2020+ 5th Gen 4Runner TSS & Bumper Compatibility: Everything You Need To Know
Do you have your eye set on a new bumper for a 2020+ 4Runner?
For those interested in adding in a new bumper for a 2020 4Runner know there are some new challenges with this model year. Specifically, the Toyota Safety Sense (TSS) sensor in the front bumper has to be compatible with the new bumper. If you want to find out other differences with the 2020 4Runner check out Top 5 Differences in the 2020 4Runner.
As of now, I could not find an option that allows the replacement of the whole bumper and relocates the TSS sensor. C4 Fabrication has uploaded a YouTube video showing a sneak peek of a relocation kit of the TSS, but there is no mention of a release date.
Please note: If this sensor is moved, then a certified Toyota technician would need to help recalibrate this device.
What is the Toyota Safety Sense (TSS)?

The Toyota Safety Sense is a new system developed to make our driving experience safer. The features of this safety system include pre-collision braking with pedestrian detection, lane departure alert with sway warning, automatic high beams, and High-Speed Dynamic Radar Cruise Control (DRCC or known as adaptive cruise control). For this article, the part of the safety system we are focused on is the radar on the front bumper. This radar is crucial to help with pre-collision braking with pedestrian detection and adaptive cruise control.
TSS Compatible Bumpers?
Thankfully, there are two main bumper options avliable that are compatible with TSS; low profile and hidden winch mounts. Companies offer these styles for 2020+ 4Runners who are looking for the functionality of an aftermarket bumper yet looking to retain TSS, however currently no company offers a full width bumper.
Hopefully, companies will start to develop a compatible full bumper replacement compatible with TSS soon.

We will update the post if and when companies start to release TSS relocation kit or compatible bumpers.
Low Profile Bumpers
As many have likely seen, low profile bumpers require cutting the front valence out and using most of the stock bumper. The benefits can include recovery points, a light bar, bull bar, winch, and a change in the aesthetics. For this article, we won’t go into all the details about these bumpers. However, I will highlight the choices you have compatible with the 2020 4runner TSS.
Below is a list of compatible bumpers for 2020 4Runner that I have found when researching options for myself. The list below does not include every option available, and the order does not indicate one bumper better than another. Also, the bumpers do not include options for the Limited models.

Additional Steps for Removing the Bumper
So you have found that sweet new bumper and can’t wait to get it installed?
Well, with those lead times you’ll probably be reading up on how to install your new bumper. Brenan has written an excellent step-by-step article on how to remove the bumper in the C4 Fab Front Bumper Install.
However, with the 2020 models, there are two additional bolts that must account for before fully removing the bumper. These are two 10mm bolts and differ from the other bolt shown at the top of the image.
Try to avoid mixing these up as they are both 10mm bolts and look similar. The difference is the washer on the bolts.
Installing/Removing Low Profile Bumper with Tall Bull Bar
As a side note, the bracket attached by the two bolts can be a challenge when installing/removing the factory bumper back on the vehicle with a low profile bumper that has the tall bull bar.
The reason is the bull bar potentially doesn’t give much space between the front of the vehicle for the bumper to fit. The bracket then becomes an issue because it sticks out so the bracket has to fit over the black horizontal bar you see right above it.
One could remove the TSS bracket but I didn’t want to risk the TSS moving and needing to recalibrate the TSS after removing and reinstalling.
Remember to disconnect the cable to TSS before removing the bumper…
Also, the cable connecting to the TSS must be disconnected before you can remove the entire bumper. While not required, I found first removing the connector from the bracket makes disconnecting the cables easier. Once those bolts are off and the cable is unplugged you are set to trim the factory bumper and get your sweet new bumper installed!
The TSS is a great safety feature and one where a hidden or a low profile bumper is going to be your best option to add a winch, light bar, and additional recovery points. Since a full bumper replacement is out of the question, you may consider a high clearance cut to compliment the low profile bumper.
For now, we will have to wait on those full bumper swaps until companies can integrate the TSS.
