The Quantum Difference

  • Quantum Solenoid is a US based company that employees Americans.
  • Quantum Solenoid conducts QC and inspections of all products.
    • Final product testing, packaging and finishing is done in-house.
  • Quantum Solenoid provides 1 year warranty for manufacturer defects from the date the purchase.
  • Quantum Solenoid can provide faster customer service without the hassle of waiting for overseas responses.
  • Quantum Solenoid conducts R&D and tests products on US and Japan Spec Vehicles to make sure they work correctly and without issues.
    • As car enthusiasts ourselves, we would not sell products that we ourselves would not put in our own vehicles.
    • Having strict and high standards, Quantum is a brand customers can trust.
    • Even if we are using an OEM/ODM factory, a company needs to be responsible and test the products to ensure the customers the peace of mind that the products have been tested for their specific vehicle models here in the US.
    • Other companies may claim that they have tested the units, but if they are overseas, more than likely, they have not correctly tested their products on US or Japan Spec vehicles.
