I just bought a 2008 Ram with a 3.7 and a 6 speed. I only need it for light duty. I drove it around town for prolly 40 miles and then took it on the road. Mileage was 22 mpg. When I get my lightweight boat, i expect to be in fourth or even third gear up hills. I'm very satisfied so far.

Every one I have talk with tells me that the 3.7 and the 4.7 was junk and I believe them cause my friend bought on a it was no good it had no power

the problem with 3.7 and 4.7 is, they have single valve springs, and are prone to dropping seats, rockers arms falling off, and broken springs. dual valve springs are a must in any American car driven in USA. our highway speeds, roadways, and traffic situation demands it.

Don't get the 3.7 stick with a 4.7 or the Hemi they both have enough power and tow capacity the 3.7 can only tell about 3,000 pounds if that sluggish no power whatsoever you do better Towing something with a Jeep Liberty I mean it is the same engine

My 3.7 2003 ram 1500 has 232000 on it and still runs great...oil consumption is becoming an issue ...Never a single engine problem ever... mine is a single cab with a short bed..(lighter than a 4 door/long bed) ,factory towing package...power is excellent (and I am a X drag racer)...fuel mileage has always sucked (maybe the tow package get's a lower gear?)..First Dodge I have ever owned and I would buy it again....had 148000 on it when I bought it....I do change my oil every 3000 miles without fail....

I absolutely love my 2007 Dodge Ram 1500. I bought it with 50,000 miles on it and I'm just about ready to turn 200,000 miles. Not one issue ever! And I hold my horses everywhere in a 2 horse bumper pull. I do have the factory tow package and that's all I've Ever Needed great gas mileage!

280k and have beat the absolute crap out of this truck. Owned since new and has never had an easy day, it pulls my 16ft form trailer, and trailer with concrete equipment more than it’s been unhook. So far I’ve replaced the battery. Ol gal starting to burn oil pretty good now, hate to see her go.

I have a 2005 single cab 3.7 V6. It has110,000 miles on it. I'm a contractor and have built many homes and jobs with it. Hauling equipment,loading it with debris, concrete, garbage etc. I work it hard . Had to replace the ball joints of course a Ram thing. Interior is still top-notch . No cracks in the dash . A slight tear in the seat but that's to be expected . Other than that basic maintenance. No major issues. Great truck

I have a 08 ram with 3.7 and 6 speed. I get 25 mpgs if I upshift. I've hauled over 5000lbs no struggling. Even though it's rated at only 3750 lbs. Great engine. Plenty of power.

I own a 2008 1500 3.7L. motor runs great but has no power up hills,even on the highway I have to down shift just to get up the hill. Would I buy another? no way! Also had to rebuild rear end housing after only 35 thousand miles.

do you know if they put a different ratio in the diff. stock is 3.21. if so then a 3.92 or even a 4.11depends on where you drive it. Check with the mechanic who rebuilt the diff see if they can help. would make a lot of difference


good to hear people putting high miles on them. 2 co workers with 3.7s dropped valves within months of each other. both at about 110,000 miles. I have 108k, worried a little, lol.

If your lifters gets to dirty you may get valve train tap replace the lifters before the rockers pop off.DO NOT let the motor run hot! That's the death of these motors. Valve seats fall out, oil pressure drops,springs snap,radiators crack,all kinds of mean nasty things happen when they get hot. Apparently some of the water pumps were sub-par and fail as soon as 60k (see the do not get hot clause). Other than that it is a bullet proof motor.
