2021 GMC Terrain Accessories & Parts

The GMC Terrain is conceived as a more premium alternative to its mechanical twin, the Chevy Equinox. Both face fierce competition from well-established models on the compact crossover SUV market, including the Honda CR-V and Mazda CX-5. The Terrain was fully redesigned for 2018 and continues receiving yearly improvements to be able to survive in a tough segment. This year, GMC intends to increase its appeal to active families by giving it the off-road-focused AT4 treatment. Not only does the package offer all-wheel capability, meatier tires, and suspension upgrades, it also gives the SUV a bolder look with a tweaked grille, bigger headlights, and unique wheel designs, while adding accessories like specific badges and body cladding. For further upgrades to whatever version you own, choose from our wide array of 2021 GMC Terrain accessories and parts.

Both turbo 4-cylinder gasoline engines carry over for 2021, with the base 1.5-liter unit putting out 170 hp and 203 lb-ft of torque, and the available 2.0-liter powerplant capable of 252 hp and 260 lb-ft of torque. Regardless of the engine option, a 9-speed automatic transmission takes care of power delivery to either the front or all four wheels. With the optional engine under the hood and proper equipment, the Terrain has a tow rating of up to 3,500 lbs. On the upside, the Terrain delivers on ride comfort. Active noise cancellation is standard across the board. The suspension setup of all trim levels provides a smooth and controlled ride, while making the SUV nimble around town. The top-tier Denali, however, takes ride quality to the next level with a premium suspension and hushed cabin.

Sleek exterior design is what gives the GMC Terrain a few points over the competition. The interior is comfortable and nice-looking as well, and with a wide variety of 2021 GMC Terrain parts and accessories available, there are plenty of ways to make it even more pleasant to be in. The cabin doesn't disappoint from a practicality standpoint. The rear seats lay down and the front passenger seat can be folded flat too, revealing generous space for cargo. If only small items need to be transported, there are 29.6 cubes of trunk space. On the safety front, the Terrain delivers like any modern family SUV should, with excellent crash test ratings and plentiful electronic driver assist features. Automatic braking in an emergency situation, forward collision warning at low speeds, active lane control, and blind spot monitoring all come standard on even the least expensive Terrain.
