ALCAN Springs and ORD Shackle 4\" Lift? I want to put a 4" lift on my 1991 1-Ton Crew Cab 4X4 P/U, which I plan to use for light trail wheeling and occasional towing. I was thinking of going with ORD Shackle Flip-Kit, ORD front greasable shackles (if they make them for my application), custom manufactured ALCAN springs front (4" Lift) and rear (OEM), with overload springs on the rear. My question is: 1. Are springs from ALCAN a better quality choice over BDS Springs? 2. What are some of the experiences anybody has had buying springs from ALCAN? 3. For towing should I go with overload or an add-A-leaf spring for occasional towing? One of the problems are that I need a set of new OEM leaf springs for the rear, and I cannot find anybody that carries any. I checked places like NAPA and AutoZone, but they do not seem to carry leaf springs. Chevy dealers have them, but they cost more than a set of custom springs from ALCAN. Custom springs seem to only average about $50 to $60 more than off the shelf, and custom springs are a matched set, if that claim actually means anything.
