Hey, I'm bolting on my rancho prerunner 2-1/2" front springs on my FI '79 sm465/np205 Blazer and it has been advised to me to run the stiffest shocks I can find. II'll probly need to reinstall the quad shack setup. Let me know what you all think, I'm open to suggestions. Brand, to quad or not to quad, whatever you can think of. I drive this on the hiway too. Warn XT's? I can get them cheap on line. THANKS Bouncy in the upstate mountains of NY.
