| Overdrive for Allison by Gear Vendors
In a truck magazine I noted a new product from Gear Vendors for Duramax with Allison that will provide up to +20% better fuel mileage.
It bolts up in place of the 8 bolt tailstock and requires the drive shaft to be shortened. At the cost of diesel fuel and slightly over $3K for the unit, the math begins to look like a reasonable investment.
Has anyone tried one of these units?
If so, what have been the results? |
