Chevrolet 1500 Differential Install Kit - Revolution Gear & Axle - 5.13 Ratio - `09-`13. This is a 5.13 ratio gear package from Revolution Gear & Axle engineered for 2009–2013 Chevrolet 1500 models, intended for drivers who want stronger low‑end response and improved towing capability from their driveline.

The package is specified for GM 8.6in to GM 8.25in independent front suspension (IFS) configurations found on 2009–2013 Silverado/Sierra 1500 trucks. It provides a direct swap to change your rear axle ratio to 5.13, giving more torque multiplication for heavy loads, off‑road use or when upgrading tire sizes. Built to the manufacturer’s tolerances, this kit is intended for installers who want a reliable gear set from a known supplier. Professional installation and setup are recommended to ensure correct backlash, preload and pattern for long service life.
