Lowering a Peterbilt 379!!

Did you change bags or do anything other than moving hangers up higher. I'm interested in doing mine

 

Lowering the rear ends is not smart. First of all that 5th wheel needs to be a very small range of height above the pavement. Second of all you have a literal train of gears flowing power from the shaft back there, lowering the rears will cause you to suffer a failure back there that will totally explode your wallet.

You will impose more stress on your freight. Shake it up even more. Maybe even shake something loose in that tractor if you havent already.

 

Wh

what about the low low air leaf like on car haulers? I've heard the only difference was hangers mounted higher?

 

Car haulers are purpose built.

If you took a tractor and lowered it many people say you need to accomodate the steering, alignments etc on the front and then the final drives on the rear.

I did not say it's impossible. Just make sure when you drop that thing you do it proper so that all the drive train angles remain.

 

That's the only difference in mounting, but that changes many other things. To check and adjust drivline angles, read the attached instructions.

 

10-4 on that, I got a real good alignment shop near me that I use and I'm gonna talk with them about the angles before I dive off moving stuff around

 

By lowering the truck, and thus the center of gravity, how much faster can you take on and off ramps???

 

I would get an overinflate switch to push the bags up

 

why would you want it lower it's a truck not a gocart

 

Thanks for that. I will look over it. You wouldn't know if bags or anything else would need to be changed too?
