Specs and Features

• Protects the factory catalytic converter from theft, one of the most stolen vehicle components due to the precious metals inside
• The Tahoe's high ground clearance and exposed undercarriage make it a particularly attractive target for converter thieves
• Secured with patented security screws that require unique included keys, standard tools cannot remove them
• 100% bolt-on installation, no drilling or cutting required
• Designed and engineered specifically for the 5th gen Tahoe's undercarriage layout, not a universal fit
• Made in the USA
• Miller CAT Fitment Guarantee: full refund including return shipping if the shield does not fit a listed vehicle with original converter and no suspension modifications
• Some insurance providers offer a premium discount for vehicles equipped with a catalytic converter protection device, check with your insurer before purchasing

Pairs well with:

• Chevy Tahoe Parts Collection We don't currently have a same-brand Miller CAT companion confirmed for the Tahoe on Redline360, but if you're building out full undercarriage protection for your 5th gen Tahoe, the Chevy Tahoe Parts collection is the place to look for additional protection and accessory options for the same platform.

Converter theft on a Tahoe typically takes under two minutes with an angle grinder, and a replacement OEM converter can run $1,500 or more before labor. The Cat Shield bolts over the factory converter with patented screws that require the unique included keys to remove, meaning standard tools won't work against it. It's not a guarantee against a determined thief with heavy equipment, but it makes the Tahoe a much less attractive and much slower target compared to one without any protection. One thing worth checking before you buy: some auto insurance providers offer a premium discount for vehicles equipped with a catalytic converter shield. It's worth a quick call to your insurer since the discount can offset a meaningful portion of the cost.
