Suspension upgrade

Haven't pulled my travel trailer yet with the Roadmaster Active Suspension, but just driving around I have noticed a improvement with the Handling, here are some pics of the installation

 

What advantage is that over a shackle

 

Shackles are for lift, those are more for stability under load

 

my understanding of it is that is keeps the leaf spring from flatting out under load, you adjust the tension on the spring

 

Do you have any updates having had them for a few months now?

 

I haul a lot of stuff for work like half pallets of cement, brick and dowels. Basically a lot of construction material. Will this help?

 

Still glad I put them on, ride is definitely better, just using the truck as a truck it has greatly improved the ride with a load in the bed, pulling my travel trailer or pulling my side by side is a plus.
