Hellwig25300 LP Mounting Hardware Kit for the Hellwig Load Pro (LP) Helper Springs

I bought Hellwig 9510 LP-25 for an E350 box van, and Hellwig 984 for an F150. Two hours and 35 minutes after opening the boxes, my son and I had both kits installed. I had a fork lift to raise the rear ends, and a large c-clamp came in handy.The first hardware kit I recieved for the 9510 was wrong size, but that was my damn fault for not measuring the width of the leaf spring first. The return was easy, and the refund was prompt.Son reports a much more stable ride in the box van. My F150 now rides like a pickup used to ride...(like a truck. lol) And it's a world of difference dragging a trailer around. The no load height increased about 1 1/2 inches.I am NOT treating it like an F250, but it acts like one.Buy these products with confidence.AND MEASURE YOUR SPRING FIRST!!!Oh, and I really wanted blue springs. lol (they have a nice industrial grey finish)

These springs work. I cannot measure tongue load easily, but I can say I pulled a 30 foot gooseneck stacked 7 high with hay with a 1988 F250 Super Duty and it just set level, maybe a skeech down in the rear. It was about 250 bales, not quite a load at the rear. The trailer plus hay would have been something close to 18,000 lbs. Why didn't I stop at the scales and check? DUH. 300 bales would have squared off the load. They do kinda make the truck ride like a Missouri mule. But if you want a Tennessee Walker ride, don't put overload springs on the truck! The truck does anything I need it too, and it handles good under load now. in 1988 the F250 would have been a single rear wheel F350. So it's a heck of a truck to start with. I'm going to guess that the tongue load was well over 2 tons. I don't need the 3500 springs.

Springs very good, but missing nuts for main u bolts cost $24.00 to replace locally. Also bought e350 superduty kit, but still had to buy two longer ubolts, Cost $23.00, to fit rear leaf attachment. This same attachment location also had to be reversed to avoid hitting the rear brake calipers. Spent another $5.00 for various locknuts and washers to complete the install. Kit needs to be inspected before being shipped and maybe more detail in fitting to e 350 dually wheel model. Did stiffen the ride and brief test ride with load showed less front end float, which is what I was trying to fix. I do have it with about 2 1/2 inches of gap from helper to top main leaf, understand can go to about 1 1/2 inches of gap if needed, but the explanation of what to do here is very minimal.

Be careful when you order, said it fit my vehicle and it didn’t. I have 3” springs and first kit was for 2 1/2” spring. Easy return but second shipment was missing parts and must have been another return. The parts are strong and installation was easy.

We purchased these to help with the load of our 5th wheel. The hitch weight on this trailer is up there a bit but still within truck rating and it would push the rear down a bit, these really help with keeping it level.

Read the description carefully. It shows a picture of a complete spring plus amounts. This is not the case, its just the bolts and metal mounts. You have to buy the springs seperately and they that more than doubles the price!

Parts missing this is not what i order there is no leaf springs

Muy buena inversión gracias
