4:10 gears
Thinking of putting 4:10 gears in my 91.....Are viper gears the preferred choice? What do I exactly need? Who has the best price for parts and what exactly do I need?
Thnx... |

Re: 4:10 gears
No gaskets, RTV for the cover. Being my ZR-1 is stock it was a worth while mod.

Re: 4:10 gears
John, can i ask why you want 4.10's?
You'll be sliding/spinning tires. I just finished my 391ci stock gears,new Nitto Drag Radials and it's a smoke show. Pete

Re: 4:10 gears
I have to agree with Pete too, if you have a modded motor, unless you have wheel like Dominic and need the gear to compensate for that, Stock motor the 4.10 is a fun mod and worth it.. on a modded motor it might be too much

Re: 4:10 gears
Despite Pete's preference for 3.45s for drag racing. I think 4.10s were one of the best mods I did on both of my ZR-1s (along with the Hurst short shifter set up to look stock). One car had about 450 HP and one had closer to 500. Really made around-town street driving better . Face it, 99% of the time you will not be applying full power on every takeoff. If you are drag racing you can lug the engine a bit at the start, although you will need to shift to 4th in the quarter mile. For the three or four times I actually drag raced my cars it was fine with me. Not trying to set any records, just have fun. Depends on your goals for the car and your typical use. Your mileage may vary.--Bob

Re: 4:10 gears
=Jeff= is correct. With 19s in back, you'll want 4.10s which has the rear simulating ~3.53 gear with stock wheels. How about maybe 3.73?

I know it would help with 6th gear cruising but most of the time I'm on the highway I'm using 5th.... |
