Keystone AC1225149 Front Radiator Support Bolt-In Aluminum

The Keystone AC1225149 is a front radiator support assembly designed as a direct-fit, bolt-in replacement for the 2025–2026 Acura MDX equipped with the 3.5L V6 engine. Constructed from lightweight aluminum, this part restores the structural integrity of the vehicle's front end following collision damage.

The radiator support — also referred to as the front bulkhead — is the primary structural frame at the very front of the vehicle. It serves as the central mounting point for the radiator, A/C condenser, cooling fans, headlights, and hood latch mechanism. It also ties the front frame rails together, providing rigidity and ensuring correct alignment of the hood, fenders, and front bumper.

Key Features:

• Bolt-in installation — no drilling or modifications required
• Aluminum construction — lightweight and corrosion-resistant, matching OE material spec
• Direct-fit replacement — same form, fit, and function as the original equipment part
• Restores mounting points for radiator, condenser, cooling fans, headlights, and hood latch
• Meets all applicable federal motor vehicle safety standards
• Engineered specifically for the 3.5L V6 engine variant
