Alright..new 4.88 gears, how fast am I going...

[Kyle M.]

I have 33's and some 4.88 gears. How fast am I going according to rpms(can you tell me 65mph?). I can't really find a calculator to help me figure the gear along with the larger tire. Thanks

2600 RPM = http://www.csgnetwork.com/multirpmcalc.html

The 5 speed option is .01 within the M5OD's overdrive. If you want to change the overdrive ratio (different tranny = NV3500's is .74) use the lower calculator.

I know I've seen a calculator someplace, I'll look around for it but someone else will probably beat me to it.

I take it you have no GPS....

Calculator works good, thanks. I have the M5OD, so what is the final OD ratio?

 

[Kyle M.]

Alright, I got it, .79
