When increasing the tire size on your 2.8L Duramax, in order to maintain the drivability you experience with stock tires, its imperative to upgrade the ring and pinion ratio. And contrary to what many believe, this upgrade is relatively simple, yet can make a huge impact on overall performance of your ride. Further, this will reduce the strain on both the factory Dana 46 rear and the Dana 32 front differentials to ensure they last the test of time. As always, if you have any questions about what products are right for you and your 2.8L Duramax, do not hesitate to give us a call or send an e-mail to cs@dieselpowerproducts.com and we would be happy to assist.
