Poly-Performance 4 link users?

Anyone running this? Looks like this would beat the snot out of the typical LA's. The LA's I have seen unload something terrible. I would like to do this on my MJ and SOA in the rear. I only want to net 4-4.5" lift (to keep it low). I will proabably try explorer rear springs using my 2wd main leaf in the rear for less lift. If I have to I might consider spring sliders to keep the rear around 4".

I'd like to see some installed pics if anyone has some, or likes/dislikes

thanks -J

What do you mean by unload? Hopping on climbs, or excessive tilt on off-camber sections of trail, or...?

major anti-squat. If trying to climb a shear ledge the axle just hangs out while the jeep lifts up not bringing the axle with it. Almost too much flex...

Its not that radius arms give have too much flex. They naturally have less due to the binding they cause compared to a 4 or 3 link. The problem is because the castor changes and there for wants to rotate the axle down and back. This makes the front end light on hill climbs. A 3 or four link keeps castor the same or relatively the same so the front will not have the same affect as if running a radius arm. That poly kit looks nice. The only problems i see are the brackets hanging a little low for a rock rig and I would run a couple bolts through the "frame" on those brackets instead of just the ones that go through the floor.

I think for that much money the Rock Krawler system is a better design.

the RK kit I saw on their site tonight was over $2k ?? The brackets they provide looked cheesy to me compared to the poly ones that act as frame stiffeners too. If I was to install this there is no way I would ever depend on bolts of any kind it would be welded for sure. The RK kit's description mentions the 4 link for high speed and the 3 link for crawling..why would that be? The only thing that looks suspect to me on the poly kit are those adjustment sleeves. I know it may be more convenient to adjust but you really should only have to do it once.
