How likely is it that the stock front end shaft is the right length? And is there some reference on just how equivalent the two shafts' strengths are? I believe you, but I'm also a skeptic so I love fact checking. I'm looking at a 3"-3.5" lift from DPG and the possibility of needing a SYE. Tough choice waiting to order a SYE kit though as this is my daily driver.

 

Thousands of people use a front shaft in the rear, it's the right length and plenty strong I've seen big hollow shafts like the xj rear twist, I've never seen a twisted front drive shaft, and the power is equally divided in 4x4.

 

Nice! What did the floor boards look like after that let go?

 

Idk, probably not good it was sitting on the counter at my local 4x4 shop, it's not an xj shaft, it's a bigger stronger shaft, just an example of a why the xj rear shaft being bigger doesn't make it stronger than the front.

 

My buddy snapped one two weeks ago, came right through the floor board

 

holy axle batman

 

No problem man
It's the right length because the front is a double cardan shaft, meaning it has no fixed length. The rear shaft is a fixed piece of pipe, while the front is able to slide in and out which is needed, because the front yoke is at a fixed place. The rear has a slip yoke which means the yoke can slide in and out of the transfer case, the SYE makes the yoke a fixed place yoke so the driveshaft needs to be able to extend and contract when the suspension articulates.

I hope that helps.

 

That would suck.

 

I ran across a carbon fiber or fiberglass driveshaft at the JY this weekend. Thought about buying it, just cause it seemed expensive.

+ shocks and a track bar equals over 1000 unless you use jk shocks.

 

Well, then he needs to use RC with AAL's. Lol

 

This is borderline lift question: I swapped in a C8.25 for my D35 but now the parking brake lines are not long enough. Or the housing is not long enough. Are there different length housings?

 

New to liftin my xj ive had it for 6 years now and its over due for some aftermarket my questiom has anyone heard anything good or bad about crown springs saw some oem leaf springs thru jcwhitney for good price want to use them for a start of a rc 2" budget booster kit any advice?

 

Exactly what hennessee said. After shocks and ADSTB itll be over 1k. Not too mention SYE and a front DS from an old xj. Still might do it this way just gonna take a while longer.
