2021 GMC Sierra Trim Levels

The 2021 Sierra 1500 is available in six trims. These are base, SLE, Elevation, SLT, At4, and Denali. Your choice of GMC Sierra trim will depend a lot on your preferred configuration of cab and cargo bed, since not all trims feature all possible combinations. For example, your only trim option if you want the longest cargo bed with the regular cab is the base trim. The SLE trim adds keyless entry and a larger infotainment screen, among other features.

The Elevation trim offers in-bed lighting, which is sure to prove useful if you work a lot at night or want to move around easier in your cargo box. The SLT trim is a good option if you want a little more luxury in the cab, since it features leather upholstery, heated and power-adjustable front seats, and a heated steering wheel.

In the top-of-the-range Denali, you gain access to all of the Sierra’s driver assistance features, a premium stereo, and wireless device charging.
