Chassis Hardware That Locks the Summit MKII Bull Bar to the Tacoma Frame
An ARB bull bar only carries load correctly when it is tied to the frame with the brackets engineered for that truck. This vehicle specific fitting kit, part number 6178569, supplies the steel brackets and fasteners that mount the ARB Summit MKII bull bar to the 2024 and later Toyota Tacoma chassis, keeping the factory airbag deployment behavior and driver assistance hardware working as designed. The bumper itself is sold separately.

FAQ
Does this kit include the bull bar?No. It supplies only the brackets and hardware that attach a separately purchased ARB Summit MKII bull bar to the truck.
Which trucks does it fit?It is built for the 2024 and later Toyota Tacoma chassis.
Will the airbag system still work?The kit is engineered around the factory airbag deployment system, so the truck retains its designed behavior when the bar is installed to ARB specifications.
Is welding or drilling of the frame required?No. The brackets use bolt on mounting points at the chassis rails.
What material are the brackets?They are heavy duty steel finished in black.
Do I need one kit or two?One kit covers a single bull bar installation on one vehicle.
Can I reuse the brackets from an older ARB bar?No. Fitting kits are specific to one bumper and chassis combination, so brackets from another application will not locate correctly.
Does it affect the front parking sensors or radar?The kit retains the mounting provisions the bull bar uses for factory sensor and radar hardware, which stay in their original positions.
Installation Instructions
- Read the ARB fitting instructions supplied with the bull bar and this kit before starting.
- Remove the factory bumper, crash beam, and tow points as directed, retaining the fasteners the instructions call for.
- Exchange the factory bumper support brackets for the brackets supplied in this kit.
- Mount the fitting kit to the chassis rails using the supplied high tensile fasteners.
- Fit the bull bar to the brackets, then check centering and height alignment before final tightening.
