Workmanship Guarantee & Parts Warranty

Every G&M build comes with two layers of coverage. The first is our Workmanship Guarantee, which backs the labor and installation on everything we touch. The second is the manufacturer warranty on the parts themselves, which varies by brand and product. This page covers both, and explains the role we play in supporting a claim if you ever need to file one.

Most of the parts we install carry their own manufacturer warranty. Coverage varies by brand and product, from one-year limits on certain shock platforms to lifetime structural warranties on heavy-duty steering and suspension components.

If a part fails, G&M Motorsports will help coordinate the claim with the manufacturer when we can. That includes documenting the install, handling the back-and-forth, and shipping the part back when that's the right move. Buying a part online and installing it yourself almost always means you're on your own with the manufacturer when something goes wrong. Buying and installing through us means you have someone in the bay who knows the rep and the process.

The brands and coverage below reflect the most common parts we install. We work with many other suppliers as well; if your part isn't listed here, just ask.

This question comes up in many consultations: will lifting my truck or installing aftermarket parts void my factory warranty? The short answer is no, not automatically. The Magnuson-Moss Warranty Act, a federal consumer protection law, prevents manufacturers from voiding your warranty just because you installed an aftermarket part. They can deny coverage on a specific component if they can prove the modification caused the failure, but they can't void the entire warranty.

In practice: if your transmission fails and you've added a six-inch lift, the dealer can't blame the lift for the transmission unless they can show a real connection. If a dealer denies a claim, you have options. Independent inspection, manufacturer escalation, and in some cases legal recourse.

What this means for our customers: we'll always advise you up front on which modifications are most likely to draw scrutiny at the dealer, document the install cleanly, and back you up if a dealer pushes back unfairly.

If you think a part has failed or our install isn't right, the process is simple:

1. Contact us. Bring the truck in or call ahead. Have your invoice or job reference number ready if you can.
2. Inspection. We diagnose whether the issue is workmanship-related, a part failure, or normal wear. That determines who handles the claim.
3. Resolution. If it's our install, we fix it. If it's a manufacturer claim, we coordinate with the brand to get the part replaced or repaired. Either way, we keep you in the loop.
