Your Mods Are A Liability

(And you probably don't even know it)

Insurance companies denied over $2.3 billion in claims last year citing “failure to disclose material modifications.” One undisclosed cold air intake can void your entire policy — not just the engine, everything.

Most car enthusiasts don't know:

  • Which mods require legal disclosure in their state
  • That their warranty protections under MMWA are stronger than they think
  • That disclosing strategically can actually SAVE them money

ModShield fixes this in 60 seconds.
