But, the Dorman TPMS (PN RNB-974-009) come with metal valve stems and are a fraction of the cost of the GM sensors at under $31. So I figured we’d give them a shot in the name of science.

Start TPMS service at the counter to avoid comebacks, protect trust, and educate customers on this vital safety system.
