Sierra 2500HD Running Boards & Bed Covers

Before You Buy

Running boards and bed covers are cab- and bed-specific. A board made for a crew cab will not fit an extended cab, and a tonneau cover has to match your bed length to the inch. Check both before you order.

• Wheels and wheel spacers use an 8x180 bolt pattern.
• Torsion keys for 2017-2019 trucks and 2020+ trucks are different parts.
• Turning the torsion bars up firms up the ride. Above about 2 inches, upper control arms are common to keep ball-joint angles in range.
• AT4X and AT4X AEV Edition trucks are usually listed as exceptions.
• Get an alignment after changing torsion key settings.
• Match the cab (2-door/4-door, Double Cab, Crew Cab) and the bed length exactly.
• Running boards hang below the rocker panels and cost some ground clearance on the trail.
• Some covers do not work with bed rail systems, RamBox or multi-function tailgates. The listing says when.
