i want to purchase a spare set of 4 sensors to install in my aftermarket wheels. i dont want to use the ones from my oem wheel because i will be using them in the winter.

1. will this part number work? 56029398-AB (found on ebay) http://www.ebay.com/itm/120893749920#ht_1501wt_944

2. do all these sensors run off the same frequency/signal, or would i have to have a dealer program them? if its a dealer thing, do they have to program them BEFORE they go into the wheels?

3. do they have to be programmed for LF, RF, LR, RR? or how does all that business work?

 

Question 3 I can answer. you do not have to assign the sensors to a wheel location. after a few miles they'll have the correct pressure and the correct position. They do the same thing after a tire rotation as well.

 

I was led to believe that 3/4 and one ton vehicles do not have tpms sensors. Might be worth double checking. This info came from my dealer.

 

2500s have TPMS, 3500s do not.
