Tundra Cab Mount Relocation

Tundra Cab Mount Relocation Kit – 2007–2021 Toyota Tundra

The Strongest CMR Kit on the Market

The DRT Fabrication Tundra Cab Mount Relocation (CMR) Kit is the ultimate solution for running 37” tires on your 2007–2021 Toyota Tundra. Factory cab mounts (or body mounts, also known as BMC) don’t provide enough clearance for larger tires, and even a traditional “cab mount chop” often leaves rubbing issues. Our relocation kit completely moves the cab mount behind the firewall, providing the clearance you need without compromise.

Why Choose DRT’s CMR Kit?

• Unlike standard kits, ours is built for maximum strength and long-term reliability:
• 3/16” frame overlay plate disperses load and prevents stress cracks
• Fully boxed design built from laser-cut 3/16” & ¼” plate steel
• .188 DOM tube housing with Polyurethane bushings included
• The only fully boxed cab mount relocation kit available, making it the strongest on the market

Key Benefits

• Clears 37” tires without rubbing
• Provides a stronger, more reliable solution than standard “chop” methods
