Individual trailer TPM$

[MPark]

When I ordered my tremor back in December I added individual trailer tpms because it was only $50.

I'm looking at the site to build checking different confirmations and now it's up to $459, anyone know whats changed?

on my dealer build sheet it's still listed at $50 so I'm hoping theyll honor it

Maybe the $50 option is just for the plug, and the $459 kit actually includes the trailer tire sensors?
