Symptoms to look for

Height is the usual reason, particularly on lifted or heavy duty trucks. On a heavy duty pickup, trim, tow package and drivetrain each move part numbers within one model year.

The case for genuine GM

• Ships from Dallas. Running Boards and Steps ordered by 3pm Central go out the same business day.
• Straightforward returns. No restocking games on running boards and steps that did not fit.
• GM stands behind it. The running boards and steps warranty comes from the manufacturer, not from us.

Ordering correctly

When a component is superseded, GM documents why. That history is worth having when something failed early. Two vehicles off the same line in the same week can take different parts. The VIN is how we tell. Most orders leave the same day. Oversized and freight items take an extra day to crate.
