OEM-spec windshield replacement in San Antonio. The same factory glass thickness, tint, sensor cutouts, and antenna spec your manufacturer originally installed. AGSC-certified techs, ADAS calibration in-house, lifetime workmanship warranty.
“OEM” stands for Original Equipment Manufacturer. In auto glass, that’s the glass that came on your vehicle from the factory — produced under contract for the automaker, branded with the manufacturer’s logo, and meeting the exact specifications they engineered for: thickness, tint, UV coating, acoustic damping, antenna integration, sensor cutouts.
“OEM-equivalent” or “OEM-spec” glass is produced by the same major manufacturers (Pilkington, Saint-Gobain Sekurit, AGC, Fuyao) to the same specifications, but without the automaker branding. It’s structurally identical, meets the same DOT standards, and is what insurers approve for most claims.
“Aftermarket” glass is produced by other manufacturers to general industry standards. It works, it meets DOT requirements, and it’s cheaper — but it may not match exactly on tint, antenna position, sensor cutouts, or acoustic properties.
For a 2010 sedan with no special features, the difference between OEM-spec and aftermarket is mostly cosmetic. For a 2022 SUV with a forward-facing camera, lane-keep assist, automatic emergency braking, heads-up display, and acoustic damping film — the difference is whether your safety systems work correctly after the install.
OEM-spec glass is engineered for:
We default to OEM-quality glass on every windshield replacement. That means the glass that goes on your vehicle either is OEM-branded or is OEM-equivalent from a top-tier manufacturer producing to the same factory specifications. We don’t quote you OEM and install aftermarket — that’s a tactic some shops use to win the quote and undercut the install.
If you want OEM-branded glass specifically (the manufacturer logo on the windshield), we can source it — usually at higher cost and with a longer lead time as it’s shipped through the dealer parts network. Most insurance carriers approve OEM-equivalent and may charge an upgrade fee for OEM-branded.
Most Texas auto insurance policies cover OEM-equivalent glass at no additional cost under comprehensive coverage. Many Texas policies include zero-deductible glass coverage, which means a lot of our customers pay nothing for the install.
If you specifically want OEM-branded glass, your insurer may cover it (some do, especially for newer luxury vehicles), apply an upgrade fee, or require you to pay the difference. We verify with your carrier before ordering.

Yes. OEM-spec glass has the camera bracket mounted to factory tolerances, which is what makes ADAS calibration work cleanly. Some aftermarket glass has bracket position variations that can complicate or fail calibration. We do ADAS calibration in-house on the same day as the install.
OEM-equivalent glass is usually in stock or available same-day from a regional supplier — same as aftermarket. OEM-branded glass shipped through the dealer parts network typically takes 1–3 business days.
OEM-branded glass has the automaker’s logo etched in the corner. OEM-equivalent glass has the manufacturer’s logo (Pilkington, AGC, etc.) but not the automaker brand. Both are fine for insurance and DOT compliance.
Same-day install. ADAS calibration in-house. All insurance accepted. Lifetime workmanship warranty.
