ive had my truck for about three yrs and notices a while ago that it has coilovers on it well its about time for new shocks so i took it to my local shop and they told me they could not work on it because it has coilover shocks all the way around with clamps at the bottom of each shock giving it the 2.5" lift i know they make spacers for coilovers but i need to know should i just go with another set of coilovers and lift it with spacers or just do the work my self put regular shocks on the truck? and if i do will i loose my lift i run 31x10.50x15 tires and dont want them to rub i loose the lift.
