I know this is not the prefered way to do things, and I am not doing it...however, a friend of mine is wanting to do it and we need to know whats the bast way of going about it.
Do we heat the entire spring. or can we do 2 or 3 coils since we only want a few inches. Once we have the desired height, do we quench them, or let them cool on there own? |

do not throw em in water they will break in short order. they become extremely stong and hard but yet they are brittle. i do not know the correct way to heat which by the way as it seems you already know there is no correct way bad bad idea but its not your life its your buddies. to me its worth the 200 bucks or whatever its going to cost to get new springs just for the safety factor

his front suspension is gonna become "really" bouncy, because he will be loosing his "spring rate" by heating them,he will probably end up with a front end that sits crooked,because you cant control the amount of heat in the same spot on both springs.(counting out loud wont work),if you throw cold water on the "hot" springs, you will harden them and they will become very brittle,,,,, heat the same coil on both sides to minimize sag,"DONT" use the middle coils ,it will cause the front end to drop real fast,,,,,i really dont think he is gonna end up a very happy camper after this,,,but who knows you guys might get them even ...jeff

cut 'em
Find somebody with a plasma wrench and cut them in place. Still not the best, but better than heating them til they collapse. Then get an alignment! good luck, scott

I've done a few of my beaters. I always throw jackstands under the frame horns and heat a 1 coil at a time until it sags to rest on the jackstand and let them air cool.

dont do it if this guy wipes out and the insurance company finds mods like this they may refuse coverage due to the fact that its not a modification made by putting in tested parts and believe me these days they check like the other guy said its not that expensive for lowering springs and a hell of alot safer

If you do the front the truck will not even be drivable, it will bounce up and down with the slightest bump. Before they made lowered spings for these trucks, I have done the rear...just set jackstands to the correct height and heat one coil till it sat down on them and used air shocks to get rid of the bounce....worked ok but I would not do it now since you can get the springs for what the air shocks cost.

I guess I left out the act that is is the rear of the truck he wants to drop. He already chopped a coil out of the front with the plazma cutter.
While I agree that it is not the prefered way, and there is a chance of the spring shattering...I also know of about 25 or so cars and trucks that were done like this back in highschool and none ever had any problems with breakage. Heck, one guy even had a 69 or 70 GMC short/step, and he still loaded it up with rail road ties all the time. Thanks for the info though. |

I suppose the rear is coil. If it is the cheap way put a set of coils out of a early chevelle or elcamino.

No two pieces of metal ever warp the same, why would he think the springs in his truck would. Have him spend the money on the kit and be done w/ it - - - he won't regret it.

I had a friend lower his El camino a few years back, by heating up springs, he heated them up mostly in the middle. It was about 1 pm, he stopped about 5pm, and drove it, looked real cool road ok.
we all went in and bar b Q'd , had some beers, etc, we all left about 9 or 10, next morning it well Cooled the rest of the way and the springs settled out and the E-Camino was sitting flat, univeral and bed was sitting on together and there was about 1 1/2" between the ground and his bumpers. hmm We all learnt NOT to heat them up. Cost more to fix it then it would have just to replace springs with lowered ones in the first place!! i would say Dont do it

If you dont want to spend the $100 on dropped springs, You can buy a kit of compression clamps, they look like U bolts and you put them around a couple of coils and squeeze the coils together. I think Napa sells them in PSE catalog around $20. There made by the same company that make the coils lifts and drop blocks, etc etc
I have a set of new 4" springs I will sell you for $50 plus shipping. Dont ask me what the shipping is, I wouldnt know how to figure it out. I will UPS them to you and you can pay me for them when you receive them. This offer is only for members with a post count of 20000+, PM me if you intrested. |

For how cheap some lowering kits are, just do that. You wont be happy with heating the springs or the kit to press them together, the truck will ride and drive horrible and he'll never be able to put any weight in it ever again.
