That locks in your vehicle so every part we show fits. Genuine GM parts at up to 40% off dealer prices.
If you are keeping a full-size SUV on the road, the fastest way to get the right part the first time is to start from the exact model year. GMT900 through 2014, K2XX from 2015 to 2020, and the T1XX with independent rear suspension from 2021.
2018 is a carryover year for this vehicle. That makes sourcing simpler in the mechanical systems and no simpler at all in trim and body. Second and third row seat configuration, rear HVAC and towing package all change part numbers on these SUVs.
The parts we ship most for the 2018 Chevrolet Suburban are rear load leveling parts, brake rotors and pads, control arms and bushings, window regulators and liftgate struts and hardware. Everything on this page is a factory GM part, built to the original specification and carrying the original part number. On a full-size SUV these are the components that carry load and heat, and they are where an aftermarket substitute costs you the job twice.
Body and exterior parts are where fitment errors get expensive, because a panel that is close but not correct will not line up with the panels around it. Confirm those against the VIN before ordering rather than after.
If you are not certain which version you have, give us the VIN and we will confirm fitment before you check out. In stock orders placed by 2pm Central typically leave our Dallas warehouse the same day, so most of the country sees short transit times. If you are servicing more than one vehicle from that year, our 2018 Chevrolet catalog covers the rest of the lineup.
We specialize in GM vehicles that are 10 to 15 years old, and we often carry new-in-box parts for older models too. Discontinued parts are a normal part of the OEM business. When GM stops making a part and our stock is gone, that is the end of the line for that OEM part. We thank you in advance for understanding. The GM Parts Club advantage: our massive buying power lets us stock deep on the parts GM owners need, in our huge warehouse in Dallas, Texas.
