Front wiper blades: driver side 22 inches; passenger side 22 inches; rear wiper blade (if present) about 12 inches. This article explains the typical sizes and how to verify them for your exact configuration.
Understanding the model and configuration
The 2002 Silverado 2500HD came in Regular, Extended, and Crew cab configurations, and some trims included a rear-window wiper. Because blade lengths can vary by cab and whether a rear wiper is installed, the exact sizes may differ slightly from one vehicle to another. Always verify before purchase by checking the current blade lengths, your owner's manual, or the GM parts cross-reference for your specific truck.
Front wiper blade sizes
Before listing the sizes, note that replacement blades are usually matched in length for the two front positions. The lengths below reflect common factory fitments for this model.
- Driver-side front blade: 22 inches
- Passenger-side front blade: 22 inches
Most front wiper replacements for this model use a 22-inch blade on both sides. If your passenger blade is a different length, double-check your cab configuration or current blade part number.
Rear wiper blade size (if equipped)
Not all 2002 Silverado 2500HD versions include a rear wiper. If yours does, the rear blade is typically shorter than the front blades.
- Rear window blade: 12 inches
If your truck does not have a rear wiper, you can disregard this size.
Summary: Front wipers are typically 22 inches on both sides; rear wiper, when present, is about 12 inches. Always confirm with your exact cab configuration or OEM references to ensure a perfect fit.
