I have a 2003 crew cab Sonoma ZR5, bought it new and lately been thinking of a new look for it. Would love to get a lift but keep running into kits that seem to always say "won't work on the zr5 model"..... Why is this and could I please get some advice on how to lift this truck...... I've seen some cool pics that look awesome, maybe 4 inches or so with big tires. Thanks
