Shocks, drop axel, depending on the actual weight of the trailer, lower psi in tires
Springs can also be designed to be softer. Is go with 5-6 leafs vs 4 with the same overall thickness.
Not sure of tire size. Example, if you have 235-85-16 10 ply tires, go to a 245-75-16 tire. About 1/2" smaller rsdious,, but carry the same wieght per tire. If you're using a 15" rsdious tire, there might be a smaller diam one, or ene a 14" that will carry 2500 or so lbs per.
More than on way to skin said cat issue.
