Rear YJ Shocks

I have approximately 5 inches of lift. I am wrapping up my swap and wouldn't you know it the shocks that the PO threw on look way wrong. Keep in mind i also installed MORE rear upper shock towers i picked up during their 20% Christmas sale. While the jeep is on fairly level surface, both upper and lower shock mounts are about 20 inches apart. Is it normal for the shock to only have a couple of inches of travel when on the bottom not flexing.

I guess what i am really asking is let me see your Rear shock setups. The shock body on mine seems to long and that there is not enough piston. From the top of the shock body to where the piston starts is 16.5 inches and the piston is about 10.5 inches and the lower shock mount is another inch and a half for a total of 28.5 inches. Does this sound like normal dimensions for a Jeep's shock.

Thanks in advance,
John

The only way to really tell is to take off your shocks and try to flex your rear end like a mofo. Then measure where stuff ends up. From your numbers it sounds like your shocks might be too long. Also, the way you described it makes it sound like you have the shocks mounted body-side up which could be bad for some shocks.

How much of the shiny chrome rod is showing when you are at rest?

DeKalb, huh? My uncle coaches hockey at NIU.

~2" sounds as if they will bottom out.

This is my passenger rear. MORE uppers, RE lowers. Extended length (not static) = ~26" IIRC.

I mounted the shocks body side down. The shiny chrome rod is only 10.5 inches when the shocks are not on the jeep. When i have the shocks mounted up to the jeep there is only a few inches of the shiny chrome rod, essentially eliminating and more up travel and acting as a premature bump stop. The body of the shocks are 16.5 inches. I think that not only are they to big but also are for a different application.

Well, you don't want the shock to be a bump stop. Where is you lower mount? I would do the same as post#2. You need to know your travel... distance from fully stuffed to fully drooped. I don't have a pic handy, but mine looks like Joes (except I do'nt have those nice shiney Fox's. lol.)
It's all relative. The mounts, upper and lower, need to match the length of the shock, including the length of the can, the travel, ect. You may have to adjust your lower mount to match the MORE upper. That would be my guess.

I am going to go out and measure them and i will get back to you. My setup is almost a mirror to that of Joe Dillards except for stock springs.
