2001 Chevy 6.0l gas torque curve?

Planning on towing my 6500lb trailer in the West VA mountains and looking for a torque curve for my 2001 suburban 6.0l (gas). It’s ok in the VA mountains but will be “stretching it out” in the WVA mountains. Would be good to know the optimum RPM range.

Finding lots on everything but; anyone have one or know of a source?
  • I tow with the same motor and I don't worry about using high RPMs to get our 9K# rig through the Mountain West region of the country. I find ultimate power is available in the 4K to 5.5K rpm range. We predominately camp the four corner states and live at nearly 6K' elevation making all of our towing at high elevations.

    Although gas engines suffer a 3-percent loss per 1K', I just rev her up and she always pulls us through. If I have towed through the area before I anticipate climbs in elevation utilizing momentum to minimize extreme RPM scenarios, usually have no problem maintaining posted speed limit. I do have a scan-gauge to keep an eye on tranny temps.

    My previous TV was a 2005 2500HD with the 6.0. You'll spend much of your time in second gear in the mountains. Don't let the high RPM's scare you.


    Thanks!
    Lots for great info; determined mine is a LQ4 from the vin.

    I see the curve for the LS2 - 2005 Chevy SSR (truck). Probably similar; would love to have a curve for my exact engine.

    Graph pic doesn't want to post nor does the http address due to length. However, the graph shows the torque curve peaks at around 4400 RPM and approx 375 ft lbs or lbs feet. You should have plenty of engine output to easily tow 6,000 lbs in WV as the tranny will downshift as needed for more grunt. Assuming you have the auto tranny.

    Peak HP is at about 5500 RPM

    I don't have my engineering manuals handy right now but the numbers seem about right as I can remember.
  • I too have the 6.0 in a 2001 2500HD Silverado. You will be in the high RPM's, just watch your gauges. My tranny gets a bit hotter than I would like, so this year I am adding an extra tranny cooler which will more than double cooling capabilities. These motors are built tough and that's where they make their power, not like a diesel down low.
