Not your average gear question... Ok well maybe...

[Adam95GT]

Well we have two sets of gears at the garage 3.73's and 4.30's

I wanted 3.90's or 4.10's since the car will still be street driven and cruised in...

Chris said i could have either set for free... and free is better then paying for gears... we have access to a lift right now so what do i go with???


Im broke so free gears are looking good.


going 60 in 5th with the 4.30's im looking at about 2300 rmp.

with 4.10's ist about 2100

3.73's little less then 2000

Do you ever plan on using a power adder like n2o? Do you plan on taking it to the 1/4 mile track? If so, the 4.30's would be too steep.

Actually, I think the 4.30's will be too steep either way unless you had a mod motor. I'd go with the 3.73

Of course im gonna run the car at the track.

Then figure out what your rpms will be in 4th gear at the finish line with the tire size you plan on running.

Do you know what rebuild kit parts i need.

 

[Last5.0]

To rebuild the track-lok?

I don't have any kit part #'s off the top of my head, but I'd just get the standard track-lok rebuild kit for about $60 along with a ring and pinion install kit. Might as well do the bearings and seals also while you have the axles out. I think you can get the install kit for about $60-80, or a deluxe kit that includes bearings and seals for about $120

You'll like the 3.73s better. I went from 3.73s to 4.10s and picked up maybe .15 at the track NA. And now running out of gear on a 100 shot. 3.73s are a great street-strip gear.

I'd do the 3.73s. I think the 4.30s are going to annoy the **** out of you.

I'd also say 430's are too steep for a street car

Well ......... If you had some really tall tires

If all you have is what's listed in your sig, then you don't need 4.30's. I have 4.30's in my street car and there has never been a time where the rpm's were too high but I also do not go much past 70 on the hwy. They were also the gear that my combo needed. So, just get whatever gear your combo needs.
