you guys know your chevy's and i need some help... i have an 08 reg cab short box 2 wheeler. i want to lower it 2" more (already have shackles installed) in the rear and 2 up front. i don't want to do a flip kit, i would like to use springs in the rear. mcaughy's said they use the same springs from the 99+ chevy kits. when i talked to beltech they said the older spings ride terrible on the new trucks. are the srings on the ss trucks different from the regular 1/2 tons??? i was told i could use stock springs off of the older trucks because they site lower stock then my 08. i would like the truck to sit like a stock ss silverado, any help would be great!!!
