long arm lower, short arm upper

flexj · Jul 15, 2004

Any one ever try this? I currently have Rusty's la kit and am swapping in a hp44. I am toying with the idea of keeping the long lowers and using his uppers in the stock locations. I guess I'll hook it up and flex it with the jack and see what happens.

Also, anyone ever mount their front shocks directly to the lca? Don't the older Broncos do that?

Thanks.

Hamy.

I wouldn't do that if I were you. You'll end up ripping the upper arms off.
But if you do.....good luck!

Are you talking about relocating the mounting point for the lowers, but not the uppers? That won't work. The short arm kit may not work that great for rock crawling, but the geometry is correct. As far as mouning the shocks to the lowers... that's fine. I ran mine like that for a while.

My brother ran a kit with long lowers and short uppers on his TJ for over a year off-road and daily driving, no problems whatsoever. I realize it screws up castor? as the suspension cycles, but is it enough to mess anything up? Anybody running this combo that can chime in? I'm already familiar with the theory behind it, but I'd like to hear from more people who have actually run it, whether or not they've had problems. I'm strongly considering leaving my uppers in the stock location and fabbing up some mid-length lower arms.

A friend of mine did that exact same thing with his cherokee and after a couple of months he snapped the right side upper at the frame mount (tore the mount off the body). The only way I can see the tj not breaking is:
1.) He has a actual frame
2.) He doesn't do any rock crawling

But that's JMO!

think about the link geometry....

wildly differing link lengths will give you wild caster changes throughout the cycle.

If the mounts and hardware were actually strong enough, then maybe it would just stop the axle from drooping, but it would have to be some friggin' strong mounts!

And if the lengths were dramatically different, it's possible that they wouldn't even be able to stay connected to the axle after a certain point in the cycle.

just to stir things up a bit has anyone looked at the full traction TJ longarm kit?? They use longer lowers and shorter uppers. Heres a picture of the kit...

They don't look that much different in the pictures but i have seen it on two different tj's and there is a good difference in length. It seems to work pretty flawlessly but i haven't really seen it other than on a ramp.

Those upperss look longer and dropped to me.

More importantly look at that "foot" long trackbar bracket!

Aw come'on, it's got the cool looking brace going on.
