I was just looking at my rear sway bar as I had decided that it would be better if I lowered the mounts to match the increase in height with the new longer springs, "clear as mud" Just want to bring it all back in proportion as it was prior to lifting the rear. I have a dilemma however as the sway bar on level ground has no tension and if I were to lengthen the mounts this would put the system under tension is this correct or should there be no tension while the wheels are all on level ground. Who can help please?

Hi Walter,

A sway bar is designed to have no tension if both sides are even. The only time it is under tension is when it is twisted by one side of the car being at a different level to the other. This is most commonly caused by the car leaning when going round a corner and therefore the sway bar tends to help reduce the lean. It also tends to reduce the travel of the wheels when one wheel drops or raises during 4wd activities so some people take them off if they do a lot of that. Not recommended if you use it mostly on road though.

But back to your original question - Unless the additional height has caused what appears to be a change of the angle that it operates at, say it doesn't seem to move as far as it used to when the suspension moves up and down, then there should be no issues with it at all.

The short answer is Yes, you should lengthen the sway bar connecting rods by the same amount that you lifted the suspension.
If the rod has a threaded end where it goes through the mount just use a connector nut to join a length of threaded rod etc to the original rod. Did my 80 series 9 years ago and haven't touched it since.

Hi Walter

Sways bars do work there best when flat, but unless you have more than a three inch lift the difference is not enough to be of concern. I extended both mine on an 80 series after installing a five inch lift, I did not do it straight away and when I did the difference was amazing. The only down side is the brackets are very exposed.

Have fun
