Question:

I have a 1990 lance m-2400 gvwr of 6400lbs. It is a tandem axle with axles under lead springs, fifth wheel with goose neck conversion. I pull it with a 4 door longbed 3/4 ton 4wd and it bounces enough to effect change the ride of the truck. I am going to rebuild my suspension on the trailer wether that is just new spring eye bushings or replace everything. My question is would you recommend the shock add on kit, and if so for just 1 axle or both?

Expert Reply:

When it comes to shocks such as # LC281255 I do recommend using 1 set per axle. Otherwise the axle without shocks would be subjected to more force which over the long term could give you additional, bigger problems.

Another issue that could be causing the ride quality problem is if you are using a 5th wheel to gooseneck adapter such as # AM3100. This type of adapter extends where the connection point normally is on a 5th wheel trailer to about a foot or so lower. That can create additional movement and stress on the trailer frame. A cushioned model such as # CAB-C5G will help if you are interested.
