: Dumb coil spring question.

OK guys, need help again. I got the front coil springs cut on the kids 72 Chevelle. First question, can I use a propane torch to heat the end I cut so I can bend it flat like it is on the end I cut off? Second question, should I quench the spring in water after doing this? This is my first time at cutting coil springs, so if anybody has done this, I need all the help I can get. THANKS

I'd just leave it as it is.

Contrary to popular belief, there's nothing wrong with heating up the springs. As long as you let it cool slowly, it will not have any real effect on the spring's load or rate.

The problem is, however, that chances are you'd end up with a car that leans. Any difference in spring height will be doubled in ride height. It's a lot easier to keep it even by cutting the same ammount off, than it would be to heat and bend it exactly the same on both sides.

I cut a set of BB coils for my copo one year .I cut the same amount off on both sprigs and let them cool over-nite. The weight of the BB made it squat real nice with no lean.
Hope this helps.......

Thanks guys, I will just leave them the way they are, and move on to the rear springs.

...and move on to the rear springs.Just cut off the upper pigtail... took me 3 sets of used springs to figure out how much it actually drops with just the pigtail cut off.... glad I had spares laying around :eek: It easily dropped over an inch with just the pigtail cut off.

How much does cutting the springs in thr front or back affect the ride quality? Does cutting the pigtails off make the ride much worse?

A buddy of mine bends some of his wrench's with a torch then uses quaker synthetic oil to pour on it, He says it helps keep the strength.. Not sure if that means much just thought like sharing:clonk: But then again i think he's a X-tweeker

You should always cut the end of the spring that isn't flattened.Its alot easier that way.
If you use a cutoff wheel on a grinder the heat is localized and easily quenched with a soaking wet rag.If you're really worried about heat you can fill a 5 gal bucket with water and put the spring in there while you're cutting it.
