Hi-Risers are a type of highly customized automobile, typically an inexpensive American-built sedan modified by significantly increasing the ground clearance and adding large-diameter wheels with low-profile tires. Depending on the model and style of body, autos customized in this manner can be labeled "donk," "box," or "bubble."
Hi-risers originally grew out of the Dirty South subculture, but the trend has spread across the United States. Vehicles customized in the hi-riser style are distinguished by their oversized (even disproportionate) wheels, ranging from 20 inches to 30 inches or more in diameter (largest being 50 inch), as well as fanciful custom paint-jobs and expensive audio equipment. Suspension modifications similar to those employed on lifted pickup trucks are made to give adequate clearance for the large wheels. Often the suspension is modified so the front end sits slightly higher than the rear end, giving the car a swaggering appearance. Because of the exaggerated look gained from installing a lifted suspension and enormous wheels, donks are also known as "hi-risers" or "sky-scrapers."
The most popular vehicles for these types of modifications are full-size Chevrolet models, namely the Impala, and Caprice, as well as mid-sized models such as the Monte Carlo, and Chevelle. However, similar fullsize Ford models (Crown Victoria, Lincoln Town Car, Mercury Grand Marquis) are also popular, largely due to the ability to cheaply buy former police service Crown Victorias. There are three main sub-types of hi-riser, although the distinctions are blurred and open to debate. Most hi-riser enthusiasts agree that a "donk" traditionally is a 1971 to 1976 Impala. They were given this name because the "Impala" symbol was referred to as a "donkey" by owners or "donk" for short. To complement the sloping rear, the suspension of donks are frequently higher in the front end than the rear, resulting in a nose-up stance. Other hi-risers are usually raised evenly, resulting in a more or less level stance. A box is another sub-type of hi-riser, usually a 1977-1990-era Impala or Caprice with a boxy or squared-off front and rear end. Other models that are frequently made into hi-risers include the G-body Buick Regal, Oldsmobile Cutlass, Chevrolet El Camino, Pontiac Grand Prix, and Pontiac Bonneville.
Other vehicles gaining in popularity as hi-risers are the Cadillac DeVille and Seville, as well as the Buick Roadmaster. Also gaining in popularity are the Ford Crown Victoria, Mercury Grand Marquis, and Lincoln Town Car sedans. These three are the last full sized, body-on-frame, RWD sedans of which the Lincoln Town Car is the only one still being sold for 2011. In fact, the Grand Marquis in particular is enjoying a slight sales surge due to the increasing popularity of buying them new and turning them into hi-risers. Several rappers have alluded to the Grand Marquis in their music, such as Dorrough's "Ice Cream Paint Job": "Grand Marquis, paint job grape jelly."
