Lift Kits & Your RAM Warranty

Does a Lift Kit Void My RAM Warranty? 

At Redwater Dodge, we know that for many RAM owners, the truck leaving the lot is just a canvas. Whether you’re eyeing a six-inch lift to clear 37-inch tires or looking for a more aggressive stance, the most common question we hear in our service bay is: "If I lift my RAM, is my factory warranty gone?"

There is a lot of misinformation floating around off-road forums. Mitch is here at Redwater Dodge to set the record straight so you can customize with confidence.


The Truth About "Voiding" Your Warranty

The short answer is no. Installing a lift kit does not automatically void your entire vehicle warranty. Under the Magnuson-Moss Warranty Act, a manufacturer cannot legally void your whole warranty simply because you used an aftermarket part.

Your engine, transmission, infotainment system, and interior electronics remain covered under the factory terms—provided the lift kit didn't cause them to fail. However, the nuance lies in "causal connection."


Understanding "Causal Connection"

While your radio is safe, the components directly affected by a lift kit are a different story. When you install a six-inch lift and heavy 37-inch tires, you are putting significantly more stress on the vehicle’s geometry.


If the following parts fail prematurely, the repair might not be covered under warranty:

  • Ball Joints and Tie Rods: These are under higher tension due to altered angles.
  • Wheel Bearings: The added weight of oversized tires increases the load.
  • Steering Components: A higher center of gravity and wider stance change how these parts wear.


Essentially, if a failure is caused by the lift or the tire setup, that specific repair is your responsibility. If your AC compressor quits, that's still on RAM.


Mopar vs. Aftermarket: What’s Approved?

Does RAM approve of these modifications? It depends on the height. While RAM offers factory off-road packages and dealer-installed Mopar Lift Kits (usually 2-inch kits), they do not officially approve full six-inch aftermarket lifts.

Mopar kits are engineered to keep everything within factory specs, ensuring your full powertrain and suspension protections remain intact. Once you move into the world of heavy-duty aftermarket lifts, you are stepping outside of factory-tested parameters.


The "Hidden" Costs: Performance and Safety

Beyond the warranty, you need to consider how a lift changes the "soul" of the truck. You aren't just taller; you've changed the physics of the vehicle:

  • Center of Gravity: Your truck will lean more in corners.
  • Braking Distance: Larger, heavier tires require more force (and distance) to stop.
  • Highway Wandering: If the kit isn't aligned perfectly, your RAM will "hunt" across the lane.


The Bottom Line

The lift itself isn't the problem, it's usually a "cheap kit, bad install, or wrong wheel and tire setup" that causes the headache. At Redwater Dodge, we recommend doing it right the first time. Use quality components, ensure professional installation, and understand that you are trading some component longevity for that aggressive off-road look.


Additional Questions & Answers


Q1. Will a lift kit affect my fuel economy?

A1. Yes. Between the increased wind resistance of a higher profile and the rotational mass of larger tires, you can expect a 10-20% drop in MPG depending on the setup.


Q2. Do I need to re-gear my RAM after a 6-inch lift?

A2. If you are running 37-inch tires, re-gearing is highly recommended to maintain your truck's acceleration and towing capacity, and to prevent overworking the transmission.


Q3. Can I still use my RAM’s safety features like Adaptive Cruise Control? 

A3. Most modern lifts require a recalibration of the front-facing sensors and cameras to ensure safety systems like Forward Collision Warning still function correctly at the new height.
