Ok I got 2 different gears....new motive gears from craigslist. I got a 3.90 and a 4.10. which one is the best for the strip. I know the 4.10 makes 1st gear useless...lol. Which every one I dont use Im just gonna sell..i got a sweet deal on them.

 

They aren't that much different but the 4.10s will be slightly better for the strip. Are you putting these in your factory 10 bolt? Be prepared to break a rear.

 

Yeah its a crappy 10 bolt....but least i will have fun busting it. I was thinking 4.10 also.
