    Reccomendations PLEASE!!!

    Guys, I currently have 4.10's in my truck now, tryin to get the truck to a 7.1x, went 7.40@90 this past weekend in the heat, so what gear do you guys think will work the best? 4.30's or 4.56's? I know that the 4.30's wont be much difference but it I think it'd be a better street gear

    Well, it all depends on what RPM you're crossing the line at. You want it to be pretty much wound out as you're going accross the traps, bt then you wouldn't be able to make 1/4 passes and driving on the street would be a pain. So you just have to find a nice happy medium. Obviously the 4.30s would help some and the 4.56s would be even better, but since it is still street driven it's all a compromise...

    knowing your powerband would help in deciding what gears you need youre not gonna drop .3 by just a gear swap, you'll mph more and just maybe drop a tenth. think about working on the suspension, you'll see more gains..

    Yea, the suspension definately has got to have some work, gonna start that and weight reduction this weekend, but want a better gear also to help out on motor passes, it's so dead out the hole on motor

    have you ever dynoed the truck on nitrous? , what rpms are you crossing the traps? this is where your powerband comes into play, i mean yeah you can regear the truck BUT what if it then comes to be touch much gear? you have 4:10s now, you gotta know what your truck is doing, to get the fullest out the setup..


    truck'n from his sig and the times posted and being a 5.3 i think hes already running a 200 shot of nitrous

    Totally didn't see that, so sorry. Yes, knowing your power band is key. If you're doing 1/8th mile a tall gear is nice, but you gotta know your power band. If it's way high, get a high stall converter and a tall gear.
