Finally got around to installing the new CBI Super Stock Covert Bumper.

This is one impressive little bumper. Super low profile, incredibly simple installation, and fitment is perfect. Matches the body lines perfectly, price is on point... everything about this bumper is a win and will be for many years to come. CBI nailed it with this design.
  • Designed for the 2025 Toyota 4Runner
  • Steel: Welded 7-gauge and 10-gauge steel
  • Winch-Ready Design
  • LED Pod Light Compatibility: Accepts one pair of 2″ LED pods (Baja Designs S2 or Rigid SR-M)
  • OEM Look: Maintains a low-profile, close-to-OEM appearance while enhancing functionality
  • Increased Front-End Protection: Adds essential armor without compromising clearance or aesthetics
  • Skid Plate Compatibility: Works seamlessly with CBI skid plates or the OEM TRD skid plate
  • Integrated Recovery Points: Built-in recovery points accept standard shackles for reliable off-road recovery
  • Easy Installation: Bolt-on design with minimal cutting of factory plastics required
  • Durable Powder-Coated Finish: Black textured coating resists corrosion and stands up to the elements

Step 1. Lower front Bumper Clips & Bolts​

Remove all the 10mm bolts and clips holding the lower valance on.

Step 2. Remove Fender Well Clips​


CBI-Super-Stock-Install-6G4R-1.jpg


Remove the 10mm bolts and clips holding the felt liner, fender flare, and fender together. Your fender wells might look different since we have done some trimming to fit our 35" tires. Here you can see all the clips and bolts off with the liner separated from the flare.

Step 3. Pull Back Fender Flares​

Now pull back on the fender flare and access the 10mm bolt holding the side of the bumper to the lower headlight area.

Step 4. Front Bumper Side Plastics​

This part might be a little nerve-racking, although it's very simple. Just pull straight out on the bumper cover and release the tabs that slot into place. A quick pull is usually better than slowly pulling on the bumper plastics.

Step 5. Remove Passenger Clip​

CBI-Super-Stock-Install-6G4R-6.jpg


Unclip the light grey passenger side clip.

Step 6. Remove Driver Clips​

CBI-Super-Stock-Install-6G4R-7.jpg


Unclip both passenger side harnesses.

Step 7. 19mm Bolts on Crash Bar​

There are 19mm bolts holding the crash bar in place on the top and bottom. Remove all these bolts.

Step 8. Remove Crash Bar​

CBI-Super-Stock-Install-6G4R-9.jpg


Just pull straight out on the crash bar and set it to the side. You will not reuse this piece.

Step 9. Center Support Brace​

Remove the center support bracket.

Step 10. Prepare Bumper For Trimming​

CBI-Super-Stock-Install-6G4R-11.jpg


Set the bumper on a rug or something soft to prepare the bumper for trimming. Be careful not to damage any of the sensors or adjust the grille shutter or grille shutter harnesses. If you alter any of these, you may get some check engine lights after the installation.

Step 11. Remove Center Screws on Lower Valance​

CBI-Super-Stock-Install-6G4R-12.jpg


To remove the center lower valance, start by removing the screws on the lower and upper valance. I believe there are 12 total screws holding the top and bottom together.

Step 12. Separate Clips on Lower Valance​

CBI-Super-Stock-Install-6G4R-13.jpg


Once the screws are removed, loosen the tabs that are holding both the upper and lower valance together.

Step 13. Pull Back Lower Valance​

CBI-Super-Stock-Install-6G4R-14.jpg


The lower valance is sandwiched between the upper valance and the backside of the bumper plastics. You will need to turn the bumper over, and pull back the upper valance in order to pull out the lower valance.

Step 14. Separate Lower Valance Cover​

CBI-Super-Stock-Install-6G4R-15.jpg


Now, fully remove all the last clips holding the lower valance in place on the factory bumper plastics.

Step 15. Remove Lower Valance​

CBI-Super-Stock-Install-6G4R-16.jpg


The lower valance should be free to remove. You will not reuse this piece.

Step 16. Re-Secure Top Valance​

CBI-Super-Stock-Install-6G4R-18.jpg


Once the lower valance is off, re-secure the top valance back to the factory bumper plastics using all the screws and tabs.

Step 17. Trim Lower Valance​

CBI-Super-Stock-Install-6G4R-20.jpg


Here is a rough idea of the final cut line. Since we didn't have any installation instructions, we first cut out the center portion, did some test fitting, and then marked our final cut lines.

Step 18. Upper Valance​

CBI-Super-Stock-Install-6G4R-22.jpg


Be careful when cutting along the top line, not to cut this black plastic piece behind the bumper plastics. This black plastic piece will slot behind the CBI bumper, which provides support for the bumper's entire front clip.

Step 19. Test Fit Bumper​

CBI-Super-Stock-Install-6G4R-21.jpg


Once the lower valance and bumper plastics are removed and ready, clean your lines up with a flap disc if you're experienced, or just use some sand paper or a file.

Step 20. Mounting The Winch​

CBI-Super-Stock-Install-6G4R-23.jpg


CBI provides really good access for the winch bolts. Bolt on your winch and get ready to mount the bumper.

Step 21. Bumper Hardware​

CBI-Super-Stock-Install-6G4R-24.jpg


Here is the hardware provided by CBI + the OEM 19mm bolts on the top right. CBI provides you with the bumper and two sets of support brackets. One support bracket for the lower bumper corner in the wheel well, and another large L bracket that we did not use.

The 1" hardware + flange nuts go on the top of the bumper and mount from the top down.

The 1 1/4" hardware + flange nuts go on the lower portion of the bumper and mount from the front to the back.

Re-use the factory 19mm bolts where you can into the pre-threaded factory nuts.

The small carriage bolts are used to mount the side brackets that connect the CBI bumper to the OEM bumper plastics + felt liner.

Step 22. Dry Fit Bumper​

CBI-Super-Stock-Install-6G4R-25.jpg


Test fit the bumper into place and loosely attach your hardware all the way around.

Step 23. Mount The Bumper​

CBI-Super-Stock-Install-6G4R-26.jpg


Here is a look at how the hardware is mounted to the bumper and frame rail.

Step 24. Side Support Brackets​

CBI-Super-Stock-Install-6G4R-27.jpg


Mount the side support brackets with the carriage bolts.

Step 25. Final​
