I am looking for a gear speed calculator with the gear ratios of the G360 5 speed. I have an excel spreadsheet calculator which works great but it only includes RPM speed calc data with rear end ratio and tire size for NV5600 5 and 6 speeds and NV4500. Are the gear ratios similar between the G360 and NV4500?

BILTIT

Getrag G360 5 Speed Gear Ratios:
Gear:
1 5.53
2 3.02
3 1.60
4 1.00
5 0.77
R 5.03

NV4500 Gear Ratios:
(95+ GM, all Dodge)
Gear:
1 5.61
2 3.04
3 1.67
4 1.00
5 0.75
R 5.61*

*Reverse changed to 5.04 approx. 1998 model year.

What exactly do you mean by a gear speed calculator?


A ton of calculators here:

Thanks. Since I don't currently have a tach in the truck I wanted to find out the max speed in each gear given 3,000 RPM, 4.10 gears and my current tire size.

84 mph if you have a 29" tall tire and 87 mph with a 30"

Down at the bottom, the last three options have good calculators for figuring RPM, speed, and tire size.

Perfect, thx!

My tire size is 235 85R 16 but I am not sure of its size in inches? I believe it is close to a 31"?

BILTIT

Specification Sidewall Radius Diameter Circumference Revs/Mile

285/85-16 9.5in 17.5in 35.1in 110.2in 575

but i think you meant 285/65-16 which is:



Specification Sidewall Radius Diameter Circumference Revs/Mile

285/65-16 7.3in 15.3in 30.6in 96.1in 659

so yes 30.6, close to 31.

I will double check today but I am pretty sure the outside dually tire I was looking at stated 235/65-16. If correct, I take it that would be quite a bit smaller than 31? Also, I do remember that the factory door sticker stated truck came with 215's
