I have a 16' 3.5 EB with max tow package. I currently have a Bedslide, Leer top, and a bed full of tools.... Looking to stiffen the rear up a bit. Also tow boats pretty frequently as well with that payload.

Can I install some HDPP rear springs, or are they dimensionally different than the Max Tow rear springs I currently have? Trying to keep it simple and stay away from air bags if it all possible.

Any other suggestions?

The difference in a 2013 HDPP and max tow spring raring is only a 500 lbs difference. It would be cheaper to add a leaf or timbrens. On my HDPP I added timbrens this time around. Previous truck I used supersprings the leaf type.

On my HDPP I installed an add-a-leaf and Timbrens.

I have a Roadmaster setup on mine. I's already an HDPP, so it's pretty stiff. They should work well on your non-HDPP.
