Powdercoat or Anodize resi mounts

[Rubberdown]

Hi guys,
So I am about to receive all my shocks and coilovers back from repair/replacment. That being said, I also had to rebuild a few of the reservoir mounts due to rust damage. Should I Powdercoat or anodize the reservoir mounts? I am leary of anodizing because the mounts were previously anodized and the rust damage was extensive, however I know in the wheel wells lots if rocks will hit the brackets and powdercoating is more prone to chip. Gimme your thoughts and opinions!

are they aluminum or steel? I've read that anodizing steel can actually hasten the rusting process, since, effectively, what anodizing actually does is increase the thickness of the oxide layer on the metal. If your metal contains iron, you get iron oxide (rust).
lots of aftermarket bumpers and sliders come powder coated, with no real concerns about chipping

Just a thought here...are you mixing and matching aluminum mounts and steel shock bodies or vice versa? Maybe there might be a bigger underlying issue here like galvanic corrosion? I think a properly anodized surface should stand up to some pretty decent abuse and provide great corrosion resistance.

With that said, I agree with [MENTION=56529]Jon[/MENTION]oful, as a powder coating would probably be more chip resistant since it is a much thicker coating than anodizing I believe. So if your issue is rocks chipping at the protective coating powder coating might be worth a shot!

Well, the mounts are steel, the reservoirs are aluminum, and the clamps are stainless. That's an interesting thought with the galvanic corrosion, although I wonder if I am over thinking it. These things were thoroughly trashed, the aluminum eyelets had to be replaced, shafts replaced, shock bodies replaced etc. Everything that could be damaged due to corrosion was.

lols, maybe you just need to spray down your under carriage a wee bit more often :caked:

Thing with the whole galvanic corrosion deal is, it's gotta be bare metal to metal contact, so I guess you can possible take a closer look next time and see if it's forming where that's going on or if it's just the outer coating breaking down over time.

They didn't come off my truck they were new to me. Let's just say they were not what I thought I was buying. But, whatever. They will never look like that again I can assure you. Everything needed to make them like new was purchased.

The parts that were corroded were where the mount bolts to the frame of the truck and the bracket. I think water or salt or whatever the hell this guy had on it just sat there and ate away.

Powdercoat it is then. Yay more money to spend, but the end is in sight... As far as this goes. I am going to leave the 4runner low for now, I have 6500 miles on the wrangler silent armors so I won't be able to talk the wife into new 285s. In retrospect I should have bought bigger but I wasn't going to do suspension on it. I just can't stand the way the stock sr5 rides.
