2020-2024 GM Duramax 6.6L L5P Front Gears

It's easy to add larger tire and wheels to your 2020-2024 GM Sierra/Silverado 2500/3500, but it's a lot more difficult to win back the performance and acceleration after your change in final drive ratio. These premium front gears help you and your truck win back the performance and acceleration lost from larger tires, giving you a more consistent driving feel without compromise. Shorter gears can also give your GM 6.6L Duramax L5P equipped truck improved acceleration and torque delivery, which seriously helps out with off-road applications.
