In addition to the five 2nd Gens I already maintain, a client just purchased a '98 2500 with V10 (aside: why do the V10s sound like fart cars from the Fast 'N the Feverish??)....and I see a load sensing rear prop valve? Was Iacocca trying to be a Toyota fan?

Our '02 CTD doesn't have this....so what years and applications got this overcomplication? (Some day I'll tell ya how I really feel). Do these leak and fail like Toyota?

 

I don't think the load sensing valves lasted long. They were more trouble than they were worth. I believe there was a TSB on them, that recommended disabling them, or bypassing them.

 

You can bypass them with just regular stuff from a non valve truck. I did on my 02 Cummins.

 

On my v10 I just took a zip tie and gave it full rear all the time. That with the bigger cylinders really helped with braking on these 35. Previous owner let it sag when it was lifted so it only had front brakes, which sucked.

Also the v10s sound ok with a big muffler. I am unsure if they are like the viper which fires 2 cylinders at the same time (which I suspect since they share coil packs) or if it is odd firing 45-90 splits. They are not even firing (72 degrees splits), to achieve that you need a counterbalance shaft like the ford v10. Basically it is 2 choked 4.0l 5 cylinders next to each other the same engine compartment.
