True North Fab Hybrid DIY Rear Bumper – Installation & Fabrication Guide

How To Weld & Install The DIY Hybrid Bumper From True North

True North offers the bumper in a couple of configurations; with or without a swingout and welded or non-welded (DIY). It starts at $699 and can go up from there depending on what you option; swingouts, swingouts with MOLLE, powder coating, etc.

We are working on the DIY option today without a swingout welded together by the boys at StellarBuilt. Let’s jump into the installation and see what it’s all about.

    Step 1. Tack Weld Hitch Assembly

    The hitch assembly is keyed for easy assembly. Everything slots into place and is ready to tack.

    Step 2. Finish Weld Hitch Assembly

    Step 3. Inner Hitch Tube Support

    Once the hitch assembly is welded, mock up the inner tube supports.

    You may need to sand down the inner tube supports so that they are flush with the hitch plate and receiver.

    Step 4. Outer Hitch Tube Supports

    Weld the outer tube supports to the outside of the hitch plate.

    Step 5. Prep Frame Plate Assembly

    Now let’s mock up the frame plates. You will have a driver and passenger side frame plate.

    Step 6. Frame Plate Reference (Driver & Passenger)

    This is how both the driver and passenger side frame plates should look. The Frame Plate, Vertical Gusset, and Top Plate are ready for final welds.

    The frame plates are made of 5 pieces:

    1. Frame Plate
    2. Vertical Gusset
    3. Top Plate
    4. Recovery Overlay
    5. Frame Spacer

    Step 7. Recovery Overlay

    True North provides recovery plates with their logo for each frame plate. Line up the holes for the recovery point, clamp it together, and weld.

    We got two driver-side recovery overlays. Not a big deal. It’s the same piece but the logo is now reversed on the passenger side.

    Step 8. Frame Spacers

    The last step for the frame plates is the spacer. Both the driver and passenger side get spacer plates.

    Step 9. Mount Frame Plate

    Now that the frame plates and hitch have been welded, bolt everything on and set the tube in place.

    Step 10. Level Tube

    Roughly fit the tube to your desired position with a few clamps. Level out the side tubes on both sides.

    Step 11. Measure Tube Offset

    Finally, measure the distance from the body to ensure your tube has been centered.

    Step 12. Primary Support Brace

    Position the primary support brace in the slot on the frame plates and slide it into position along the tube.

    Step 13. Secondary Support Brace

    Slide the short brace in between the long brace and tube until it becomes tight.

    Step 14. Tack Weld Center Tube on Hitch

    Once all the pieces are in place, start tacking everything down. We started with the tube and hitch and worked our way to the outside.

    Step 15. Weld Frame Plate to Tube

    You can weld the tube to the frame plates while mounted to the truck or pull it off and finish welding everything together.

    Step 16. Remove Bumper – Finish Welding

    For the hard to reach welds, we pulled the bumper off the 4Runner, and finished everything on the table.

    Step 17. Dimple Plate

    The dimple plates are welded to the recovery plates, frame plate, tube and hitch.

    Step 18. Shave Frame Plate

    You may need to shave a bit of material off the frame plate for the dimple plate to seat correctly.

    Step 19. Weld Dimple Plate

    Once you have it tacked up, finish welding.

    Step 20. Weld Tube Caps

    The last step for welding is the bumper caps.

    Trimming Side Bumper: 10 5/8″

    Please take your own measurements. These may be different for you depending on how you set your bumper.

    Bumper Corner: 2 3/8″

    Rear Bumper: 1 3/4″

    Measure Twice Cut Once

    Weight: 46.7 lbs

    We weighed the bumper after everything was welded on and it came out to only 46.7lbs!! That’s wild. This has to be one of the lightest bumpers ever made for the 5th Gen 4Runner.

    Final Thoughts

    Light Weight Rear Bumper 5th Gen 4Runner (Only 46 lbs)

    If you’re a beginner welder, this is a really simple project. This bumper took CJ (Stellar Built) about 4-5 hours to weld and I spent another hour trimming and fitting the bumper in place.

    Here is the product review. In that post, we covered all the features, fitment, pros, cons, swingout options, and much more.
