you dont NEED an sye kit
there is a flange for the yoke on the 8.8 that excepts your ds ujoint
do a google search for it, its like 20bux

For 4"? Unless he's a mall queen, he's gonna need an SYE. That slip yoke will pop right out pouring ATF everywhere. I have a 1.5" suspension lift and my yoke is 1-2" further than stock.

My $.02

if you dont do a SYE now and end up wanting to do one later you're going to have to grind off your perches and reset your pinion angle.

you might as well do it right the first time

It's funny that a lot of us speak these words with experience of the contrary. I can tell you that experience has taught me to look st the entire build and not just the nickle and dime upgrades. It costs money to redo something and it doesn't make you feel very smart either...

I agree. Take the time to step back and think of where you want the build to go. Look at the long term instead of fretting over dimes and nickles. If you cheap out and do the quick cheap fix and brake something youll end up spending more to fix your earlier decision. I did a SOA swap and did not get a cv joint when i first had drivelines rebuilt..i ended up having to pay more to get the driveshafts rebuild to accept a cv....major PITA

I think we're all guilty of, at one point or another, muttering the phrase, "It's good enough". It almost never is, and you always regret saying it.

Experience has shown me that it's better to wait an extra few weeks to get more money to do it right, rather than jumping the gun and having to fix it and spending more money than the difference in the parts you wanted.

Not to say you always have to pay big bucks, but make sure you have what you need, and just research it.

I don't have the cash. And it would be a waste of it anyhow. I'm doing a V8 auto trans swap hopefully before thanks giving (jeep will be paid off in Oct ) and its only been like that sence chfistmass so I'm good on the three year deadline?


Sorry bro didn't mean to heist your thread.

ive heard that you can have a xj front shaft with the cv shortened to match whatever length id need...? have any of you done that ? ....... my truck has a 4 inch rc lift and a 2 inch tcase drop the shaft angle isnt bad atall... my boss said its just shy of a stock angle ... also my shaft sits only about 3/4 of an inch out of the tcase .... i know that i should do the sye but this is my daily and i cant have it out for too long being that the process is allready started... the sye will be done asap but it cant be done at the moment... college student... funds are scarce...... i have been wheeling the truck pretty hard as is.. rausch creek offroad park on black trails and no problems with the shaft popping out

Anticanman runs the XJ front shaft, and when I do my SYE install, I will as well.

I also use a cut down XJ shaft.

When you're ready to do the SYE, pull the t-case drop, and measure after the SYE is in and have the shaft cut.

If you need the flange, I got mine @ Denny's for about 28. It's the large one, the smaller one is for the mustang 8.8s.
