ok so first question... 3.73's or 4.10's? second question.....what is the difference between them anyways...oh ya for a 7.5"rear end

 

R u auto or manual?

 

Diffrence between the gears is about 300 RPM. At 65MPH 4.10s will be at 2500 RPM while 3.73s will be at 2200 RPM. With 4.10s u will like the performance but will hate the gas mileage if u drive a lot on the freeway. As far as city MPG with 4.10s goes its really good .

Auto:4.10s
Manual:3.73s

 

auto

 

Its cool ,I got an auto too with 4.10s ,man are they great lol,It feels like a whole new car and it accelerates fast ,its just an amazing mod.

 

This will give u an idea of how good the 4.10s are. This guy has a tune,intake and exhaust plus the gears

how bad are we talking about when you say bad mileage on the freeway? im leaning towards 4.10s but i juss wasnt sure what exactly they did...how much was ur installation?

 

Well there is a difference but if u dont do a lot of highway driving u`ll be fine.Go with 4.10s u`ll get more performance out of them ,as far as installation goes I paid 350 but u can find someone to do it cheaper. Also make sure u buy a limited slip differential to distribute power to both wheels.

 

Ya im looking still i found a whole bunch of t-loks but thats it....i hear t-loks are weaker n tend to snap if u have HP in upwards of 300

 

Yeah thats true,but if u dont planing on pushing your car that far u will be fine
