1600's on m923a2

[SCRAP]

Truck already has 1400 super singles, what neccesary mods does it take it to1600's without rubbing? How do you correct speedo? Any downsides at all....?

less pulling power

They will go on and shouldn't rub at all .

No mods needed.

Run them with a GPS and make a mental note of the speed difference between the GPS and speedo.

I have heard there is a considerable drop in performance.

That's good to hear. I was also considering making the swap. I had seen people do it but I never bothered to ask about rubbing issues.

This is correct. You are going to kill whatever power that 6CTA had. I know a guy who put them on his M923 and hated it according to what he told me (he is on this list so maybe he will chime in). He actually told me he was fearful pulling out into traffic because the truck was such a dog until he put 1400s on it.

Im sure its even worse with the NHC-250 in the A1's. Hmm that just might change my mind. How does an A1 do with 1400s?

I have had plenty of M939 series trucks with 1400s and never really noticed any problems power-wise. Sure, you have more torque with the 1100s, but the trucks don't really seem to suffer from the taller 1400s.
