hey yall im about to buy a SYE for my 97 jeep tj with 4" lift. so im thinking the standard HD SYE from advanced adapters is the way to go. If ya think there is a better reason I should buy a different one speak now or for ever hold your peace. ha I know ive talked about it before but just wanted to ask again. thanks !!

That's the one that I bought and I have not had any issues with it. I think the only bit of advice is if you think you may ever do a tummy tuck, get the super short SYE.

I had the SYE from Advance Adapters with my 4" lift but I could never completely get rid of the vibes unless I dropped the TCase about .5" to 1". After I upgraded to the Supper Short SYE I never had any more vibe issue with the old 4" lift and even now with my 6".

The only downside with the Supper Short is that the speedo is electronic so there are no gears you can change to calibrate it. All you can do if use an electronic speed calibration.

I always recommend the Advanced Adapters SYE. I used it on my old Cherokee and it was great.

Of course these days, I think you can't go wrong with any of the reputable brands. Hell, I might reach out to Tom Wood and get an SYE from him. He's not going to sell you anything bad!
 
well sounds like we are in the same boat so ill look into the super short. which brand did you use and what CV drive shaft did you go with?
I think it was the Teraflex one. I have been using Tom Woods driveshaft since I upgraded the from OEM.

Tom was the one who told me that I should have gone with a Supper Short SYE. It was after I had given him the angle and measurement get my driveshaft made. I had already installed the Advance Adapters SYE so based on the angle he said it could possibly bind or give me some vibes. He was right. I kept the setup for a couple of years then upgraded to the Super Short SYE.

I've never heard of a bad SYE kit, they all seem to be fine. Personally, I installed a standard length SYE into my previous TJ and for most of us, I don't believe a super-short is necessary unless you're also going with a tummy-tuck or extremely tall suspension lift. Not to mention with a conventional SYE you can continue using speedometer gears to calibrate your speedometer. Super-short SYE kits get rid of the speedometer gear and you have to buy an electronic speedometer calibrator.

Give Tom Wood at www.4xshaft.com a call. Tom sells SYE and CV kits with everything you need. He'll work with you to make sure you get the right setup together with the right length CV driveshaft. I've worked with Tom probably 16 years and have never talked with or met a nicer guy. Patient and an expert in all things to do with CV shafts, driveshafts, and SYE kits. Please tell him I sent you and request to speak with Tom personally. His staff is good but Tom is the guy to talk with. If Tom doesn't answer, tell whoever answers to tell Tom that Jerry Bransford sent you and he'll pick up the phone or call you back.

Absolutely agree here. He is a great guy to deal with and will not steer you wrong. If you call and he is not available he will definitely call you back. 2 good friends of mine who have been part of the Jeep community for a long time recommended Tom Woods to me many years ago. I was also able to meet him in person on my 1st trip to EJS back in 2012 at his booth. Nicest guy you will ever meet.
 
I'm in the middle of doing a SYE now. Went with the standard AA kit. Got the best deal from Ryan at Northridge4x4. At 3" of lift and no TT, I'm hoping the standard SYE will be ok.

I ended up with more than 4" of lift with my Currie springs and the standard SYE was just fine.

Check out the HD shorty from JB Conversions it's nice. I had the regular sye from Advance Adapters but switched to the heavy duty short from JB conversions.

Hey, when will yours be complete? Id like to know what the outcome is as far as vibrations go and also when you roll the pinion up to point at the output shaft of the transfer case how close did your shocks come to hitting your spring holders? or did you put the spring perch extenders from Currie on to relocate the shocks?

Just invert your rear shocks so the skinny strut is at the bottom. That will give you the clearance you need and is what I've done for 14-15 years since installing my CV driveshafts. Most shocks have no problem running that direction, I've run probably five different shocks inverted in the rear without problem.
 
i just got off the phone with Ryan at Northridge 4x4 and he said start with the sye and cv first then after removing the transfer case lowering kit you still have vibs to put a motor mount lift on and it will get rid of the vibs for sure.
my question to you is do you have to do a 1" body lift in order to do a motor mount lift.

Got a question on flipping the rear shocks...what do you do about the bar pins in the rear? Those usually don't come out easily and without tearing the bushing up. Just curious.

Ryan doesn't sound like he knows much about what he's talking about. There's no reason you would need a MML after installing a SYE and CV driveshaft to get rid of vibes. Properly installed, there will be no vibes after installing a CV driveshaft when you have the axle rotated properly to give the correct pinion angle.

Even if you had a MML there's no reason to install a BL. Installing a MML raises the engine fan about an inch. All you need to do for the fan shroud to clear the new higher fan position is remove the fan shroud and reposition it up an inch higher by drilling new mounting holes in the shroud 1" lower than the factory holes.
