In addition to helping keep your truck on the road longer, something you're guaranteed to notice is the added bump in fuel economy. This is especially true for those making long commutes via highway. With the addition of a 6th overdrive gear you will run lower RPMs at highway cruizing speeds. The fewer RPMs you're turning, the better your fuel economy will be. Picking up even just a little bit goes a long way while putting commuting miles on your truck. You’ll also notice a significantly quieter ride after adding our kit to your truck. Road noise, engine noise, vibration, and harshness will decrease drastically, giving you a much more enjoyable ride.
