Leaf Springs,Replace or recondition?

I agree a hundred bajillion times about the American made springs. I don't know about your steel assessment, though. Think about this. Springs are made from spring steel. It's already been tempered. You're talking about rearching and tempering worn spring steel. Notice I did not say retempering. Because steel that has been tempered, does not lose the hardness, it only loses strength through fatigue and that cannot be restored through a second tempering. Tempering hardend steel even more and makes a fatigued spring even more brittle, IMO. I think the only way to acheive what you're really talking about there is to melt down the steel and start all over.....but I could be wrong.


If rearching is done properly and they are retempered I think rearched springs are better than new.Consider a lot of springs today are from Mexico and China. I myself would rather have good old american steel. Mopar Performance springs are mexican junk nowadays. If you do opt for new springs check out Espo.
