Is sye and cv stronger than stock?

[ddodd10]

I know sye and cv help with pinion angle and more importantly vibration. I have soa rear and 6.5 coils front with no vibrations. Would it benefit me to sye and cv driveshaft or should I just leave the stock fixed yoke and driveshaft.

The HD SYE kits are stronger than stock. 32 spline output vs a 27. Most of the driveshafts you would have built are stronger than stock, especially if you go with a Tom woods or JE Reel or that 1tonCV guy (forget his company name).

 

Do you need the strength? Depends on how hard you are on it.

Not sure if you have a SWB or LWB MJ, but I just did a SOA swap on my LWB MJ and I'm still able to use my SY-style rear drive shaft with no vibes.
