i noticed it in the re bushings thread, i am not so sure if I would move the frame side down, but the axle side up seems like a no brainer

than you could trim that bracket up and box it in

i wouldnt consider it a good idea, for one your messing with the suspension geometry, 2 your making the frame mounted hanger weaker by going closer to the edge of the bracket, your also decreasing seperation of the control arms, putting more stress on the brackets.



Why didnt the owner of this jeep trim up the axle side mounts? that looks silly hanging down like that, but if it were me, i would put it all back to the stock holes.

From how it looks there it seems like the output from the pinion is pointing down quite a bit more.

I could see the increased stress on the frame bracket, but the axle one, your bringing it closer to the "fulcrum" arent you?


and if strength is a concern you could box the bracket, this would be a good idea anyhow since there flimsy


how does less seperation increase stress on brackets?- A serious question because i know little about link seperation other than you want some and it helps with your squat/anti squat

people don't do that for two reasons -
1. you're screwing with suspension arcs
2. you're GREATLY increasing the amount of stress on the mounts.

it is for the nth when using a stinger, not with the upper ca's.

I want your factory 07-up take-off/thrown out JK front/rear Lower Control Arms! Bent ones are perfect also as long as the bushings and cold cut rings are in good shape/useable

Correct. Nth had something like a rear tri-link (and they may have called it a stinger) but relocating the lower arms like this was part of the instructions.

This thread smells of internet scare tactics and rumors already.

I did that with mine as an experiment. Yes it screwed with the geometry... correctly. It reduced the unbelievable amount of antisquat you get with a TJ short arm lift, and put it in line with where a properly setup suspension should be. It litterally made the difference between easily climbing obstacles and nearly flipping over backwards. Also the TJ tire-pick trick (lifting the left front off the ground when accelerating around a corner) is totally gone.

However....

It does stress the mounts and does very little to control wrap. Even with all new bushings and good rod ends, the axle wraps a few degrees. It was a good proof of concept test to see what problems the excessive antisquat was causing, but the tradeoffs are not totally worth it. Now I'm splitting the difference and using the lower hole on the frame end, and the stock hole on the axle end. This helps the geometry a bit without killing the vertical separation of the links.

That's what she said.

hmmm good info


i was thinking of doing it the other way and just raising the axle end and then boxing it in to help alleviate the stess off the mount
