: quick suspension question.

how much side to side movement is acceptable when running a link front suspension with a track bar?

I'm just starting the planning stages of my jeep buildup, and my sketches are showing that my front axle will, when at full drop, shift to the drivers side by about 3"to 4". this is with the axle centered at ride height, and full drop being about 14" lower.

well, since no one replied, I'm going to assume that 3 to 4 inches of side to side movement is ok. now I just have to make up some scale drawings, recheck all my measurements, and start looking for parts.

well...I thought about replying but decided not to:flipoff2:

just off the top of my head I think that there is not a whole lot of concern over it because the whole front axle is very rarely (or never) drooped all the way down. I'm not sure how you could figure out how it would move, laterally, when 1 side or the other is drooped all the way down and the other side fully compressed...not sure if it really matters.
I think you'll do better to spend your time to make sure that the trac bar and drag link are parallel to each other
havn't really researched any of this just tryin to help you brainstorm a little

how are you getting 14 inches of droop? 16 inch shocks with 2" of uptravel?

regardless, 3-4 inches sideways over the course of 14 inches down isn't bad. simply make the panhard as long and flat as space constraints will allow and match the draglink angle (length also would be ideal) to that.

yep, 16" of total travel, probably going to go with air shocks, or posibly something like what "ashman" has on the back of his rig, using 16" travel hydrolic cylinders with air. the 2" of uptravel was just a rough guess, I may end up setting the ride height a little higher than that though, (maybe around 4" uptravel, 12" down travel), which would give me less side to side movement with the axle centered at ride height.

anyway, I'm still working on the plans, and trying to figure out all the details, so there is a chance all this could change depending on what axles, tire size, etc.... that I end up going with.

thanks for the input, it's appreciated.
