Cab Mount Relocation Kit – 2003–2023 4Runner, 2007–2014 FJ Cruiser & Lexus GX470

The Strongest CMR Kit on the Market

The DRT Fabrication Cab Mount Relocation (CMR) Kit is the proven solution for running 35” tires on your Toyota 4Runner, FJ Cruiser, or Lexus GX. Factory cab mounts (or body mounts, also known as BMC in the 4Runner community) don’t leave enough clearance, and even with a traditional “cab mount chop,” rubbing issues often remain. Our relocation kit moves the cab mount completely behind the firewall, providing the clearance you need for larger tires without compromise.

Built to Withstand Anything

• Unlike other kits, the DRT CMR system is designed for maximum strength and durability:
• 3/16” frame overlay plate disperses load and prevents stress cracks
• Fully boxed cab mount design (the only one on the market)
• Constructed from laser-cut 3/16” & ¼” plate steel
• .188 DOM tube housing with polyurethane cab mount bushings
• The strongest cab mount relocation kit available today

Proven Fitment, Trusted by Thousands

We’ve sold thousands of these kits and refined the design through multiple revisions to guarantee a perfect fit. Installation is straightforward and engineered to be as hassle-free as possible, so you can focus on building your rig instead of modifying parts to fit.
