I thought I would post up my initial review of the Duroflex arms as replacing the stock arms, not a aftermarket one.. I went with a complete set of the double adjustable aluminum. My suspension is stock and I will be swapping axles soon along with a 3" lift, hence the reason for new CAs.
The oem front arms were replaced at 20K ago and in good shape. The rear arms had never been touched and have 110K on them. The lowers were dry rotted and the uppers were as well.
Install was straight forward, there a couple threads that go over drilling the rear upper mounts and that was helpful. I am happy I went with the double adjustable, didn't have to use ratchet straps or a jack. I was surprised how heavy they where and it takes more force than I thought for the duroflex bushing to break free. Both good things IMO.
I can definitely say that after installing the MC arms, the ride is NOT worse than oem. I could tell no difference at low speeds but the jeep did seem more composed at high speeds, going over bumps. I did notice less noise and a somewhat better ride from the rear suspension. So, to summarize, I can say that these bushing provide similar or the same ride characteristics when compared to the oem bushing. I plan to test out the MC arms on some high speed washboard road and rock crawling to see if there are any differences.
