Has anyone been to the track with only the gear change?
Or raced two identical trucks with different gears?
What are the 1/4 mile time differences?

I know a couple guys with stock ccsb 5.3 trucks with 4.10s.
I might end up racing them soon.

 

i have had 3.42, 3.73 and currently 4.10's. i don't consider gears as something to make you faster. quicker only by a little bit. i look at gears as more of a daily driving mod. to me my 4.10's make daily driving so much better in the sense that i don't have to half throttle it or full throttle it to get moving like i used to have to do with the smaller numerical gears.

some people get about a tenth or two from a gear swap.

 

i dropped .5 in the 1/4 going from 3.23s to 4.10s

 

With what size wheel/tire if you don't mind me asking...

 

with 3.42 to 4.10 your looking at about 3 tenths faster.

but do you have a pic of your intake tube? also what did you use to make it?
Are your tbar keys cranked?

 

new thread on tube.
Yup Tbars are adjusted a bit.

 

Noticeable difference. About 3/10 quicker E.T.s A must for a heavy truck.

 

stock aluminum 17's with 245/70

 

i went from 15.276@88.96 to a 14.767@92.76 doing the gear swap only

 

That post is a perfect reason why everyone should get 4.10's!!
