Chevrolet has long used the designations “LT” and “LS” for identifying features in their cars and trucks. Beginning in the 1960s, they used both prefixes to identify engine models such as the LS-6 and LT-1 performance designation. In the 1970s, they began identifying trim packages in cars; for example “Type LT”.
Currently, the monikers “LS” and “LT” are most commonly associated with trim levels of the Chevrolet Tahoe SUV. The following trim levels are outlined in order of ascending package features.
