Description
The Right Gear Ratio. Most people pay little to no attention to their driveline and gear ratios. They trust that what is sitting on the lot all shiny and new is the perfect vehicle and it will do what they want it to do. While this is true to a point, there are differences in gear ratio that can make a lot of difference when it comes to your GMC Sierra 1500. This is why most truck manufacturers offer different gear ratios. The lower the number, the lower your RPMs will be at speed and this can translate into significant differences in gas mileage. If you are going to be mostly driving your truck on roads then the Motive Performance 8.5 in. & 8.625 in. Rear Ring Gear and Pinion Kit - 3.42 Gears is going to be a great choice for you for better mileage.
Computer Controlled. Motive Performance uses the latest in technology to manufacture its gear sets. Made from first run 8620 steel and then heat tempered under computer controlled conditions, these gear sets are durable, hard and precision made.
