Sye/cvd

what is SYE/CVD. I was reading threw the lift reviews and saw that. Also why do you need a t-case drop with all lifts?

When you lift the suspension AND transmission that effects the angle of the drive shafts because the differentials are staying at the same height (granted going up in tie size they raise a bit). The greater the angle the higher chance of drive line vibration. The jeep is an inherently short vehicle so its worse with jeeps. In some cases the transmission has to be lowered to correct the vibration. With a sye the angle of the drive shafts is not critical. So there its no need for at case drop Someone else more knowledgeable can probably explain why

Sye because with t case drop you lose ground clearance

that is true, so exactly what does a sye look like, and where do you get one from?

any jeep parts seller will have them.

Let me google that for you


it shortens the tcase which allows you to have a longer ds meaning less angle. you can buy a custom CV driveshaft or i bought a front shaft off an XJ on ebay for 40 bux and had it shortened.

edit: $180 on flea bay http://cgi.ebay.com/ebaymotors/87-06...d=176839745444

haha. i've been looking for an excuse to use lmgtfy. you were just a target of opportunity.

i took off my tcase to install mine. some do it on the jeep. its easy enough to install. (and worth it IMO)


ibuildembig prefers drop tcases instead (what he was referring to)
hes a chucklehead though (just playing with you man )

Because to me I'd rather spend 25 bucks and lose an inch that's prolly not gonna matter 99 percent of the time anyway; versus spending 200-500 on something I have never used in 13 years of doing jeeps and don't see the immediate need for To me, if your gonna get that wild in the woods you need a different case all together....but that's just me yanno
