70mph @ 2000 rpm ok?
 

hi,
just got my '05 RCSB with 5.3 and i was doing 70mph@2000rpm, so is that hi or low?

also can any one calculate my rear end ration based on this? tires are 265/70/17

thx

I turn 2700 at 70.. Your ok..

rear end ratio ? tires are 265/70/17

i turn 2000 @ 70 all day long in both of my trucks.
08 has a 6spd and 4:11s
94 has 4spd with 3:42s

Going guess you have 3.73

Why not look up the gear ratio RPO in glove box?

yes 2k at 70 is normal. i would also guess 3.73 gears depending on the tire size.

2k at 70mph is 3.73, unless you have tires that are way different than stock.

I run 2k & 80mph, but I'm a 6speed and 3:42's

Lucky sob :jest:

Im on 4:11s an turn 2k @ 70mph
