I'm adding an additional 300 pounds to the ass end of Bertha with a Dissent rear bumper and spare tire. She already sags more than I would like when hooked up to the camper. Does anyone offer heavy duty springs that can handle the additional weight?

Get Dobinsons springs, C59-817V which handles 175 - 330 lbs, C59-819V which handles 550 - 770 lbs. These are constant rear weight. Alternatively, you can get Icon dual rate spring kit. I had this before switching to Dobinsons because I added more weight.

I would suggest going with Dobinsons if you intend to tow the camper. Dobinsons are discounted by 15% so good time to get them. Check out this website, Exit Offroad are the Dobinsons Suspension Experts in the USA, for more info. Mike at ExitOffroad is really helpful.

Matt at LC250Mods can help as well.
