The GMT900 (2007–2013) Silverado/Sierra dash can develop hairline cracks over time, particularly in hot climates. Here are the best options for fixing it.
GMT900 Dash Design
The GMT900 uses a soft-touch panel above the cluster and a harder panel on the lower dash. The soft-touch area is most prone to cracking from heat cycling, particularly around the passenger airbag seam.
Option 1: Coverlay Dash Overlay
A Coverlay molded dash overlay is a pre-formed cover that snaps over the existing dash. Available in black and factory colors for GMT900 models.
Pros: No disassembly required, quick fix, covers all cracks permanently
Cons: Changes the dash profile slightly, may affect HVAC vent flow
Cost: $120–180.
Option 2: Full Dash Replacement
A complete factory-style replacement dash from Dorman or aftermarket suppliers restores the original look. This requires removing the entire instrument cluster, HVAC system connections, and often the airbag module.
Cost: $300–600 parts, plus 6–8 hours labor.
Option 3: Vinyl Repair
For hairline cracks only, vinyl repair kits can cosmetically fix the damage without replacement.
Practical Interior Upgrades:
While the dash is apart, good time to:
- Upgrade to the Tuffy Console Safe in the floor console
- Install Husky Liners Weatherbeater floor mats
- Check instrument cluster for dimming pixels (common GMT900 issue)
