04 silverado suspension

[painter mann]

i have an 2004 silverado, extended cab, 2 wd. v-6, it has smooth ride suspension.

 

i also have well built ( probably heavy ) adrian steel ladder rack & tool box,

 

truck paper work says 5000 lb. pulling capacity. even with light trailer truck squats,

 

( what i consider too much )

 

my question is: what should i do to prevent ruining smooth ride suspension?

 

what product wil prevent squatting & bouncing with moderate load.

 

thanks, ron

Some Firestone airbags should do the job just fine.
