The PO dropped my truck by heating the coils and removing the bump stops. I have installed some poly bump stops. There is now about 2" travel before hitting the bump stops. Here is a picture.
I have decided to go with wide tires both front and rear, 295/50/15. They look nice and they clear the bed sides by a hair but clear. The front looks like it's a 4x4. I want the front finder to set nice on the tires but still have clearance for turning. I'm thinking 2 to 3 inches, but I don't really know. Now on thing I did think of was that there is just a I-6 block in the truck now so when it is replaced with the 350, will that lower it any that will be noticeable. I have always heard of heating the springs, but have never seen to done it, nor was I sure how far I could drop the front before camber takes effect needing new spindles. Thanks for the help, nice truck by the way.
Gotcha...well, the spindles will not correct any pre-existing camber issues, but they do offer a predictable amount of lowering. Most dropped spindles locate the pin 2.5 inches higher up on the spindle body, which lowers the vehicle that amount over the stock spindles. If you are looking to modify your existing springs, you can cut a half turn at a time to see how much it will lower your front (spring rate, fatique, etc. play a role in the amount). You will need to shim the upper control arm to get back into alignment spec. Obviously, the best way to lower your front end is to go with a new shorter spring and/or drop spindle, but I understand working with what you got.
