I have my stock springs, pitman arm and everything. I got about 5" out of it, also got bigger shackles; I'm running 35" baja claws with room left over

Pretty sure a transfer case drop is needed for the SOA conversion.

junk the rear track bar....gonna need longer shocks and brake lines, dropped pitman arm, and tcase drop

longer sway bar links are not needed since it will bolt on top of the plate instead of under it

if you're spending the time and money on SOA, go with a SYE and not a tcase drop.

i had to relocate brake lines, drop pitman arm, new spring perches up front, shocks of course, among others.....

oh yeah, i had to extend my front drive shaft....but i stretched the wheelbase a smidge.

i guess i just dont see the point of putting a lift on it if you're not trying to try to increase the ground clearance

Slip yoke eliminator....basically it puts a bolt on yoke on the rear output of the transfer case instead of the slide in one you have right now. The kit isnt cheap, it can be a pain to install, and you have to use a stupid CV driveshaft with it.

it also shortens the tail end of the tcase so you can run a longer shaft with less angle. im running a front shaft (CV) off an XJ i got for cheap and then shortened.

also, if you break a rear driveshaft, you can just unbolt it and limp home. whereas with the slip yoke, all your fluid will pour out if you dont rig it up.

Buildembig-Are you running stock springs? How big of springs can you run without switching to SYE? My YJ is still spring under with 4inch springs because I can't afford the HIGH price of the SYE/CV. I do have a set of brand new stock springs and SOA brackets and my t case already has 1" drop. But I've been waiting until I could get the sye.

I won't ever use a SYE and a cv shaft....cv's are weak and a pita to repair. If I go up that high I swap the case out to a NP205 or an Atlas with a 1410 output yoke and go on. The biggest I have went with a stock NP231 case is a 2.5" spring on a SOA...so basically 8 inches of lift. I dropped the case down 1.5" as well as rotated the pinion up on the rear end before I welded the perches on. My advice to you if your not making a crawler would be to swap out the case with something else, use your 4" springs on the SOA and rock on

Just for reference, I had 6" rearched springs on top and ran a Np205 transfer case with no drop and never had an issue.

im not trying to bust your chops here (really, i'm not) but you give reasons not to put a SYE on as they're expensive and a pain to install. then you suggest instead to swap tcases to an atlas ($$$$) or np205 ( which is going to require some sort of adaptor or a tranny swap as well)? i dont follow your reasoning here.

i'm going to disagree with the cv shaft being weak also. we're not talking swapping in tons etc. of all my driveline carnage i've suffered, the double carden has held up....and im running 1310s.

maybe the difference is i play in rocks....and im guessing from the heights you're talking about, you either play in mud or on the street (not saying that negatively)

No offense taken

Basically what I was saying is that for a standard SOA with stock springs up to 2.5" springs I feel there is no need for a SYE....anything over that I would swap out cases since the reason for larger lift is to run larger tires, and I wouldn't trust a 231 case on anything larger than a 35....but it is possible to lower the case enough and rotate the pinion enough to not need a SYE...or just find a case out of rubicon and bolt it in.

My opinion on CV shafts has been a product of messing with Ford trucks all my life. Most of the shortbed trucks in the 70's used cv shafts in the front and they always blew apart even with a stock M motor and 33's...I started making my own 2 joint shafts about 12 years ago and haven't looked back since. I have found that with a 1410 series joint I can get more angle than a CV with 4 times the strength...and the joints are only 16 bucks since they cross ref to a 1000rpm pto shaft from a tractor. The one inch gain from using a SYE versus a t-case drop is no way cost justifiable to me. But then again, people will spend 2200 bucks on a tummy tuck and cut the body up, versus using a larger lift to run the same size tires...and thus having the option of taking it off for resale.

That being said I build all kinds of rigs for all kinds of purposes...I have a truggy that I built specifically for trails and rocks, but most of my jeeps are made for light duty or street. Since I sell jeep parts to suppliment my income, a jeep is worth way too much to me in parts versus beating the body up in the woods.

fair enough. i look at the drop kit as a bandaid approach, but like you said, if you're not flogging on it then it doesnt make much difference i suppose.

i havent had any bad experiences with double carden joints (including on my diesel) but, bad experience is bad experience and i wont argue with you there. i've had several experiences that were opposite of "the book" and hard to justify

makes sense

damn sure makes sense and i'd be looking at it the same way. like you said, just different ways of doing things

Well in my case yes.. My dumb azz decided to ditch my 3" bodylift and make it up with a SOA conversion.. Of course i did it with my 4" springs though since i just bought them....... Way to high now and both my front and rear shafts are to short..
