Description
Economical High-Performance Gears. If you want to sport bigger tires without losing stock performance, you have to upgrade your ring and pinion gears. Fortunately, there are a lot of options in the market and you don’t necessarily need the most expensive set. Take a look at this 9.5 in. Rear Ring Gear and Pinion Kit with 4.88 gears. This affordable high-performance gear kit is great for larger wheels, especially on the highway. It compensates for the lift and larger tires so you don’t lose too much fuel efficiency and top cruising speeds.
Impressive Quality at Surprising Prices. This 9.5 in. Rear Ring Gear and Pinion Kit is made of the same materials as more expensive options. The gear set is made of forged 8620 triple alloy steel. Each gear undergoes state-of-the-art machining to achieve the prescribed clearance and tolerance required for the gears to rotate smoothly.
Retuning Recommended. Whenever you change your gear ratio, you need to have your speedometer recalibrated. Use a tuner or a recalibration device to update your speedometer after the new gears are installed.
Body Shop Installation. It’s ideal to have this 9.5 in. Rear Ring Gear and Pinion Kit professionally installed. Since the use of special tools and equipment are required, an experienced mechanic is the best person to do the installation.
Warranty Statement. This 9.5 in. Rear Ring Gear and Pinion Kit comes with a 1-year warranty and it covers material and workmanship issues. Excluded from the warranty are damages caused by shipping, mishandling, installation, and normal wear.
Technical Note. In every gear change, check to make sure your front and rear axles have matching or close to matching gear ratios. Engaging 4WD while on mismatched gear can cause damages to your truck’s drivetrain.
Application. This 9.5 in. Rear Ring Gear and Pinion Kit fits 2007 to 2013 GMC Sierra 1500 models.
