Standard SYE or Mega Short?

So I'm in desperate need of an SYE/CV. I'm lifted 4" w/33's. My rear shaft is at about 26deg. The ONLY time I feel no vibes is with a full tank of gas and the back seat being in. So I figure, if I'm saving the money for an SYE & CV, should I save even more for the Mega Short? Is the mega really that much more advantageous? Mega short = more $$$, and the longer CV shaft = more $$$.

I beg to differ. Everywhere I look, the mega shorts seem to be about $100 more. And can anyone explain the speedometer issue to me? Is the mega short w/o the speedo gear?

Speedo gears can be expensive these days. They are no longer $15-20 at the dealer.

The super short SYE might be cheaper in the long run if you do a few tire and/or gear ratio swaps.

Do you plan on doing a tummy tuck someday? That is another potential reason to push you towards the super short SYE.

with the super short SYE you can use a speed-o-healer to calibrate for your tires and gear ratio. so on top of being an extra $100 for the super short, you will need a way to calibrate your speedometer.

i figured it was around an extra $250 for the super short. and i wouldnt think that a 3" difference in length would cause the drive shaft to be any more expensive. most are built to order anyway.

the extra few inches will make a differnce, but how much... i dont know. (thats what she said)

you can also look into high angle driveshafts

The JB super short SYE is calibrated for 35" tires and 4.56 gears.

The other super short SYEs are probably the same, but I do not know for sure.

I was lucky and didn't need to calibrate my speedo since I'm running that combo. I wired it in and it worked accurately.

are you sure on that???

from the website...

The speed sensor supplied in the kit produces the stock Jeep signal allowing the original speedometer to function normally.

am i misreading it or are they clamining that its the OEM tooth equivalant?

what gear would be required for 35s and 4.56? vs OEM?

I don't plan on changing the tires at all. 33's are big enough for me. As soon as they begin to look small, I just go price some bigger ones, and the 33's look great again

As for gears, I'm not touching gears until I have to put a new rear axle on. This D35 is gonna pop eventually. Hopefully later, than sooner ($$$).

I doooooo plan on a tummy tuck. I think they not only look great, but the functionality makes sense. And my belly pan has taken some hits. Yet another reason I need an SYE.

HAAAAAAAA!!!

So just to be clear, I will need to spend some extra dough to calibrate my speedo w/a mega short? Drivetrain and gears are stock, but I've got the 33's...

who's mega short are you using?

either way, i'm pretty sure all of the "short" SYE's use a tone ring (like found in rubicons) instead of a gear. the spedo signal will transmit to the speedometer guage, but will be off (IIRC back to stock spec).

you would need the speed-o-healer to correct the signal. (there are other options, but the speed-o-healer seems to be the most popular with jeep guys.) so its not something that would have to happen right away. but to do it right you would want to.

the nice thing about the speed-o-healer is you can adjust it (on the fly i believe) easily down the line when you go with bigger tires and/ or re-gear. so no need to buy new spedo gears anymore.

i looked into all of this recently, but decided that a regular SYE would suit my needs b/c I dont plan on swapping out my 2.5OME lift for anything taller.

again, there are advantages to the "short" SYEs. with 4" of lift and a TT you will most likely want one. so set yourself up properly from the get go and save your pennies for another month or two.

so you probably dont need one with your current set up, but down the line....

I don't have one yet. But I've been looking at Rugged Ridge's Mega Short. But the more research I do, the more expensive this is becoming. Mega Short SYE, CV DS, Adjustable Arms, Speed-O-Healer, then maybe a tummy tuck while I'm at it. $F*CK.00

Might be back to the drawing board. Oh and what part of Maryland? I was born and raised NW Baltimore County.

I have verified my speedo with GPS several times and its within 2%.

JB should add that information to their product description. They should just list the tire sizes and gear ratios that its calibrated for.

doing a jeep correctly is NOT cheap. As I'm learning.

St Mary's county. Southern Maryland. Just over the bridge from Solomon's island
