trailing arms

So I currently have rose jointed trailing arms but these are now knocking which seems quite common, so Im looking perhaps to change to johnny joints. Just wondered what others are running and some advice on whats best to run with 3" sus lift and 2" body lift.

Cranked arms with polybushes from the likes of Super-Pro who use a special grease to let the centre turn inside the bush without wearing them out pronto.

I believe Terrafirma do a johnny joint for about £60 but that's quite steep considering yo needs 2 of em

I currently have QT trailing arms, but they are no more. So Im not sure if a johnny joint would fit on these arms. I may have to get some new trailing arms and johnny joints

How thick are the walls of the QT arms?

Could they take a tap out for the JJs? Or maybe even have a nut welded on for them?

Less lift??

Seriously though. Are you getting enough travel that the stock bushes are being restrictive? Not saying you aren’t. But the stock A arm/4 link actually flexes pretty well all things considered. Longer shocks will give more travel. But too much and you end up with the springs falling out. I know you can run dislocation setups that look cool when posing. But there is a big question mark on how much extra stability and traction they actually offer. And if you are retaining the stock spring mounts and type. There are limitations to how long a spring you can run too.
