T case drop or Slip yoke eliminator?

I'm planning on getting the rough country 4" lift and a set of 33's for my 97 TJ. I'd like to hear some of the arguments as to why I should drop almost another grand on drive line angles vs fab up a cheaper t-case drop bracket? Are there any horror stories from someone who took this short cut? Like drive line vibration and what about hard shifting with a manual transmission? I've read the write up about this lift kit by a 4x4 magazine and they went with slip yoke eliminator. But I recall my dad's old cj had a fabricated bracket. I guess I'm looking for some real world experience and I'm grateful for any advice, link's, pic's, video's.

Why would you lift your rig then lower the transfer case and lose ground clearance? I'd suggest buying an SYE, CV Shaft, adjustable rear upper control arms, and a high clearance transfer case skid.

If you plan to just drive your rig on the street then by all means use a transfer case drop and keep the stock shovel.

Yes, SYE would give you more clearance, but remember that with a sye you need the SYE, a CV driveshaft, and adjustable control arms in the rear. With a tc drop all you need are the spacers. Its much cheaper but you lose clearance.

I normally don't buy something just to throw it away. Why not just lift 2.5"SL and 1.25"BL and not have to worry about either and still fit 33's.

I'm with him...

Also what are you planning on doing with your jeep? I take it that if you can't see the reason to do the SYE then you really don't need it.

Do it properly mate , mine had 2 inch Suspension lift and trans lowering kit, and the slip yoke bound up at full stretch and a heavy foot, snapped output shaft just inside the transfer case and blew the lot to bits.
Had to get new trans case, oil pump,bearing kit seal kit, SYE, Drive shaft, and a whole lot of other bits, Cost $2000 New Zealand dollars and 3 months off the road waiting for bits to arrive.

I also have now got a modified 92 Toyota hi-Lux rear drive shaft, instead of the double cardan one recommended, was way cheaper to get nade up $180 NZ compared tp $520 and I feel it's better. Less uni joints to worry about fixing in time and has plenty of movement in yokes so won't bind.My lift is only 2 inch though but set up as it is now would do a 3 inch easily still with room to move

Yes. You can not properly set your rear pinion angle with adjustable UCAs. adjustable LCAs may also be required.

The plan for the jeep is to see all the orv trails in Michigan and use it as a daily driver for the next year. I really don't want a body lift because it doesn't offer any ground clearance, upper and lower adjustable control arms is a must, but I had considered lowering the t-case and sacrificing ground clearance to save a bit of money. That is until I look at Wrnglr's pics. I even looked at the exchange rate to see how much this would have cost me. It's not a fun fix that's for sure.

Just do it right. Once the money is spent, you won't miss it and you'll have piece of mind. That was the realization that I came to. Plus it's one less thing you'll have to do later.

ETA....If you spend a little more and get the Xseries lift, it comes with adjustable control arms, track bar, quick disconnects, etc.... You won't have to spend that money twice either.

T-case drop is a bandaid that may or may not work. Meaning you might still have to have adjustable control arms. The SYE will go further to fix vibration problems, and is the correct fix for drive shaft vibrations due to lift.

Basically, either way you go, you'll need adj control arms to do the job correctly, but the SYE won't sacrifice ground clearance that you installed the lift to gain.

You're not thinking this one completely through....while a small body lift doesn't raise the frame up, it offers you room to gain clearance where it matters--at the belly.



And you can't gain that kind of clearance while retaining the stock slip yoke rear output.

I am with the rest of the people. I would do it right or not at all. If you are on a budget I would go the BL and smaller lift to fit 33s. Just my 2 cents.
