Smooth Operator

Reviewed By Anthony A (SHALIMAR, FL) Reviewed for a 2012 GMC Sierra —10/16/2016 7:41 AM

What a difference a day makes! I installed this product as soon as I received it, and it has made a huge improvement in the way my truck drives. No more bucking and clunking, just plenty of power and smoother action all around. I have already recommended it to a friend of mine.

Easy to install simple to use

Reviewed By james b (Ashville, AL) Reviewed for a 2012 GMC Sierra —6/27/2016 2:49 AM

Haven't seen a major power difference but has definitely improved fuel economy. Only problem I've had with it is it has froze up on me twice.
