Your cart is empty.Supercoils are heavy duty replacement coil springs, designed to remedy sagging and overworked original equipment front and rear suspension coil springs. Supercoils have a linear/constant spring rate consistent with other coil springs. Supercoils actually replace original equipment, different from Super Springs or SumoSprings that work in conjunction with and enhance original equipment.

Installed these on my 2000 2WD Ford Excursion with the 7.3L diesel engine. They fit great. They are the exact same inspiring height as the OEM ones, when you put the trucks weight on them you end up about an inch taller than factory ride height. I’m really happy with them, but you’ll most likely need to get some adjustable camber bushings to get your alignment correct. Camber is only out of spec by 1 degree, it’s barely noticeable.

Installed on a 2000 F350 Cab and Chassis 2wd, 7.3 dually with an enclosed 9’ Reading Utility Body. Truck has 280000 plus miles on the original front springs. This vehicle is loaded with tools at all times and has spent its entire life in the construction industry. Truck had developed a very noticeable rake do to the sag of the original springs. These new springs brought up the front by 2 inches and I expect it to settle a little (1/4 to 3/8 of an inch). Having spent some time considering what spring rate to use I am happy with choosing the SSC-31 spring. I will be installing KYB mono max shocks front and rear. Ride quality greatly improved and feels like it took a lot of body roll out of it. This can really be felt when taking tight turn exit ramps. Truck currently has a slight 0/ camber but it is not excessive, there are no other alignment issues. Vehicle tracks straight on numerous different road surfaces. Vehicle will get an alignment after new shocks and a couple of hundred miles. Install took less then 2 hours using an impact gun with extensions to remove the 1-1/8 hold down bolt.

Springs are heavy duty however they did not fit on my 2015 f-250 flex fuel because the top insulated part is larger

I have an E-450 súper duty box truckMy front wheels have negative camber and both tires had severe wear in the inside to the point it has lost all the tire threats.I removed the old coil springs and measure the same length that the new ones (side to side before installation). Once installed the coils lift the suspension almost 1 1/2".and changed the position of the tire to neutralor slight positive camber.Huge difference driving the truck after installation, more stable in the turns and much better when going over speed bumps.Also the diameter of the spring rod is a little thicker.Also they were a perfect fit.Conclusion if you have the same issue than my 2006 ford E450 this are the springs you are looking for. Each spring coil from the dealer cost $360 (each)Hope this help

Bought a 2003 F250 two wheel drive with 82 k miles on it. the springs were wore out due to age and weight of the motor. I put this set on it in about 2.5 hours and WOW! what a difference it made. lifted the nose back to level a good 1.5 inches and now it floats over the bumps instead of knocking out my teeth. So happy with this purchase, installed them by myself with two jacks.

Wow! Great product and it rides better than the originals! Easier to steer as well. Raised front end 1.5â€. Originals were sagging.

Great rideRestored ride height, but coil very slightly drags upper mount on 2nd coil down. Would have given 5 stars if fit was better.
