Title: To SYE or not to SYE
Post by: scorpion on June 13, 2012, 08:53:56 pm
For many years, I've been a short wheel base guy.  1972 CST and then more than a couple Jeeps (don't hate, it was a business thing and since then, I have re-found myself).  All that time the theme was to ditch the slip-yolk for a variety of really good reasons.

Now things aren't as much about wheeling.  I have a '74 long bed that I'm in the process of installing a 4L80E.  About a year ago I searched high and low for a NP241 to mate to it and finally found one.  I'm all ready to stuff it in there and my old self is whispering in my new self's ear "get an SYE or you'll be sorry."  My new self replies "it's a truck that I have no intention of ever wheeling, driveshaft angle ain't a problem, space isn't an issue...you don't need one.". Old self is stubborn though.

Details for consideration:  '74 LWB, 454, 4L80E, 14Bolt, 4" lift w/ rear leafs, 35's, and it's not all about the money BUT money is always a factor (save it here, get something else cool instead maybe).

Does anyone have good reasons why it makes sense to keep the Slip-Yolk over a JB-Conversions SYE?

SYE's are fairly spendy aren't they? I've never been huge into wheeling, but I seem to remember some friends complaining about the cost.

If its a street beast, your wallet will prolly thank you for leaving well enough alone.

I think the unit I was looking at is about $400.  They aren't cheap but the up sides sometimes make it worth the investment.

On a wheeling grip I managed to break the rear driveshaft years ago.  Since it wasn't a slip style shaft, I was able to remove it and drive the rest of the trail and back to the trailer in front wheel drive.  Can't do that with a slip yolk t-case (unless you have a yolk that you can stuff in the hole and have figured how to keep it in there while in motion).

Interesting though, not a lot of responses.  I figured there would have been a few good reasons why a SYE isn't a good thing.

If you aren't going off road it is going to be a waste of money in my opinion.

A fixed yoke is great to have.  But if you don't foresee a real need for it, why not spend the money on some other part of the build?

      I have built probably 5 or 6 jeeps that hard core 4 wheeled and several early bronco's.  In a short wheel base vehicle that See's serious off road it is a necessity.  In your truck and what you described for it, as Capt. said, I believe it would be a waste of money, unless you want the bragging rights to say you have one.  8)
