The Air Lift 57275 LoadLifter 5000 Air Spring Kit is specifically engineered for your 01-10 GM 2500HD/3500HD 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:
- Improved braking and steering: when all four tires are firmly on the ground, braking time and steering are both improved.
- Less sway: Air springs increase spring rate and vastly improve vehicle stability.
- Less bottoming out: Air springs provide adjustable load support to help prevent bottoming out on rough roads.
- 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.
- Less porpoising: Even heavy pickups which dont squat when loaded can begin to porpoise vertically when towing heavy trailers. Adjustable air springs dramatically reduce this problem for a safer, more comfortable ride.
The kit includes 2 air springs, brackets, air lines, Schrader valve and all of the hardware you need for installation. LoadLifter 5000 air spring kits are engineered to be installed in under 2 hours and include a fully illustrated, user-friendly instruction manual.

10/10
Color: Multicolor-4pack-a1, Size: Small
These are some of my favorite underwear. I find myself reaching for these constantly. They're very good quality and very stretchy. I'm 140 5'3 and I got a small they fit great. Someone larger or smaller would fit in the small too. I do stress that the leg holes are a bit tight on my thighs and I don't have thick thighs at all. On someone with thicker thighs I'd say size up to a medium. You can wear these as mid/high waisted or low waisted. They're versatile! The cotton gusset is a plus too❣️

Better than Haynes at for less money
Color: Multicolor-4pack-a1, Size: XX-Large
I am surprised by the quality of these knickers. They are better than Haynes for less money and when I say they’re better, I mean far better, but I can’t believe how comfortable and STRETCHY best underwear is

love love love!!
Color: Multicolor-4pack-a1, Size: Medium
like my daily driver now, like i never thought underwear could be this good untill now! have bought 2 4packd and will probably get more in the future :) they are snug but not suffocating, with my darker skin i was worried of them getting darker in that area but so far(3-4 months) they’ve been holding up well and clean easily in the washing with a bit of stain remover!

Satisfactory
Color: Multicolor-4pack-a1, Size: X-Large
If your wanting an easy on high waisted underwear these work.
They are honestly strange material, a mix of three different things- not bad but different.
Not seamless, might ride up, slightly on the thicker side. Will last a while. Comfortable enough but not amazing.
Got for after a surgery and needed something different- these worked but would I get on a normal day probably not.

Super soft and comfortable!
I haven't bought new underwear in forever. I used to wear thongs, but now find them incredibly uncomfortable. The last few times I've tried to buy new underwear, the sizing was either way off (I'm a medium, but gave up after having to return them for a large and then extra large) or the quality was horrible (two brands stretch waaaay out and they can fall down while wearing them (I have larger ass-ets, so they shouldn't start to slide down during use). I tried these after buying some bamboo pyjamas and I love them! They are incredibly soft, comfortable, and stretchy. I can use them all day, and they work well, whether I'm lounging on the couch or wearing them under my spandex shorts at the gym, they don't ride up or slide down. They are both comfortable and look sexy, while providing support in all the right places. I haven't had them too long, so I can't speak on the durability, but they appear to be of good quality and I plan to order more, this time without the band.
