The Air Lift 57399 LoadLifter 5000 Helper Spring Kit is specifically engineered for the rear of your Ford F-250/350/450 4WD Pickup while towing and hauling your heaviest loads with full-time load support. These tough, durable air springs provide up to 5,000 pounds of leveling capacity and are fully adjustable to keep your vehicle riding stable, level and comfortable whether loaded or unloaded.Air Lift adjustable air springs work with your existing suspension to give your vehicle more leveling support when you need it, so your vehicle is always level and stable. Proper weight distribution to all tires means more safety and a more comfortable ride as well. This results in:
- Less sway: Air springs increase spring rate and vastly improve vehicle stability.
- Headlight aim: Only level and stable vehicles provide safe and proper headlight aiming.
- More even tire wear: when weight is evenly distributed to all four tires, tires wear more evenly.
- heavy trailers. Adjustable air springs dramatically reduce this problem for a safer, more comfortable ride.
- Less bottoming out: Air springs provide adjustable load support to help prevent bottoming out on rough roads.
- Less proposing: Even heavy pickups which don't squat when loaded can begin to porpoise vertically when towing
- Improved braking and steering: when all four tires are firmly on the ground, braking time and steering are both improved.
Features:
- Up To 5,000lbs Of Leveling Capacity
- Air Adjustable From 5 To 100 PSI
- Includes Roll Plates To Protect The Air Springs
- Quick Connecting, Easy-To-Use Air Fittings
- Built Like A Tire & Reinforced w/ 2-Ply Fabric For Maximum Strength

My experience with the Anker Products is Great.
Style: 7 in 1 【1 HDMI】
Anker USB C Hub (7-in-1)
I now have several Anker Products in my home. These folks just know how to build products. Affordable and durable, stable and easy to use. This 7 in 1 is all Plug and Play. I am using an external power supply, and this product delivers it to all of my connected devices.
The stability of every thing plugged into the USB Ports keeps everything connected just as it should.
I recommend the Anker Product Line and this product in particular.
SO, if you're in need of additional USB Ports, go with Anker.

It's a job but totally worth it
Size: 36 sqft
Pack a lunch when you tackle this project boys.. its a doozy!! Month in going great so far definetly did what I purchased it to do. 2000 chevy with two p3 10s every bass drop sounded like an old firebird with loose trunk bolts. Threw this on the back walls floor underneath the speaker and the doors.. all that energy is now in the cab with me instead of getting lost in rattling metal!! Love it!!! Left a few pieces outside after I was done rained like hell on them so water doesnt hurt this stuff at all or direct sunlight in south mississippi.. good stuff pick this up and make them systems thud instead of rattle!!! You wont regret it!! I didn't!!

This works very well to put down road noise. The difference was immediate in my van. I was shocked it made such a difference.

Reasonably priced sound deadening
Size: 18 sqft
Easy to cut with a carpet knife. I used a heatgun to make it stickier and more moldable. The foil isn't so thick that you risk cutting yourself like some Dynamat variants.
