Lowering a truck usually involved cutting coils and shaving bump stops. Out back, the rear end was treated to lowering blocks, a few pulled leaf springs or heated coil springs. Over the years, manufacturers began to address these demands, as lowering coils, spring leaf blocks, dropped spindles and flip kits were offered. Times changed with the introduction of airbags, as owners were able to slam their pickups with full ride height adjustability. Air Ride Technologies (ART) is one of those companies offering quality suspension solutions for truck owners, with kits that fit specific applications.
