Q: How much weight will my F250 be able to support with these springs?

Installed these about a month ago on my 2000 model F250SD. Install was a snap and truck rides like it did 200,000 miles ago! Would definitely recommend these springs, and the crew at SDTruck are the best!

These made my Excursion ride allot better than the worn out factory ones, the only problem is that the front is now about 3/4 of an inch higher than the rear but I believe that the rear is worn out as well. Great product.

Great value, fit right in and really improved the ride from the previous lift springs. Met my expectations on ride height and quality as advertised.

I replaced the worn factory springs on the front of my 2001 Excursion with these. They ride great and raised the front a full inch over where it was. They were easy to install and still look great. I would recommend them to anyone. I will be buying the matching rear springs as soon as funds allow. Great company to deal with.

Restored the ride height plus1-1.5 inches and truck rides much better since it doesn't slam the stops anymore. Only thing I can say negative is that the springs squeaked a little for about 6 months, they're quiet now.
