Upgrading the driveline on your 2020-2025 GM Sierra/Silverado 2500HD/3500HD can make a significant difference in overall ride quality, especially if you’ve added larger tires or want to improve off-road performance.

Installing more aggressive gears allows your truck to compensate for larger tires, restoring off-the-line performance and optimizing power delivery for towing or off-road adventures. Aftermarket differentials deliver improved traction, ensuring your custom-built GM 6.6L Duramax L5P can handle challenging terrains with ease.
