CBI’s 2025 4Runner Build – Portals, 37s, and New Plate Bumper

[K2Runner]

CBI Offroad just put together one of the most insane 6th-gen 4Runners we’ve seen yet, and it takes the platform into completely new territory. This isn’t just a clean OEM+ build with wheels and armor; this is a full-on step into hardcore territory with portals on all four corners, 37s that completely change the stance, and a brand-new CBI plate bumper up front. The combination of clearance, width, and overall presence makes the 4Runner look and feel like an entirely different truck.

74Weld Portals

• Gear reduction built right in makes 37s feel way more manageable
• The clearance under the diffs is unreal to see in person
• Truck feels wider, more planted, and easier on the drivetrain

37x13.50 Toyo RT Pros on Black Rhino Wheels

• The stance is perfectly wide without being overdone
• Jumping from 35s to 37s makes the truck feel like a whole new build
• Completely changes the presence on and off the road

CBI Offroad Plate Front Bumper

• High-clearance design with tight fitment
• Integrated winch mount + soft shackle tabs
• Factory fog compatibility with aftermarket options
• Clean slot for a 20” light bar install
