I had Superlift and rode very harsh. I have OME now and I removed one leaf from each spring and it rides and flexes great. I always heard that skyjacker has a good ride although I have never tried them personally.

 

what part of CO are you in id be willing to lend a hand

 

Oh for your heatcore try this you! I did it last night to my truck and buddys truck last night.. With your inlet and outlet hose run compressed air into your outlet hose and have a bucket for or jug for you inlet hose it will push all the gunk out. Then run water hose through it to clean it more then redo step #1. Worked for me and buddy!

 

If you are goin to change the springs and such, don't Rough Country, your but is going to thank you, it rides as its name, rough...

Rebuild engine and do rears up front and 63" chevys in rear, you will get more suspension flex and close to same stock suspension feel.

just my 2 cents...
