Simple Shock question

[Bigbike]

Will XJ shocks work on a YJ?

[Ruecifur]

the mounting points are the same... just check length of compressed/extended to make sure they are right

[Bigbike]

Thanks Dude.

[Magilla]

from what i understand after looking at some part numbers is that the rears are the same but the fronts are different.

[Ruecifur]

its prob the length difference then... again, the mounts are the same, just bust out a tape and finger it out

[XJLI]

lengths are gonna be different, valving is gonna be different.

What about ZJ and TJ? I have been looking around and it seems that skyjacker sells the same shock for TJ, XJ, ZJ.... is everything really the same, or is SkyJacker just half-assing it to make more sales on the same product? I'm asking because I'm looking at some ZJ shocks but am concerned about fitment and length.

skyjacker makes shitty shocks. most shock manufactures bundle XJ/TJ/ZJ front as the same shock (bc the front suspension is the same) and they bundle ZJ/TJ rears (bc the suspension is the same). In reality, universal shocks SUCK. you need a shock valved for your specific application, and travel that fits your setup. will they work across applications? sure. is there a better way to do this? most definitely. but its cheaper to do it the way most manufacturers do.

Some of us can run a longer shock for our lift heights bc we have bigger tires, and thus longer bumpstops. my rear shocks are 8" travel, but are almost 3" longer extended than my rusty's 3" shocks, but theyre too long too allow a 31" tire to tuck all the way up into the fender.

Also-

my bilsteins are 255/70 valve, while bilstein 3" lift shocks for the XJ (the specific ones in the 5100 series) are valved something like 168/48. Great for a comfy ride on road with a cherokee at stock weight.

You need to take in all the extra axle weight (wheels tires, diff covers, steering, if you have D60s or a D30/D44) and factor that in to your shock valving, as well as bumpers, armor and other things when choosing your valving. yeah, my jeep rides a tad "stiff" over roads, but when Im doing 40mph+ over uneven dirt, its super controlled.

So ZJ shocks should do fine in my TJ as long as my lift and tire size will allow then? I firgure the valving isn't that bad since they don't offer a different shock for the 4cyl than the 6cyl.

aren't axles/tires/wheels unsprung weight? why would that effect shock valving?

i was thinking the same exact thing.

just because its unsprung doesnt mean it has no effect on your shocks. its more mass pushing up, and more mass forcing the shock to droop down.

That's what i figured the answer was, but i can't see it having a ton of impact. If you are cruising at 40mph and hit a pothole, the forces going up and down aren't going to be astronomically different between a d60 and a d30.

The only place where you are going to see a ton of compression and extension of shocks is wheeling, and most of the time you are going so slow i don't think it makes a hell of a lot of difference.

So getting a shock valved for a ZJ in my 2.5L TJ should be fine, or no?

[Even]

if fine = will it work then yea it would be fine

But the ride probably won't be anything to brag about. Unless you are getting them for mad cheap then get some valved for a 2.5 tj.
