Kryptonite Stage 3 Leveling Kit With FOX 2.5 HTO Shocks 20-26 GM 2500HD/3500If you're ready to level out the stance of your Duramax L5P and want the strength and ride quality to match, the Kryptonite Stage 3 Leveling Kit with FOX 2. 5 Performance Series shocks is a serious upgrade for daily drivers, weekend warriors, and workhorses alike. Whether you're clearing room for 34" tires, eliminating that nose down factory rake, or just want a stronger, smoother ride, this kit delivers in every way. At the heart of the system are
If you're ready to level out the stance of your Duramax L5P and want the strength and ride quality to match, the Kryptonite Stage 3 Leveling Kit with FOX 2.5 Performance Series shocks is a serious upgrade for daily drivers, weekend warriors, and workhorses alike. Whether you're clearing room for 34" tires, eliminating that nose-down factory rake, or just want a stronger, smoother ride, this kit delivers in every way.
At the heart of the system are Kryptonite’s forged torsion keys. These keys are designed to grab the hex surface of the torsion bar with a tighter, sturdier fit and provide up to 2" of lift without adding pressure to your stock suspension components. Built 25% stronger than factory and corrosion-resistant, they’re built to last for the life of your truck. Complementing the keys are Kryptonite’s boxed upper control arms, laser cut, expertly welded, and proudly made in the USA. These UCAs improve alignment, strength, and suspension travel whether you’re stock height, leveled, or lifted.
The Stage 3 kit steps it up further with FOX Performance Series 2.5 HTO (Hydraulic Top Out) shocks. These aluminum-body shocks are precision-tuned with internal floating piston technology, which separates oil from the high-pressure gas chamber to eliminate aeration and ensure maximum damping performance. They’re designed to give you a comfortable, controlled ride on the road while holding their own through rough terrain, towing loads, or hauling gear.
For those operating in harsh climates or dealing with worn-out factory hardware, the optional Kryptonite cam bolt kit is a smart add-on. It’s especially recommended for high-mileage trucks and allows proper front-end alignment, as long as your upper control arms remain in the stock location. Also available is the alignment pin kit, which replaces bent or crushed factory pins and simplifies the alignment process. This set makes it easier to dial in your suspension geometry after the lift is installed.
Whether you’re after better handling, more clearance, or just want to upgrade tired factory components, the Kryptonite Stage 3 Leveling Kit with FOX shocks brings the ride, the reliability, and the rugged performance you need.

Great for the entire family but expensive
So far so good. The brand of boxers we had been buying changed their style and construction so we needed to find an alternative. These have held up well so far to multiple weeks of frequent washing and wearing from the entire family. We did size up from the usual 6/M we normally buy and ordered large to prevent the legs from rolling up which worked out great. Our daughter likes the length and how soft the fabric is for wearing under skirts and gym shorts and liners stay put without moving or leaking as another reviewer mentioned. Our son says they are comfortable and fit well being just supportive enough without being constrictive. We all agree that there seems to be not enough fabric in the back as they tend to be much tighter across the backside than the front and that also causes the waist band to ride lower in the back than the front. These have better seam placement than some brands we tried with no seam across the lady bits and no seam down the middle of the back side so they are more much comfortable but the cost is also much higher and that is why we're only giving it 4 stars. These will stay in the rotation until we find something cheaper that both us and the kids like.

Pregnant lady review! Soft, comfortable, cool.
Color: 03-multicolour (4-pack), Size: Large
So soft, comfortable and cool. I'm pregnant and I've gained weight in my legs. I love wearing dresses but my thighs were rubbing together too much. These are perfect to wear under dresses. I also wear them under my bibs at work and it keeps me from getting overheated but I don't have to worry about whether or not my underwear show since they just look like shorts. I wish these came in maternity. I just keep them below my belly. I'll be buying more for sure.

I want to live in these
Color: 01-multicolour (4-pack), Size: Medium
I bought 4 different sets of new underwear. Unfortunately these came last. It’s unfortunate, because if they had come first I would have cancelled all my other orders or returned them and ordered more of these. I never want to wear anything else ever again; these are the comfiest undies I’ve ever owned, I want to live in them. I can wear them under pretty much anything except leggings or very tight pants (but let’s be honest, I don’t wear those anyway.)
They are incredibly soft and breathable, they wash well, don’t roll, keep my thighs from rubbing, are comfy to sleep in, and the colors were true to the photo.
Just a heads up, they are on the thin side and just a bit see through in the rear.
I’m 5’5” 140lbs and the mediums fit perfectly, they go about mid-thigh.

Extremely comfortable
Color: 02-multicolour (4-pack), Size: X-Large
These are by far the softest and most comfortable underwear I have ever owned. The leg portion absolutely does roll up as so many others have mentioned, however, I did not find that to be uncomfortable at all just annoying that they don’t stay in place.
I bought these specific underwear to see if it would help alleviate HS symptoms at all. They have definitely helped with wicking moisture away from the skin. More time will tell if it’s truly helpful for HS. For now, I will recommend these. They are thin, breathable, butter soft, wick moisture comfortable and I would buy again…maybe in a different style next time. I have washed them several times and they seem to be holding up rather well so that is also of supreme importance given the cost of the item.
Again, I would recommend this item and plan on purchasing more in a different style very soon.

Eaten by my Thighs
Color: 04-multicolour (4-pack), Size: X-Large
I wanted to love them. Sadly they have let me down.
Pros: natural breathable fabric , super soft and comfortable, cotton panty gussets for feminine health and panty liners will stick!! Yay:). And the colors! They are great!
But here’s the Con. And it’s the con of all cons.
THEY RIDE UP!! Eaten by my thighs. I’m 5’6” and in the general area of 175. I fluctuate depending on how many times I visit the bakery! :) I don’t have a thigh gap but it is not a super tight thigh squeeze. I seldom have thigh climb but these do. I tried two different sizes to see if that made a difference. Nope.
I was miserable at a recent theme park in these. I was wearing long heavy dresses and it was quite awkward to yank these legs down non stop.
They feel amazing and they have all the requirements
1. Soft
2. Comfortable and stretches with you
3. Breathable with nice thin fabric. Not bulky
4. Natural fibers
5. Great colors
If you are a person that is not blessed with Thunder Thighs, please order these. They are great! I wear them at home and to locations that I will not be doing a lot of walking at. I have washed them so many times and they look like new still.
