and rear. 4.10 gears 33" tires on 16" rubicon rims 1.5" wheel spacers. 4" fabtech lift. With the 4" fabtech lift or 4" lift in general on a rubicon how much should I drop the transfer case? Thanks

From the threads I have seen, you need to get a SYE and double joint driveshaft with 4 in lift.

Rubicon a don't need sye. Also things I've been looking into is body lifts motor lifts. I eventually plant to get a rear drive shaft. Don't want to buy control arms cuz I plan to change my lift year or two down the road.

I thought it was LJ's that didn't need an sye, what makes a Rubicon immune to needing one...just curious

They've got a different transfer case than a stock tj. It's got a fixed yoke already, I believe.

Rubicon's don't have a Slip Yoke...so there is nothing to Eliminate (aka SYE).

Rubicon also has CV driveshaft. No need for Xfer case drop.

If I recall correctly, they do not come from the factory with a double cardan driveshaft.

This is a stock Rubicon's shaft...




This is an aftermarket Double cardan (CV).







And our non-Rubicon typical Slip Yoke driveline:

Rubicons have a fixed flange output and came stock with a single cardan drive shaft.

OP, you can just use a few washers on each of the skid plate bolts to drop the t-case. Experiment with a 1/4" drop and see if it stops your vibrations. However, the best bet is to just buy a CV shaft. Tom Woods has a new 1310 series CV for $299 shipped.
