Replacement OEM 43-1263HD Leaf Spring FAQ with SD Truck Springs

Q: I have a 2005 Ford F250, and I carry heavy loads on and off the construction site on a daily basis. What is the difference between the HD spring and the regular spring
A: Spring Capacity plays a huge factor in this decision. These HD springs offer support up to 4,400lbs whereas the regular springs only offer up to 3,000.

These springs are great! I thought the ride would be worse than it is but they are not as stiff as I thought they would be. They did add about 1 1/2" to my height so I removed the lift spacer that was there and now the trucks sits perfect. I haven't put a lot of weight on them yet but what I have put the truck doesn't drop at all. At all!! I would recommend them to anyone with a 3/4 or 1 ton pickup that needs heavy duty load capacity.

Doing great, this is just a picture to show you what these springs endure on a daily basis. I buy all my springs and suspension parts from you guys for one reason, I always get a quality product! I'll be making an order soon for a new truck I'll be adding to my fleet!

2007 F250 6.0L FX4 package. The truck had seen some abuse before I purchased it. I upgraded the suspension with these 6/1 leaf springs, paired with the HD lift coil springs and 5100 series Bilstein shocks. There was a night and day difference in the towing capability of the truck. Installation took me roughly 4 hrs on the leaf springs. Needless to say I am very satisfied with this purchase!

Hello, the front and rear leafs for my f250 are perfect. Only issue I have is I am going with a lift, and the front leafs will no longer be needed, delivery is some time slow rest all fine . Fitment went smooth, and handles my everyday work

I purchased the entire kit that included both front and rear springs. This kit included all brackets, bolts, and hardware for a successful installation. My Excursion now sits up nice and tall and the ride, while stiffer than the stock ride, is very comfortable and towing heavy trailers no longer sags the rear as it did before. I suggest ordering new shocks as I did to complete this awesome package.

Great product. Fixed the sagging in my truck. Before truck would drop 5 to 6 inches when I coupled to my camper. Now no more than a inch. Great improvement.

Everything fit as it should, i can carry heavy loads without the rear end sagging, it lifted my truck 2-3" and its just a slightly stiffer ride than the stock springs. I should have upgraded a long time ago

I just want to say that the overall service I received at SD truck Springs is wonderful and anytime I need suspension parts thus is where I'll go

I installed this 6 pack on a F250 replacing the stock 4. They lifted the truck a lot more than I wanted so I removed the bump/spacer and that brought it down to about 2" over stock. You'll need new U bolts (shorter if you take the spacer out) and I installed KYB shocks with 2" extra travel. The truck is perfect for hauling a trailer now, but I will probably level the front in the future.

This is probably the best deal on the internet for Ford Super Duty leaf springs. I use my F350 hard and the factory rear springs were busted. First thing I hauled with these new springs was a full chord of hardwood firewood. I have stake pocket racks that make it so I can get a full chord on, split and stacked, which is probably around 4,000 pounds of wood. These leaf springs squatted way less than the factory ones ever did and provided more stability with that kind of load. I highly recommend these as a replacement or upgrade from the factory 4 leaf pack

The rear springs I purchased have performed as expected. My 2002 Crew Cab 4x4 rides sturdy like a tuff truck again They were easy to install, clean swap, with the proper power tools and a helper elf. My ride and carrying capacity have improved alot. They are better than the OE VB Code springs. I have been telling everyone I know that owns a Superduty, to upgrade their weak springs with the same 6 leaf rear sprngs, and they will be pleased with the smooth responsive ride and load bearing capacity. Also, these springs restored the Sag when compared with the OE rear springs (very weak). (P.S. the ford dealer told me they stop providing support for their vehicles, after 10 years; I was disappointed).
