    Hi, Most of the trucks came with 4.11 ratios. It will make the motor “wind out” but the ratio should have nothing to do the truck “Shaking”. You can call me directly to talk if you would like 800-999-2438 ext 102. Thanks

    I have a 1952 Chevy 3600 Pickup with a 235 ci straight 6 engine. The Engine is (I believe) from a ’53 or ’54. My issue is not power, but being able to convert the available power from the engine to something useable. Right now I can’t get the truck up past about 40 MPH without the rear end shaking violently. I’ve been told this is because the original trucks were never meant to go that fast, and their gear ratios max out at about 40 or 45 MPH. I’m not a gear head (though I wish I was) so I don’t know if this is correct or not. So my main question is what do I need to do to make the truck easier to drive at higher speeds?
