I just installed the GC 2.5" ARB Edition lift on my 2012 JKUR. I am looking at installing the Rock Hard 4x4 Parts JK Oil Pan, Transmission and Dual Catalytic Converter Skid Plate. Does anyone else have this configuration? If so, are there any problems with clearance on the stock driveshaft?
Rockhard claims that "Our tests have shown stock drivelines to clear this skid at 40" of flex". That is probably with the stock suspension also. So it got me wondering about installing with the lift.

I have the same lift and skids on my 2013 jkur auto and don't have any issues with the drive shaft and skids. I did upgrade to a coast 1310 right away tho. At any sort of flex the stock shaft was at its limits. And even with the coast shaft I still had to get an afe ypipe (spacers would work too) as it was hitting the crossover pipe. I would recommend getting a new shaft right away.

Keep an eye on the repezzas joint then. With the OME shocks you will have more down travel than the drive shaft can do. So you'll start tearing the boot. I also worry about the driveshaft supporting the weight of the front axle at it's limit. Not sure if that would put too much stress on the transfer case output shaft and bearings or not.

Wouldn't there be extra force from the weight of the front axle on the drive shat if the shocks where long enough to extend past the limit of articulation the stock drive shaft could do? So while it wouldn't "support the weight of the axle", I would think there would be extra force placed on the joint at the transfer case because the axle would be trying to go down more than the joint can angle.

The driveshaft gets shorter when the suspension is drooped on a short arm suspension, if anything drooping too much would cause the spline section to bottom out and push up on the driveshaft and transfer case.

I was thinking about this angle being too much and the downward motion of the axle putting too much stress on the joint. But maybe it wouldn't.
Either way, I think it sounds like a good idea to get a new drive shaft. But maybe you don't have to. I'm not an expert.
