I am not having much luck with getting those 4.10 gears in, the Baton Roughe SVt dealer sent the wrong gears so I am reordering.
I understand the speedometer will be off with the gear change,is that going to be my only worry? Is the computer tied to the gear change in any other way that will hurt the running of the truck.
Thanks for your input guys,
Alvin

 

Dogleg:

I have had the 4:10's for awhile now, the only thing "off" is the speedo. Under lite throttle it will shift early, mid throttle is ok, hard or full throttle is right to redline.

Jiga, What would the RPM's be at 158MPH with the stock 3:55's? The correct number for the 4:10's at 160MPH would be 5434RPM's right?

Thanks

 

Metallic Blue:

rpm's at 158mph w/3.55
6638rpm in 3rd
4647rpm in 4th "od"

rpm's at 160mph w/3.55
4705 in 4th

4.10's at 160mph
7764rpm's in 3rd
5434rpm's in 4th

Are you looking to do Silver State?
I know someone with a 6400 redline on their Lightning. But I'm not saying who
