Don’t lower the transfer case.
You will need adjustable control arms to dial in the diff angle to go with the cv driveshaft.
Welcome to the forum. Lotsa good Rubi knowledge going on here.

 

The adjustable control arms are a must? Is this something that can be done in the future?

 

Welcome!

What Bob said. Dropping the transfer case basically negates any clearance gain from the lift. Search ROF for "tummy tuck." Adjustable control arms are necessary to set the rear driveshaft pinion angle when the drivetrain is pushed up for the tummy tuck. Most also do a motor mount lift when you do the TT so the fan blade doesn't contact the shroud.

 

If you get a decent lift it should come with adjustable control arms.

 

Lets back up.. I'm not building a hardcore offroad jeep. It May see some medium trail riding 3 to 4 times a year. Not looking to do a tummy tuck or anything like that. I want a nice riding rig on and off the road. Losing 1.5" of clearance on the xfer case is not really a big deal for me right now. I'm more concerned with vibration and wear. Just looking for an efficient way to do this without spending tons of cash.

 

As others have said, you will not need to drop the transfer case if you install a CV (double cardon driveshaft), that is one reason of installing one. Also, you will need adjustable rear upper control arms to correctly align the angle of the driveshaft. The CV driveshaft requires a completely different rear pinion angle than the stock shaft.

Tell us a little more about your rig. LJ? TJ? Build goal?
Little more info would be a big help.

 

Yeah like they said the adjustable URCA's are needed to set the rear pinion angle. However, keep an eye on the clearance between the lower shock tube and the lower spring perch when you're setting the pinion angle. Too much pinion angle caused mine to bind up on my fox shox, so I just set it as close as possible without binding.

This will solve that problem https://www.4wheelparts.com/p/currie-rear-lower-shock-mount-extensions-ce-9601/_/R-DVPF-CE-9601

There are many manufacturer's and vendors. There are also weld on brackets. I have the bolt on and been there since 2006.

 

I had JKS mounts similar to those listed above by Currie but the ARB shocks I bought would not fit inside the opening so i found something similar to the below but they bolt onto the stock location. I would take the opportunity if available and relocate the lower shock mount with a weld on bracket. That is my next step when my shocks need replacing.

 

As others have been stated - let's back up to the beginning. Have you written out a plan for your end result? As a friend of mine says to his customers... " Buyers remorse is having to pay to do it the 2nd or third time". I read you want reliability, longevity, and functionality. Simple answer is read,read,read... My first build was a year in the planning and weeks to execute. My current build was a year planning and many months in my garage tinkering - and I'm still not done. Much has changed in the last 14yrs in between builds. 1st was an 05 Rubicon... Nth Degree 6"long arm, 35's and lots of smalls. "New ride" is short arm, about 3" and many smalls... UCF skids gained 3" over stock skid w lo pro mount,Nth Degree stinger, Metalcloak arms, Synergy springs 3"F/2"R, spring relocators, AEV JK 2-3" shocks and home brewed rear lower shock mounts (style of JK). I'm happy with my progress and my Rubi gets about 20K miles a year. As for the CV shaft?.. depending on how you do the rear - longarm/short arm/stinger, make sure you measure and fit for your shaft AFTER taking all the critical measurements - extended/compressed, yoke or flange style & if you decided to run a skid plate. Best thing about Jeeps is making it YOUR OWN.

 

^^ well said ^^

What I've observed and experienced myself is we do a few mods, wheel, discover equipment limitations, do a few more mods, watch others do obstacles that we struggle on, do a few more mods, etc., etc.
