ALCAN Springs and ORD Shackle 4\" Lift? I want to put a 4" lift on my 1991 1-Ton Crew Cab 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?
