Cam feeling correction for a variety of engine and use.

SLIDE CAM-PULLEY

Reviewing the material and design has allowed for a stronger and lighter unit.

Highly durable and lightweight pulley

Using a super light duralumin (A2014) as its main material that the strength has increased by 50% and hardness by 30% (over previous version). This change in material has allowed the design change that has also allowed the unit to be substantially lighter (10% less load on RB engines) and increasing the engine reliability and power.

Nickel plating increases anti-frictional properties

Gear section is nickel plated for surface hardness increase (Hv: 350 ? 500 (compared to older version)) to withstand strengthened timing belts and any foreign objects that may get caught between the gear and belt.

Accurate valve timing control (angle adjustable)

As cam duration and other engine specifications changes, the ideal valve timing point will also change. As both intake and exhaust cam duration increase, the overlap amounts can be adjusted for optimum performance. All HKS Camshafts come with recommended valve timing which can be achieved by using these sprockets in conjunction with HKS camshafts. These sprockets are compatible with standard camshafts.

(Note: Please ensure that when using these sprockets, timing chain cover must be installed.)

A lot of comfort for a very inexpensive price
Style: 18", Color: Grey, Size: Twin
We needed a spare mattress, but didn’t want to have a dedicated spare bedroom but wanted a comfortable bed. Couldn’t afford these high priced mattresses these days like the air beds or luxury coil spring with gel which are thousands of dollars. Miss air mattresses, very comfortable and adorable and I like the flocked top on it. And it has the self inflatable pump which is very easy and inconvenient.This makes a very inexpensive alternative. Even if it only lasts 6 months or so you can buy a whole lot of these for a lot less money than thousands of dollars for the other beds. In tax is a wonderful brand. I’ve bought it many times. Their vinyl material is very thick and durable. Intex makes flotation devices, blowup rafts, beach floaties, Kayaks, etc. They have an excellent product & know what they’re doing.

Great Queen Size Air Mattress - NO Fuss
Style: 18", Color: Grey, Size: Queen
Great air mattress! Comfortable to sleep on. Powerful pump. Nice size. The bag to store it is very convenient and one of the easiest to put bed in once deflated. Reviews spot on with this product.

Skeptical at first, but after first use (so far) it’s a solid product
Style: 22", Color: Grey, Size: Queen
I initially bought this to stay at my MIL’s senior community (to help her get settled), so I didn’t want to spend a lot of money on it and I planned to leave it for other relatives that might want to visit. I expected it to be cheap-ish quality and probably not last through my two week stay. First off, set up was a breeze. I laid it out and started inflation and it took about 4-5 minutes to fully inflate. The motor made noise, but it’s to be expected from something like this—I can say that it wasn’t as noisy as our Costco-bought mattress. Second, it’s big—but that’s not a bad thing as much as I thought anyway after I saw it fully inflated. Turns out, for me, it’s a good thing. Our Costco mattress sits low to the floor and as it deflates a bit during the night, it’s tough to get up. This one (the 22” model and the largest one at this writing) is wonderful as I can sit on the edge of it and stand up easily. Your experience may be different, but for older folks it makes it really easy to get out of bed in the morning. How does it sleep? Well, since I was visiting by myself and my significant other wasn’t with me, I can only speak for a single sleeper. It was really comfortable! It did take a bit of tweaking though as I thought I would like it more firm as I like to side sleep. The first couple of nights were a bit rough as I tossed and turned a bit in my sleep—I found that I couldn’t get comfortable on my side. For the reviews that say that it deflates after sleeping on it, I can say that it did seem to lose some air after the first two nights. The manufacturer does state that it does “stretch” and not deflate. As I wanted to test that statement, I didn’t change the firmness of it by re-inflating it to where I had it. The third and fourth nights were better sleep and I didn’t feel like the mattress deflated at all, so I found the stretch statement to be valid—it wasn’t losing air. After that night, I re-inflated it to where I thought I’d like it. The next night was the same tossing and turning that I had those first two nights, so I concluded that I needed to make it less firm and I actually DEflated it a bit and for the rest of the stay it was perfect! I didn’t have to touch it and I even unplugged it. When I was getting ready to leave, I started the deflation process by turning the dial in the opposite direction. It took longer to deflate, so I walked away for a bit—I’d guess about 7-8 minutes. When I came back the mattress was flat as a pancake and ready to fold. This is the only hassle of the process as folding it to get it into the storage bag and back into the box (for storage). I do like the tote that they provide as the handles make it easy to lug about. So, the first use was a success. If repeated uses reveal issues, I’ll report back. I will say that I plan to buy another one to replace our beloved Costco air mattress—she’s showing her age and the height of this one as well as the cost make it a no-brainer to get it as a second. We’ll use this one until it dies (if it even does) and then fall back on our old one if needed. I gave an overall 5 stars for the product with 4 stars for sleep quality and comfort only because your idea of these two might be a bit of a learning experience until you find your inflation sweet spot—so it’s not just an “inflate fully and use” type of scenario.

Comfortable, high-rise air mattress with built-in pump
Style: 22", Color: Grey, Size: Queen
The Intex Dura-Beam 22-inch Queen air mattress is one of the better inflatable beds I've used. The built-in pump is very convenient — no need for an external pump or battery-powered inflator. It inflates to full firmness in a few minutes and deflates just as quickly. The 22-inch height makes it easy to get in and out of, similar to a regular bed height. The plush comfort top adds a softer surface feel. The 600 lb weight capacity is reassuring for heavier users or couples. I've had guests sleep on this for multiple nights and they reported sleeping well. It held air overnight without significant deflation. My only note is to store it carefully to avoid punctures from sharp objects. Overall a great value for guests or camping.

Very good

I recently purchased this inflatable mattress from Amazon, and I’m honestly very impressed with the quality and comfort. It inflated quickly and was very easy to set up. The material feels durable and strong, and the mattress stayed fully inflated throughout the entire night without losing a
