Key Takeaways:
- The Law Protects You: The Magnuson-Moss Warranty Act prevents dealers from voiding your warranty for aftermarket parts alone.
- Burden Of Proof: A dealer must prove the aftermarket part caused the failure before denying any warranty claim.
- Our Warranty Stands: Every Pacbrake air spring and bracket carries its own lifetime warranty regardless of dealer claims.
Short answer is: no, air bags do not automatically void your truck warranty. That is the direct answer most dealers will not give you upfront when you ask about aftermarket suspension. Federal law governs exactly what a dealer can and cannot void when you install an aftermarket part. The burden of proof sits with them, not with you.
In this piece, we’re breaking down everything you should know about whether air bags void your warranty, what your dealer can and cannot do, and how our warranty protects you independently on top of your factory coverage.
What The Law Actually Says
Most truck owners have never heard of the Magnuson-Moss Warranty Act, but it is this federal law that determines exactly what a dealer can and cannot void on your truck in the United States. Canada does not have a federal equivalent to the U.S. Magnuson-Moss Warranty Act, because consumer protection and warranty regulations are handled at the provincial level rather than nationally.
The Magnuson-Moss Act Explained
The Magnuson-Moss Warranty Act is a United States federal law that prohibits manufacturers and dealers from voiding an entire vehicle warranty simply because an aftermarket part was installed. The law requires that the warranty provider demonstrate a direct link between the aftermarket part and the specific failure being claimed before any denial is legally justified.
The Federal Trade Commission, the only federal agency that handles both consumer protection and competition issues across broad sectors of the economy, enforces the Magnuson-Moss Act and has issued Consumer Alerts confirming that the law makes it illegal for companies to void a warranty or deny coverage simply because an aftermarket part was used, and that a dealer must demonstrate the aftermarket part caused the specific failure before any denial is justified.
Burden Of Proof Is Theirs
A dealer cannot look at your air bags and declare your entire warranty void on the spot. They must prove that your specific aftermarket suspension component directly caused the failure they are refusing to cover. Without that proof, the denial does not hold up under the law. Knowing this before you walk into a dealership changes the conversation entirely in your favor.
What Can Still Be Denied
The law does not give aftermarket parts unlimited protection. If your air bag kit directly causes a failure in a related factory component, the dealer can legally deny coverage for that specific repair. For example, if an improperly installed kit damages a factory leaf spring component, that targeted denial is valid. The key word is specific. They cannot use one component concern to void unrelated systems across the truck.
Air Bag Suspension Warranty Coverage
Our air suspension kits carry their own independent lifetime warranty on every air spring and bracket. That coverage exists regardless of what your factory warranty does or does not cover. If a dealer denies a factory claim related to your air bags, our warranty still protects the kit itself. You are not left without coverage on either side of the install.

What Dealers Say vs What The Rules Allow
The gap between what some dealers claim and what they are legally permitted to do is wider than most truck owners realize before they run into it.
Common Dealer Claims
The most common dealer claim is that any modification voids your entire warranty. That statement is not legally accurate under the Magnuson-Moss Act. Dealers sometimes make it because many truck owners accept it without question.
The Specialty Equipment Market Association, the membership-based nonprofit dedicated to the success of the automotive aftermarket industry, identifies protecting consumer warranty rights under the Magnuson-Moss Act as a top legislative priority and has formally called on the FTC to require dealers to provide written explanations when they deny warranty coverage for aftermarket parts. Understanding the law before your next service appointment means you are prepared to push back with facts rather than frustration.
How To Respond At The Dealer
If a dealer denies a warranty claim and cites your airbags as the reason, ask for the denial in writing. Then ask them to provide documentation showing how the air suspension kit directly caused the specific failure they are refusing to cover. Most dealers will not have that documentation because, in most cases, no such link exists between a properly installed air bag kit and unrelated drivetrain or engine failures.
Air Suspension Installation Standards
How your kit is installed matters for your warranty position. A proper air suspension installation that follows the manufacturer's guide and uses all included hardware gives you a defensible position if a claim is ever disputed. Our kits ship with comprehensive installation guides for exactly this reason. A clean install documented with photos and a saved purchase receipt puts you in the strongest possible position at the dealer counter.
Keeping Your Documentation
Save your purchase receipt, installation guide, and installation photos. Once your kit is installed, complete your warranty registration to activate your lifetime coverage and officially timestamp your installation date.
The Auto Care Association, the voice of the $516-billion-plus automotive aftermarket industry representing the entire supply chain from manufacturers to repair shops, specifically advises consumers to record all maintenance and repairs, save clearly dated receipts describing parts and services, and note that the manufacturer or dealer, not the consumer, bears the burden of demonstrating that an aftermarket part caused any specific failure. Store all documentation somewhere accessible so you are not scrambling if a claim comes up later. Documentation costs nothing to maintain and is your first line of defense against an unsupported denial.
Steps To Protect Yourself Before And After Installation
A clean paper trail before and after air suspension installation is the best protection against any dealer pushback on a future warranty claim.
Your Checklist
- Read Your Factory Warranty: Know what your OEM warranty covers before installing any aftermarket suspension component on your truck.
- Keep All Receipts: Purchase records, installation guides, and kit documentation back up your position firmly at the dealer.
- Register Your Kit: Register your Pacbrake kit to activate your lifetime coverage and officially timestamp your installation date.
- Get Denials In Writing: If a dealer refuses a claim, request written documentation of their stated reason before accepting it.
Being informed and organized before a warranty dispute arises is the difference between a resolved claim and an unnecessary out-of-pocket repair on a system that was never the problem.
