Powder coating coil springs.

[87GNSteve]

I've heard horror stories of guys changing the front coils, to have lopsided cars or jacked way high. I took mine off and had them sand blasted, they had a nice ride and only had surface rust and cleaned up real nice..
My thought was to get them powder coated, but had 2nd thoughts to the high temp during the process affecting the spring/metal. Please advise.....

If the temperature is too high you will soften the springs. I would talk to your powder coater and find out what the temp would be and for how long.

The temp would be 375 for at least 20 min

I painted mine with VHT satin black # 322-SP739 from Jegs,it's made for brake rotor and drums it resist chipping, cracking or fading and good for temps up to 900 degrees. It works very well and is only $9 a can ,you will need 1 1/2- 2 cans per spring with 3 good coats applied. I know it's not powder coat but I did mine 4 years ago and they still looks like they where just done. I also did my front knuckles, dust shield, calipers, drums, front lower control arms, J bracket for turbo shield, drive shaft, rear end and they are all holding up very well. Hope this helps.

The temp of coating will NOT affect the spring properties in the steel at all. The temp is 350-400 max I do believe. I had the front springs in my 62 coated in 1998 and it sits the same 14 years later. They support a cast iron 409 and 6-71 blower. Thats way heavier then our dinky little 6's. 350 to 400 is frozen pizza temp, not steel affecting temp. I really like the spray on rubber coatings from Eastwood, if your searching for other avenues.

Sounds like an interesting car. Bring that on Sunday instead!

My baby. I got it from my dad as a high school grad present in 1988.

I did my Eibach springs, done with no problems. They get cooked at 400 degrees for 30 minutes at the powder coaters.
