Regain the lost performance in your 2020-2024 GM Sierra/Silverado 2500HD/3500HD by upgrading to a set of aftermarket rear-end gears! Shorter gears help restore your truck's final drive ratio, allowing it to recover the acceleration and torque delivery lost with bigger tires. For those building a dedicated off-road rig, higher rear gears can offer significant performance gains, providing more torque and horsepower for conquering difficult terrain. Combine these rear gears with some Front Gears or Brake Upgrades to maximize the overall performance of your GM 2500HD/3500HD build. GM Duramax Fitments: 2020, 2021, 2022, 2023, 2024 GM 6.6L Duramax. Submodel Fitments: WT, Custom, LT, LTZ, High Country, 1LT, 2LT, Pro, SLE, SLT, AT4, Denali. Some exceptions apply, please see individual product pages for specific fitments.
