Nitro Gear & Axle 4.56 Complete Front and Rear Ring and Pinion Gear Package

2015-2019 Chevrolet Colorado / GMC Canyon

When adding larger tires to your Canyon or Colorado, its imperative to change your ring and pinion ratio in order to maintain your power.  With the addition of larger than stock tires, your RPM drops off when compared to the same speed with the original tires, causing a sluggish feeling, both on and off-road.  Nitro makes the best gears in the business, so no better way to ensure you upgrade your rig right.  This kit comes complete with front and rear 4.56 ring and pinion as well as all of the necessary seals, races, bearings and other small parts for a complete package.
