hey there. what rpm do your trucks run at 60mph in 5th gear with the 3.0
i run at 2500 but the speedo is off like 2.5 miles per hour faster.

 

70mph - 3k

i think when im around 60-65mph im at like 2500

Also, 45mph - 1900, i wish i had a 6th that was geared for highway speeds

 

im thinking that i might not have 4.56 gears if im running at 2500 rpm

 

I have 4.30s lol.

Do yo uknow what gears you have?

 

i was thinking 4.56 but speedo is off with 31s like 3 mph at 60 mph so im confused. looks like the last owner had a problem with the 3rd because there was diff oil caked on the 3rd, all over the gas tank and the bed when i bought the truck

 

awww.. 3.0 only?
sheesh
I run about 2500 with my 22re in 5th and about 2200 in 4th.

edit- got them backwards....
about 2500 in 4th and 2200 in 5th @ 60 MPH

 

When I had my 3.0, I was always around 2500-3200. Cruising between 60-70 I was able to stay at around 2500-2800.

and if you are running 31's, like I was...I found I was about 10% off. So at 60 I was going 66 and so on. Factory speedo was set to the lower stock tire..even though the optional FACTORY package came with 31's. Always found that weird.

 

70 is 3000 65 is 2750 ish with 4.56 gears 5spd and 3.4 in a 92 and 265/75/r16 tires really want a 6th gear...

 

no speedo says 60 but im really going about 57. so that means i dont have 4.10s. i must have the big tire package 31s 4.56. lol i should had thought it over before i posted the thread. my dads old truck a 92 with 31s was a dog, but mine rips pretty fast i pass many people on the hwy with ease.
