m1009 highways speeds

[motormayhem]

What can a m1009 do on the highway stock and comfortably for the truck? What can one with a 4" lift and 35's do?

 

[ragedracer]

I cruise mine at an indicated 65mph very comfortably. I'm guessing that that indicated 65 probably translates to between 55-60.

I have run it up to 85 stock tires, with the lift and tires I have only got it up to about 80, never a top speed run yet.

Went to PA and back a few weeks ago and she just hummed along at 75mph. 36's with 3.08's

3.08s? what does that refer to?

When I bought mine, I did the 1200 miles home from KS at roughly 75-80... It loved that speed.

 

[IRWFO]

3.08s? what does that refer to?
J

The rear end gear ratio.

The 3.08 refers to the OEM ring & pinion gear ratio.
All M1009 CUCV's have the same ratio in order to swap like parts from truck to truck. All M1008's are the same as all other M1008's as are all M1028 axles the same to each other as well.
This is way in a battlefield setting, an axle can be robbed from one "like vehicle" and put on another one in order to keep most of the ground fleet moving forward.
I have been driving my M1009 with 33 / 12.50 x 15 tires on the stock 15 x 8 wheels for 14 years. No lift was done, only replacing the 31 inche tires with the 33's. No fneder trimming although I don't do "extreme off roading" or "rock crawling" with it either.
I can cruise along at 70 all day long and creep up to 75 once in a while but the
engine RPM is a little high the fuel economy goes way down compared to 65 to 70 range. 68 MPH and I'll get 20 miles per gallon in my daily driver on the open road here in ultra-flat Louisiana.

I have to run down the highway about 12 miles to post everyday. If I take the back roads i can only get up to 65 but if I take the main highway we are hauling butt. I have my garman and it said 89 MPH one day. Bus most of the time its around 80-85 MPH.
If I were going on a long trip I would keep it around 65-70 all day and not think twice.

 

[motormayhem]

Is there a way to tell what mine can do without over revving the motor? The only time I need to go on the highway is to get to the mountains 200mi away. Also with the 35's should it be able to go faster or slower with 3.08's?

 

[AJMBLAZER]

Faster. The 35's have effectively raised your gear ratio to something in the 2.xx:1 range. Put some 38's on and you'd need a push start but could probably run Bonneville.

 

[AJMBLAZER]

His truck is already lifted on 35's I believe.

15x8's fit 35x12.5R15's just fine. Been done gazillions of times.

Regearing to 3.73 or 4.10's would be best along with fixing the speedo (although I haven't even done the later yet...45mph = 55mph ish)
