one inch riser motor mounts after suspension lift?

My '88 YJ has a 4" RC suspension lift from the prior owner. My motor mounts are shot, and i am looking at replacements. Would i benefit from these lifted ones or should i just use the stock replacements. My transfer case is already hitting (in fact resting on) my lowered skidplate. Do i have to get support under the motor if i only remove one at a time?

Your trans mount has to be shot. Even with my 1" mml and transfer case drop I never had my transfercase hit the skid. Get a new poly trans mount. As far as engine mounts you can maybe squeeze a 1"mml in with stock body mounts but you really need a 1" BL to keep some firewall clearance..

In short, the clocking on his tcase is not standard.

I thought I saw that pic before! Thanks Joe. I'd get that clocked up and off that skid then. A MML will make it even worse.

If you are thinking that raising the engine will help with the tcase rubbing issue - wrong. You'll make it worse.

Take a second & think about it.

Your engine is set in place by it's motor mounts & the tranny has its mount (yours is dropped).

Since the tcase is past the tranny, the tcase will tend to get lower if you raise the engine up.

Yes, you should support the motor with a floorjack (or something similar) while replacing the motor mounts. I like using a block of wood under the oil pan. And yes, replace one side at a time but loosen all the bolts (do not remove all at once) so there's some wiggle room.
