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

Very good
I really liked this teeth whitening kit. It comes very complete with an LED light, whitening gel pens, and a shade guide to track your progress. The instructions are easy to follow, and the design is practical and comfortable to use. After several uses, I noticed my teeth looked a bit brighter and cleaner. I also like that the device is rechargeable, which makes it convenient and easy to use anywhere. Overall, it’s a great option for at-home teeth whitening.

Must have!
I am honestly blown away by the Puur Smile Teeth Whitening Kit — it’s become a must-have in my self-care routine! From the moment I started using it, I noticed a visible difference in the brightness of my teeth. Even stubborn stains from coffee and wine have faded noticeably after just a few sessions.
The kit is super easy to use, and the instructions are clear and straightforward — no fuss, no mess. I love that it doesn’t cause sensitivity like other whitening products I’ve tried in the past. The LED light feels gentle, and the gel goes on smoothly without irritation.
My smile looks brighter, cleaner, and more confident — and I’ve already gotten compliments from friends and coworkers! The results feel professional quality but at a fraction of the cost.
If you’re looking for a reliable, effective, and gentle whitening system, this kit is a total winner. Highly recommend! 😁✨

Ready, Set, Smile
So far I’m impressed! I’m anxious to see the results after more time. It’s easy to use and it seems much more professional than others I’ve tried.

Haven't seen an extreme difference
This looks to work about as good as any other teeth whitening product out there. It has the whole mouth piece with the light, i can't say is actually doing anything special. The real magic seems to be whatever is in the tubes, but the stuff only works about as well as any other whitening strip i've ever used. You'll get a few shades whiter, but nothing absolutely crazy. I think for the trouble of applying and then wearing the mouth piece to throw the light on to get the whole thing going, i'd rather just use burst white strips or something similar.
