I've had a 2 inch leveling kit on my '14 Sierra for about two years. It's made by MotoFab and made of billet aluminum and then anodized black. I wasn't even aware of the different types of control arms at the time but recently came to learn mine are steel. I've seen a few posts lately that have mentioned galvanic corrosion. Looking at my suspension now, it still looks really clean. Is this something that I should worry about in the future? I'm also curious about ride quality with my billet aluminum spacer versus the hardened nylon you would get with Rough Country. Any input would be much appreciated!

Hey guys, I'm looking at buying a 2" lower mount spacer off ebay for around $30. From what I've read and heard, they are the easiest and quickest install. My local dealership wants 250 for install and an alignment. That seemed a little steep to me so I checked with a custom off road shop in the area and they wanted about the same. Should I shop around a bit or are these prices pretty normal?

Congrats! Enjoy the new whip!
