i really dont like the stock 3.55 rearend gears... what do yall think would be a good upgrade... 3.92s or what. the 4.56s derrick uses seem a little much.

 

3.92 if you do alot of highway otherwise 4.10s if you're not fond of 4.56s

 

get 410's in my opinion.

when i get a new torque converter + shift kit, i'm gonna try my truck with the 410's.

my 456's are awesome and all, and as you can see from my track times (there is a thread somewhere on page 1 or 2...i bumped it back up), my 1/8th mile is pretty damn good...then, it slows down because my v6 can't keep them gears spinning at high speeds. so, we'll see. i'd say 410...with a 392 (if they make the 9.25" gear) u won't notice it all too much i bet.

 

as for highway driving, you'd be fine with the 410's. even with my 456 i'm fine. i was expecting to be redlining at 60mph...but it isn't the case. i have some videos on you tube...look up derricksmash on youtube.

 

what do you run on the 1/8 mile...do you think these truck are better siuted for that?

 

****...maybe?

put a 512 in there and make it an 1/8th mile v6 =)

dunno...i am about to bump a few threads to top of page...look at them...tons of timeslips in them.

 

I have 410 in beacuse I had it lifted on 315s. I just put it back to stock and have been driving it daily. I went with a 265 tire and at 70 on the highway it isn't bad. I do not have a tac, so next time I drive it I will hook my scanner up and see what I am at around different speeds and post them.
