Factory warranty covers Chevrolet's original components, but aftermarket parts and accessories installed after purchase typically aren't covered by the factory warranty. However, genuine Chevrolet parts and dealer-installed accessories can maintain your warranty protection.

If you're thinking about adding accessories-like running boards, tonneau covers, or technology upgrades-talk to our team first. We can recommend genuine Chevrolet parts and professional installation that keeps your warranty intact.

Castle Chevrolet McHenry has a full parts department with genuine OEM Chevrolet parts and authentic accessories. For advice on what to add and how it affects warranty, call (779) 600-2956. We'll help you accessorize your vehicle the right way.
