Sway bar linkage

The thing is, you have to have some length to the end link in order for it to take up the difference in motion between the LCA as it pivots in a plane perpendicular to the direction of travel, and the sway bar arm, which pivots in a plane parallel to the wheel disk. The rubber bushings are there so that the vertical shaft of the end link can basically wobble this way, then that, at each end independently. But if the shaft is so short that the bushing cups are touching, there is no slack in the system — the ends will bind up and harshly limit the travel of the LCA. To put it another way, the motion of the end link is not straight up and down as a unit — the top travels in an arc, and the bottom travels in an arc perpendicular to the top’s arc.

That's true, and a good reason to get rid of the end link/bushing set up that was on the car previously.

But realistically you're only talking about ~2.5" of travel in each direction, so it's not like you need to have something anywhere near as tall as the factory end links to cover the divergence in the arcs. It’s not that much in that relatively short distance.

This is the set up that I’ve been running for years and tens of thousands of miles, it doesn’t bind up the LCA and those are poly bushings. Obviously you don’t want to interfere with the motion of the LCA, but the more “give” that you have in the bushings and end links the less active your sway bar will be. There are tons of heim jointed sway bar end links out there.
