3.08 Gearing

Looking at reducing the 4.10 LS gearing in the F350 6.0L 6SP to 3.08.

From previous threads it appears that 3.08 gearing may be optimal for MPG with manual trans but it sounds like it is difficult to locate. Does this mean that it is not available OEM, aftermarket, Istambul, nowhere?

Can no aftermarket vendors be convinced that there would be a market for the 3.08 gears?

I have seen reference to 3.08 being available for Sterling gearing. Too new to the PS world to know about that. Can someone explain and indicate what year/models it was available for?

Re: 3.08 Gearing

I dont know of any gears that tall for a 10.5 sterling. You might have to add a gear vendor OD to get that kinda gearing. I think 3.55 are the tallest gears available.

My exhaust makes more horsepower than your import!

Re: 3.08 Gearing

I haven't seen them offered for five years. Maybe one of the PSN sponsors might know different.
