C4 Fabrication 4Runner TSS Sensor Relocation Kit

The C4 Fabrication 4Runner TSS Relocation Kit is a bolt-on 12-gauge steel bracket that moves the Toyota Safety Sense sensor behind the grille, preserving full TSS system function after an aftermarket bumper installation. Designed for 2020–2024 Toyota 4Runners equipped with TSS, the kit ships with all required mounting hardware and is available in raw steel or powder-coated finish.

Keep Your Safety Systems Online

Replacing a factory bumper with an aftermarket unit typically blocks or removes the mounting point for the Toyota Safety Sense radar sensor, disabling pre-collision warning, lane departure, and automatic high-beam functions. The TSS Relocation Kit solves this by moving the sensor to a new bracket position behind the grille, where it maintains the line of sight it needs to operate correctly. Buyers who want the protection of a steel bumper without giving up active safety features get both without compromise.

Fine-Tuning Built In

The relocation bracket includes adjustment range so the sensor can be dialed in to the correct alignment after installation. Proper sensor aim is critical for TSS accuracy. A fixed bracket with no adjustment would force a recalibration shop visit any time fitment varied slightly. The adjustable design lets the installer set alignment on the vehicle before finalizing hardware torque, reducing the chance of a calibration error.

Bolt-On with All Hardware Included

The kit is fully bolt-on and includes every piece of mounting hardware required for installation. No fabrication, drilling, or sourcing of additional fasteners is needed. C4 Fabrication manufactures this bracket in the United States from 12-gauge steel, giving it the rigidity to hold sensor position under off-road vibration and trail use.

Specifications

Who This Is For and Isn't

This kit suits 2020–2024 Toyota 4Runner owners with the Toyota Safety Sense package who are installing a C4 Fabrication Hybrid or Overland Series front bumper and need to retain full TSS functionality. It works with the standard and TRD Pro grilles.

This kit does not fit 4Runners without the TSS sensor package, and it is not compatible with C4 bumpers that include a mid-height bull bar. Compatibility with the Limited grille has not yet been confirmed by C4 Fabrication. Buyers choosing the raw steel finish will need to paint or powder coat the bracket before installation to prevent rust; C4 Fabrication recommends test-fitting before coating to confirm alignment.

Common Questions

Will my Toyota Safety Sense system still function normally after installing this kit?

The TSS Relocation Kit is designed to maintain full Toyota Safety Sense functionality by repositioning the sensor behind the grille at the correct location and angle. The bracket includes adjustment range to dial in proper sensor alignment. Whether a dealer recalibration is required after installation is not stated in the product data; consult a Toyota dealer or qualified installer if you are uncertain.
