Air suspension can be a controversial mod, since some enthusiasts love the smooth ride and versatility, while others think slamming a classic car detracts from its original purpose. No matter what your opinion is, a nicely-built classic truck on air bags has a few clear benefits. It's easier to load the bed, easier to level once there's weight over the rear axle, and rides like a dream. This '66 Chevy C10 built by Old Anvil Speed Shop is a great example, and the 500hp LS motor under the hood is just the cherry on top.
