Body lifts are only good for ground clearance from bigger tires. If you jump the truck at all, even speed bumps, you will need to buy two kits, as the Tacoma kits come with narrow blocks, which WILL punch through the mounts on the cab, which is very expensive to repair. The second kit should be purchased for an older truck, say, 74 Blazer, so you get the wider spacers. However, unless you are dead set on a body lift, do not waste the time, money and effort, as it will not handle right, will cause you to retighten the mounts every hard trip, and causes radiator/clutch fan/engine clearance issues when it flex's.
