Looks good n beefy. What kind of joints and what tubing do you plan to use?

alloutperform

1.75 DOM .120 wall with poly bushings

89eliminator

thats some thin tubing...

96_xj

x2. you want 0.25 for your uppers and 0.25 for your lowers minimum. i wouldnt even hesitate one bit to run 0.375 lowers.....

alloutperform

1/8 wall tube is more than enough...to start stock we run on 16 guage stamped steel and if the tubing is good enough for nhra cage and chassis specs in a 9sec. car it's good enough for my jeep..if i bend it i'll make new ones.

96_xj

but there is a difference. in the 9 sec car you probably do not have a span of 32"-35" of ungussetted strait tubing.

it is the length of the tubing that requires the thicker tube. The reason being with that thin wall you nail a rock in the center (and you will) it will bend. I can promise you that now. and I suggest you play safe and run atleast 0.25" minimum.

89eliminator

its not if they bend, they will bend. yeah NHRA may use it but all of there stuff is triangulated and what not. not just one long stick of it.

96_xj

and just to reiterate some more. my short arms are 1.5"x0.25 DOM and i have gouged, slid, banged them up. and they are fine, but if it was 0.120 tubing they would have been bent already. that is with a short arm. the long arm again i would not hesitate to run 0.375 tubing. the cost difference is not that much.

alloutperform

one other really important detail..i don't have rocks..and this is for dd use ride quality and wooded trails if i were to go for rocks i would use thicker tube.

also it's 1 3/4 that was my typo

alloutperform

hey eliminator: off topic do mj's have frames or are they 1/2 unibody never had one and was just wondering i know the beds come off

96_xj

wooded trails even still. i strongly suggest 0.25 or 0.375. you can do what you will, but please stay off the roads if you do use 0.120.

and MJ's are unibody on the cab side then go to frame rails directly after the cab

alloutperform

well i'm not gonna be one of the idiots that don't listen, i'm gonna run to my steel shop see if he has 6ft of 1/4 wall around.. i plan to build the lower arms tonight..


and as far as the MJ that would explain my confusion

89eliminator

yup. its unibody from the cab forward. and the portion that is unibody is stronger than the XJ.

Why stay off roads ?...it would be fine for driving just not bashing . Not advocating it but it would not be a highway safety issue.
