C4 Fabrication Overland Series Rear Bumper for the 6th Gen 4Runner
The 6th Gen Toyota 4Runner brings a completely new platform to one of Toyota’s most capable off-road SUVs, and for owners planning to push their 4Runner beyond the pavement, protecting the rear of the vehicle is an important part of the build. The C4 Fabrication Overland Series Rear Bumper for the 2025-Current Toyota 4Runner replaces the vulnerable factory rear bumper area with a heavy-duty steel setup designed around protection, clearance, recovery, and additional lighting. With its low-profile design and 3/16-inch steel construction, it’s a serious upgrade for 4Runner owners building their SUV for technical trails and overland travel.
Heavy-Duty Rear-End Protection

The factory bumper works well for everyday driving, but taking your 4Runner onto more difficult trails introduces rocks, ledges, brush, and other obstacles that can quickly damage factory components. C4 Fabrication builds the Overland Series Rear Bumper from 3/16-inch laser-cut P&O steel, backed by 1/4-inch steel mounting brackets. This creates a much stronger barrier between the trail and the rear of your 4Runner.
That added protection becomes particularly valuable on technical trails where the rear of the vehicle can come into contact with obstacles while climbing or descending. Instead of worrying about damaging factory plastic every time the trail gets tight, the C4 bumper provides a purpose-built steel structure designed for demanding off-road environments.
Improved Departure Angle

Protection isn’t the only reason to upgrade your rear bumper. Ground clearance at the back of an SUV can have a major impact on how confidently you can approach steep obstacles. The C4 Fabrication Overland Series Rear Bumper uses a low-profile design intended to maximize the 4Runner’s departure angle.
A better departure angle can reduce the chances of dragging the rear bumper when coming off ledges, climbing through steep transitions, or navigating uneven terrain. For lifted 6th Gen 4Runners running larger tires and more capable suspension, upgrading the rear bumper can help the rest of the vehicle take full advantage of those modifications.
Built-In Recovery Points

Recovery equipment is an essential part of any serious off-road build, and C4 integrates heavy-duty recovery points directly into the bumper. 3/4-inch-thick D-ring tabs come standard and are fully welded on both the front and rear sides for additional strength.
Having dedicated recovery points at the back of the vehicle gives you another option when dealing with difficult trail situations. Whether you’re helping another vehicle or your own 4Runner needs assistance, properly designed recovery points are a valuable addition to a trail-focused setup.
Add Auxiliary Rear Lighting

C4 also designed the bumper with auxiliary lighting in mind. Two integrated pod-light locations are specifically designed for Baja Designs S2 Flush Mount lights, giving you the ability to add significantly more usable illumination behind the vehicle.
The mounts can also accommodate Rigid SR-M 2x3 and Extreme LED 2x3 flush-mount lights, giving owners multiple options when choosing their lighting setup. Rear-facing auxiliary lighting can be extremely useful when backing down dark trails, setting up camp after sunset, working around the vehicle at night, or simply improving visibility while navigating off-road.
Keep Important Factory Features

One concern with installing an aftermarket bumper on a modern vehicle is losing the technology built into the factory setup. C4 designed this bumper to retain several important features of the 2025+ 4Runner.
The bumper retains the OEM parking sensors and blind spot monitoring functions, allowing you to add substantial off-road protection without giving up those factory systems. It also retains access to the factory hitch, which is especially important for owners who tow trailers or use hitch-mounted accessories.
The mounting system also allows adjustment in multiple directions, helping installers dial in the bumper’s positioning for proper fitment on the vehicle.
Built for a Complete 6th Gen 4Runner Build

Another advantage of going with C4 Fabrication is the ability to build around a larger ecosystem of 6th Gen 4Runner accessories. The Overland Series Rear Bumper is compatible with the C4 Summit Hatch Ladder, making it easier to create a cohesive overland setup as your build progresses.
For owners starting with basic protection and eventually moving toward a more complete camping or overland build, compatibility between components can make future upgrades much easier.
Installation and Fitment

This is a substantial bumper upgrade, so installation is more involved than simply removing the factory bumper and bolting on the replacement. Installation requires cutting the factory plastic bumper, and C4 recommends having two people available for the process.
It’s also important to note that the bumper is not compatible with the kick sensor for the electric hatch. Owners with that feature should take this into consideration before purchasing. However, OEM parking sensors, blind spot monitoring, and the factory hitch are retained.
An optional two-stage hammer black powder coat is also available. Beyond giving the bumper a finished appearance that works well with the 4Runner’s rugged styling, the coating provides additional protection against exposure to the elements.
A Serious Rear Bumper for the 6th Gen 4Runner
The C4 Fabrication Overland Series Rear Bumper is an excellent option for 2025+ Toyota 4Runner owners who want to turn the new 6th Gen platform into a more capable trail or overland vehicle. Its combination of 3/16-inch steel construction, heavy-duty D-ring recovery points, improved departure angle, auxiliary light mounting, and factory-system compatibility gives the rear of the 4Runner significantly more capability without abandoning the features that make the new generation so useful.
Whether you’re preparing your 4Runner for technical trails, building a long-distance overland rig, or simply want better protection and recovery capability, the C4 Overland Series Rear Bumper provides a strong foundation for the next stage of your build.
