Maxtrac 2/4 help

[Slap]

I have a 2024 Laramie just installed a maxtrac 2/4 drop and a spohn adjustable pan hard bar . Problem is at about 15mph I have a vibration both taking off and slowing down any ideas on what could be the problem?

Is the vibration happening only under acceleration and deceleration, or also cruising at 15 mph? Does it go away over 15 mph?

A few more questions.

1. Did you wait to tighten all of your suspension bolts after the truck was sitting on the ground (under load)?
2. Did you ensure that your rear wheels are centered, and not shifted to one side?
3. Did you get an alignment done on your truck after lowering it?

Had a shop here locally do it
Checked the wheels even tried putting my stock wheels back on same thing .

Alignment was done

It starts about 13 mph to about 20 then goes away both accelerating and decelerating

Oh, if a shop did it, hopefully they did everything right. Maybe a pinion angle issue. You might have them check that.

I suggest contacting Maxtrac. This might be something they have heard of before and know a solution.
