Question for guys running 4.10's?
 

Ok for those of you that are running 4.10's do you race the 1/4 in OD or not in OD. Whenever im just driving around truck is in OD. Only time that it comes out is when i do a burnout and run the 1/4. So you guys running 4.10's what do you do and what are the RPM's at when you go through the traps. More then likely 4.10's will be my next mod.
Thanks

Vin- By using an RPM caculator I came up with running my Nitto 555R's (28.75 inches tall) with a 4.10 gear I can cross the line at 116mph at 5600rpm's in 3rd gear. This should be perfect and well into the 11's. You will really see a major benfit on the street with your 20's. You probably will end up with a final gear ratio in the 3.90 range if you run 4.10's with your 20's. Hope this helps.

Thanks sounds great to me. So then you run with her not in od correct. And when i race ill be using my 28" tall hoosiers so sounds like your calculations are right on for my track setup:rocker: .

I like running with the OD off when I run slicks.
My truck last year would not go in to 3rd with OD on but would yield a better 1/4 time with OD off.
