tcase drop maybe?

Hey everyone, I'm putting on some Bds 2" coils tomorrow to replace the BB pucks, and I've heard these springs might sit a bit tall. With that being said, do you guys think i'll need the tcase drop? Yes I know its only a bandaid but I can't afford an sye and driveshaft right now.

If so, I would like to use washers to drop it to keep the loss of clearance to a minimum. What size washers should I use?

I was also thinking I could get by with a MML, but was wondering if that would interfere with a tummy tuck in the future?

I'm excited to be able to get rid of these spacers and get some stiffer springs in. My speaker enclosure in the back dropped it back down an inch and a half and it rides horrible. I also just realized my rear shocks are blown so those will be replaced next weekend.

Thanks in advance everyone!

Washers or MML? And washer sizes?

It's doubtful you'll need then but just wait till you install and find out. I did not need to do it. Pull one of the bolts and take it down to the hardware section.

Im hoping I don't need it either. I love these springs and dropping the tcase would irritate me. OCD strikes again!

I have a brand-new set of Pro-Comp Transfer Case drop spacers (in original packaging) that you are welcome to. I live in Riverside.

Most don't need a TC drop for <2.5". If it does, it would be better to do a 1" BL + 1" MML. You could then use those two additions to tummy tuck (requires SYE as well as adjustable UCA) and a gas tank lift.

That's what I was thinking.

Desert, did you not wind up needing yours?

I put 2" BDS springs on mine and had to drop the transfer case (for now) and I installed a MML. I had to drop the T case about 3/4" to get my transfer case output and my pinion shaft within 1/2° of each other. YMMV

Well I wasn't looking to do a MML but I'm hoping I can get away with washers if I have to. Looks like were in the same boat, till we can get some sye's and new DS's

MML is better in the long run... no clearance lost and only take 10 minutes and a dremel to relocate your fan shroud. Maybe an hour max on the entire project

The problem is, I want to do a completely flat aluminum skid eventually and doing a mml may interfere with that. I may just go with the M.O.R.E mml and if it gets in the way eventually I'll just pull the mml out.

Then do the 1" BL and 1" MML. You'll need both for the tummy tuck unless you get a lo-pro mount. But it sounds like you'll need the lo-pro anyway if you want to go completely flat. Either way, the BL+MML is a good mod that opens doors for future mods to spend money on.

Oh, by the way... you shouldn't need to put too many washer on if they are needed. I have 3 stacked up for each of my bolts with a 3" lift and BL+MML. They are only temporary until I have the funds to get my SYE parts (SYE, CV DS, adjustable CAs, UCF ultra clearance skid, outboarded shock mod, adjustable rear track bar, and yes... the lo-pro mount). My TC is dropped less than a 1/2" but it is still my weak point that tends to get caught up on rocks when wheeling. My hope is to have it all done by next spring.

Same here, and yes I was going to go lopro and go completely flat. If it interferes I'll just take the mml off eventually. Looks like I'll be doing an mml as well. Do I need the BL to do the mml? I'm thinking I don't but I could be wrong.

Worst case I drop the tcase with some washers and save up.

A MML doesn't need the BL and a BL doesn't need a MML. They just make it easier since you won't have to modify the fan shroud.

So if I did the mml what are the chances I would still need to drop the tcase?

I'd guess there's still a 1% you'd need a TC drop with a MML. It all depends on how much lift you get out of the springs. My Savvy/Currie 3" needed about 3/8" drop with MML. I know of one person with Zone 3" springs and MML that didn't need a drop at all and one needed a drop with the same setup. Sucks having to guess doesn't it?

I didn't need a drop. Derp, wana do something cool? Buy leveling spacers for the front (.75") and do the mml/bl. If you still have vibes try throwing the leveling spacers in. You'll like it anyways to compensate to droop from a winch and to get rid of the factory rake. It actually lifts the front of the jeep and will help with the angle of the drive shaft ever so slightly. It can be enough to offset vibes in some cases. I have done the math and discusses this with other members and have seen the pattern. It would be interesting to see how it actually would work for someone like you.

Anyways I'm with ^blk, a mml really helps a ton. I got rid of a 3/4th inch t case drop thanks to mine.

Looks like the MML is on my list for this coming weekend. As for those spacers I have some 2" spacers maybe I'll cut them down to .75"

I'll be doing the coils with a mml next weekend then drop the tcase if I have to and I'll level the front off. Sounds like a plan?

Yes!!

I recently installed the BDS 2 inch lift and I DID need to drop my Tcase due to minor vibes. Two washers all the way around was a quick and cheap solution.
