your front should have coil springs don,t cut or heat them it better to bye the the spring with the link taken out mine is droped 4inches but thats too much I have to rase it a inch my headers hit speed bumps that just requires me to get huger headers but you also need to concider where your oli pan is at you get it to low ! well you know what will happen to me if had to do it all over again I would get a air bag kit it should have every thing ya need for front and back .I should of ask frist do you have a strate axle in front or A-arm supention in front i there is another way but that requires cutting up your truck and putting a camaro sub frame in front
