. All glider kits include a frame, front axle, and body ( cab). The kit may also contain other optional components. A motor vehicle constructed from a glider kit is titled as a new vehicle in the United States. An exception to this is the state of Georgia where, when issued, for a tractor cab restored with a glider kit will always be branded "Rebuilt".

Glider truck

A glider truck is manufactured in the United States using a new frame from an original equipment manufacturer and a glider kit. A "pre-emissions" engine which does not meet current EPA emissions standards for a new tractor trailer may be installed. The required

(EGR) technology is replaced by an older engine which doesn't have it, called a "pre-EGR engine." Production of heavy duty glider trucks was estimated to be 10,000 in 2015, 4% of all sales. An Obama-era limit on production of 300 units yearly was lifted by the Trump administration. This change by the EPA was widely condemned by environmental groups and was withdrawn by Scott Pruitt's interim replacement facing the prospect of a likely loss in court.
