2014 GMC Sierra SLE 4.3 V6

Reviewed By Gary W (READING, PA) Reviewed for a 2014 GMC Sierra —12/7/2017 3:43 PM

I've only had it installed for 5 days so far but it is working as advertized. No more annoying V4 or the vibration that comes with it. Very happy with Range so far. I hope it keeps up, I don't see any reason why it would change.
