A modification package designed to reduce the overall width of a vehicle’s rear axle assembly. These kits often involve shortening the axle housing, axles themselves, and potentially modifying brake components to achieve a narrower track width. As an example, a hot rod builder may employ this to accommodate wider rear tires within the confines of the vehicle’s body.
The primary advantage of this type of modification lies in improved aesthetics or enhanced performance capabilities. Historically, it has been utilized in drag racing and custom car builds to achieve a specific stance or to allow for the fitment of larger tires that would otherwise not be possible. This customization can provide improved traction and a more aggressive visual appearance.
