Topic: Is a sye & drive shaft needed for 4" lift on a TJ ???

[lax22]

4 inch will not look whimpy. What you also have to remember is that having a 4 banger you also have less weight up front. So when you add a lift that is designed to compensate for the extra weight of a six cylinder, you end up getting a little more lift out of the front end so you can get away with a little bit larger tire. I Bought my jeep with a 4 inch superlift already on it. Yes it dose have the spacers not the SYE, but if i could do it over i would get the 2.5 old man emu with a 1 BL. IMO Just the right ammount of lift so you can easily fit 33's and not look whimpy at all

Get a hack and tap Rubicon Express SYE with a CV RE driveshaft. Way cheaper, and with a 4 cylinder the output shaft doesn't need to be any stronget than it already is with up to 33 in tires.

The hack & tap RE sye look alot different than other kinds, it doesnt look like they have a new shaft with them either, do they work??

Does anyone have pictures of one installed?  Does it make the output any shorter or does it just eliminate the slip yoke?

You replace the output cone so the transfer case is shorter as well as eliminates the slip yoke.

Thanks.  I found this link too.

I don't know, looks like the spline engagement gets reduced too much.

I just looked at the hack & tap install linky...

Thats not for me, I will just order a regular sye if I need one.

The reason for that length is because that's what the yoke rides on.  You meed a minimum of 2" or so for the yoke.  Since the new yoke won't be moving, it's fine.

Also, if you own a YJ, don't buy a hack & Tap.  YJ's don't have the rear seal in the housing so the Hack & Taps are usually $100 more then the TJ kits.  Strength wise, I've never heard of anyone having trouble with any of the SYE kits.

Unless you're like me and have dozens of TJ mainshafts and tailhousings sitting around to use with the H&T.

My H&T works just fine, but it's a little longer than the HD SYE kits.

Collecting them I see... 

The length of the SYE's used to range from 5.5"-4.5".  Then you have the super slim that give you another 2".

Leftovers from all the SYE installs, spare parts never hurt
