Catalytic Converter Anti Theft Shield FREQUENTLY ASKED QUESTIONS:


1.) Do the 2007-2021 Tundra Shields protect all 4 CATS?

The shield was designed to cover the front 2 CATs and to cover the pipes all the way to the back CATs to prevent the cutting of the back CATs. The back resonators are visible, but they are still protected by the shield.

2.) Are the shields in the way of getting an oil change?

No. The Shields will not interfere or need removal for an oil change.

3.) Will the shield ever have to be removed for any service?

  • The shield only covers the area of the transmission.
  • Holes are designed in the shield for the technician to do service and drain for the transmission.
  • The shield would only need to be removed if the pan or the transmission needed to have removal.
  • No general removal of the shield for routine maintenance.

4.) Does the hardware come with security bolts?

Yes. All our shields come with security bolts with the bit driver included.
