Default Helper Spring Question

I've read the other posts on this and did not get an answer that matches my situation. I have an '02 Ranger Thunderbolt that I am trying to turn into a tow vehicle for my business. I believe the suspension leaf springs may be less than ideal for loads.

My suspension shop good friend installed bigger thingamajigs (forgot the name) that ensure when a heavy load is applied it has about 2 less inches before the rear axle hits the rubber pad and supports the weight. At 450 lbs of cargo, the new thingamajigs hit the rear axle. Rides OK, but I suspect I would get better results and less tear on the truck if I added helper springs. My target tongue weight is about 600 lbs.

If i add 2000 lbs helper springs would that jack my truck up when I do not have trailer or load? Summit says these are medium load and ones with a rating of 1500 lbs are heavy load. I do not understand that math.

I think all I need is to get another 400 lbs of support to stop the axle from bottoming out and still allow me to carry some supplies in the truck bed.

If you wanna put that much weight in the bed spend $300 and put air bags in the rear. You can blow them up to hold the weight.

I'd rather not put air bags. I just spent $1500 adding new shocks, all new bushings, bearings, ball joints, and tie rod ends. Looking for an inexpensive fix for now.

Yeah you can put helper springs in the ear. Your still gonna spend $150+ for them. Get the heaviest ones you can if your gonna tow all the time. Your leaf springs will be worn out in no time if you don't.

Thanks Casey. With my thingamajig cushion that does not allow the truck to go too low on load I get about 2 inches more travel but bottom out at 450 lbs. As I understand it, leaf springs offer more weight support the farther they are compressed, so I suspect I am not getting the full support from my stock ones because the do not compress all the way.

If it only plan to have a tongue weight + cargo load of max 900 lbs and I already have 450 lbs support it seems obvious a 500 lbs helper is too little. I am wrestling with if I need a 1000 lbs helper or a 1500 lbs helper. Would 1500 be too much?

I went from 1250 lb springs to 1750 lb springs and I lifted the rear a couple of inches. Not a big deal just something to be aware of.

I did same as DanTheMan16, and replaced mine with a pair of heavy-duty 1750 lb leaf springs. I'm so happy. No problem with very heavy loads now. The back end sits about 3" taller than before, rides a bit stiffer, and I really like that. Having a stronger truck never hurts. See photos at http://imgur.com/a/WpQR8

I got Helwig 2000lbs helper springs, I would say it raised the back of my truck 2 inches. I put a ton in the bed and it still has 3 inches until hitting the bump stops.
