This part is a not an exact stock replacement part.
First, it's a good quality part with a greasable ball joint. But nowhere, and I mean nowhere, did I see any indication that this, or the 77 for the l/h side, were anything other than stock replacement parts. But according to a MOOG distributor I talked to after noting the difference between these and stock parts, these parts are +2 degree Caster change arms. So Caveat Empetor, do your research first, if you can.

Good Value!
I had the old caster upper control arms on my Chrysler 300. I had it aligned 3 times by 3 different companies and my tires were wearing on the outside edge and the front tires didn't like backing up when I turned the steering wheel more than a little bit. After I installed these, my tires weren't wearing a lot on the outside and I had no more issues backing up with the steering wheel turned more than a little bit. In addition, the steering wheel had a much nicer feel to it, especially on the highway. The ball joints on my arms were grease-able and I didn't see any marking on the part. I've had these parts on the car only a short time, but I'd highly recommend these.

Dang
Front passenger boot lifted of the ball joint after a month after the install. Super disappointing. Next time I buy the non greasable ones. Such a let down

Its a Moog, so it works
These were a perfect fit for my 05 Magnum R/T, and weren't all that hard to install. The worst part was having to drop the front strut to get the bolts to clear the spring. Watch your fingers, folks.

Just what you'd expect from Moog! Great job Amazon carrying Moog products. Fit my Chrysler 300 perfectly, grease fitting included.
