Converting a 2019 W900 3 axle to 4 axles

There are Lift axles with smaller wheels that are for 20,000 lb.

I have one that I would sell but it's old and needs some work and that's probably not what you're looking for.

But they do exist.

 

Hello Hegemeister, I have a nice Rodgers Jeep for sale, I'm about 100 miles from you.

 

Make sure you read up on the requirements for getting your lift axle certified for California before you run off and load for California. Also, it would be a good idea to get familiar with the AZ tridem weight limits and what routes you can get the tridem bonus on....

 

I looked into adding a pin on to the rear of one of our trucks, but after talking to people that have ran them, I decided against it. With the lift in the rear, steering can be a problem. Especially on jobsites and loaded heavy you can't steer with the lift on the ground. If your 5th wheel is set properly to load the truck right, and you raise your lift, it will make your steer axle light, and you still can't steer. Now I guess you could go with a steerable lift in the rear, and that would help out a bunch, but it would still be apt to hang you up on jobsites, because you couldn't raise it and still steer.

That is the main difference. When your lift is in the front, raising the axle puts more weight on the steer. When your lift is on the rear, raising it will make your steer light.

 

Double frame is better, but you see plenty of 4 axle trucks running with a single frame.

 

Interesting...

 

We run 5 axle trucks with a lift in the front and the rear and I’ve never had steering issues with the lifts up or down and I’ve taken some heavy ### loads up some pretty knarly mountains and ####ty locations in the patch. I have noticed a little bit of steering push but no worse than any truck loaded heavy.
