2021 Tacoma Pro Red Coil Marking

Just curious as to why they mark these coils?

Looks like they were covering something up.

 

I have a very similar mark on my coils. I don't have a pro, just an Offroad edition. I suspect the mark is to verify that something is lined up? I bought the truck with 8 miles on it, so it has to be from the factory. The truck has never been in an accident.

 

Maybe they need a way to identify them?
A bit of red paint should solve your concern if you don't like it.

 

Don’t have any markings on mine. Maybe your taco was made on a Tuesday

 

Looks like stock upper control arm rubbed against the coils, likely while off roading and wheel droop
