alpha cruising speed??
 

Can anyone tell what max hwy cruising(not burning things up) speed for the alpha is???

thx

Re: alpha cruising speed??
 

I can cruise at 75 mph with earplugs. ;) Usually keep it between 65 and 70 in Oregon. It goes faster if you want to pass or speed up for a while. I haven't had mine during the summer yet, so I'm not sure if it heats up or not. From what I've heard, there isn't a problem with the geared hubs heating up at hi-speeds on the Alpha.

can you tell how many rpm s at 70??

thx

Re: alpha cruising speed??
 

About 2600 rpms. Why?

Re: alpha cruising speed??
 

thinkin about a 1, but don't know if I can commit to 70 on the hwy, so then i was hoping maybe the alphalpha was more forgiving on hwy

thx

I drove 55 mph on the highway in my 98. I know some guys that will cruise up to about 65, but that's about the highest you should cruise at in a stock 6.5L TD.

If you want to go fast on the highway, get something else and tow the HUMMER.

Rusty. The best thing to do would be to test drive one, if there's one for sale nearby. You can cruise 75 in an Alpha without any trouble, they're just noisy compared to an H2. They're kind of like a cross between a peterbuilt truck and a backhoe. Big and wide and cumbersome on the road, but at home in the dirt.:)

just remember the H1 wasnt ment for speed it a civilian version of a military vehicle made for rugged terrain, not exactly made for the highway

2006 Duramax Alpha is a hot rod, you can do 70-80 mph all the live long day, just make sure you service your driveline.

When we go out in big groups we tell the Alpha owners to keep it to 65 so us with the old 6.5's can keep up :)

The Alpha is super quiet compared to a 6.5, almost like a car.
