| Product Descriptions | All the limited slip differentials in the GT L.S.D. Series were tested in actual battle in All Japan Grand Touring Championships. They were used during the 2002 season by the GT500 XANAVI NISMO GT-R and the GT300 Daishin Advan Silvia.They are currently favorites at the D1 Grand Prix, at tuning car races and at touring car endurance races such as the Super Taikyu. From street racing to circuit and drifting, you'll find an LSD to fit your needs here. Basic Model: Fixed initial torque & internal pressureThe design standard for the initial torque output value is 8.0 kgf・m at the time of delivery. After the LSD is broken in and the plates are working well together, it will stabilize at 6.0 to 6.5 kgf・m. 20 large-diameter plates Increasing the number of plates to 20 makes the shift from slip to lock dramatically smoother. The diameter of the plates themselves, which are the actual slipping faces of the LSD, was augmented 55% over existing models. The result is a decreased load on each sliding face for a 30% gain in durability. Plate tooth design: the greatest tooth surface for the hightest power efficiency The plates have 16 outside teeth which pick up the power input from the engine and eight interior teeth handle input from the road. The case and side gear, which catch and hold the plate gears, have been set with ultimate precision, giving you a large-diameter-plate LSD that completely controls slip judder. You will get stable, smooth, effective power and improved durability. Possibility of conversion between 2-WAY & 1.5-WAY Both 2-WAY and 1.5-WAY setups are available for purchase. By machining the pressure ring's cam angles, it is possible to convert between 2-WAY & 1.5-WAY after purchase (this will also require a unit overhaul). *With the 2-WAY, the LSD is effective whether accelerating or not. *With a 1.5-WAY, the LSD is effective only during acceleration. *For R35, 1.5-WAY is not recommended due to its vehicle characteristics. Special treatment for highest-quality plates A special heat treatment developed exclusively by NISMO is applied to all of the plate surfaces. This finish eliminates catching during slippage and ensures a smooth, linear operation. It keeps the plates working in harmony when they are first broken in, guarding against plate scorching as well as any loss of initial torque. High level of control The GT L.S.D. brings you more than just strength and efficiency. It also reduces power loss from occurring during time trials and provides the solid traction needed to attain higher cornering speeds. All of this will give you better angle control when drifting. , Application: All cars, Diff type (axle): R200 R200V, Final ratio: 4.083 |

| Remark | Please be sure to install the LSD. Please make sure that the engine and transaxle of the current car are not changed, please order. As a general rule, special processing is unnecessary at installation (JAF numbered vehicle, N1 race vehicle regulation conformity) Unless otherwise noted, please use Nissan genuine parts with ring gear bolts and side flanges installed as standard. When installing LSD, we recommend that you replace ring gear bolts, side bearings, oil seals, gaskets, etc. with new ones. In the case of L. S. D. that comes with a mounting kit, please use that. L.S.D. After installation, cornering characteristic. Considerably change does therefore please note. In order to attach good parts around each part and each plate inside the L.SD, after mounting, traveling at an unreasonable speed at an urban area or a winding road (in case of a car with a number) of 500 to 600 km, Please do "break in". Also, please be sure to change the differential oil after "break in" (at least 200 - 300 km please go). NISMO L.S.D. has a high initial torque setting (the lock ratio is high), so dragging noise of driving wheels and chattering noise inside the differential will occur during normal cornering on high road surface. Please use NISMO COMPETITION OIL type 2189E (75W 140) (Rear L.S.D. product number: KLD75-RS421) to prevent these abnormal noise and deterioration of each plate kind. 9 If each plate wears and the L. S. D. function deteriorates, replace the deteriorated plate with a new one with an overhaul disk kit and adjust it to the standard initial torque. However, it may not be possible to adjust to the standard initial torque due to wear of the differential case and the pressure ring.10 If the initial torque is significantly increased from the standard value, it will lead to breakage of power train system parts and deterioration of handling, so please use the standard initial torque for vehicles that mainly drive general public roads. |

Better than our actual mattress!!
Style: 22", Color: Grey, Size: Queen, Style: 22", Color: Grey, Size: Queen
Purchased for company to stay with us in our apartment. I honestly had no idea they made air mattresses this tall until I saw a friend with one!
My husband and I tested it out last night. We were both really impressed!
1. Really easy to inflate! First time having an internal air pump. No more forgetting the pump! The motor wasn’t nearly as loud as our previous air pump! I was able to talk to my husband and he could still hear me over the pump running.
2. Really comfortable and supportive! We chose not to inflate it fully so it contoured to our bodies better. We slept on the mattress with no sheets and I wasn’t able to feel the creases in the top which was nice. No issues with sagging and we both didn’t wake up smooshed in the middle. My husband got up in the middle of the night and I didn’t notice. So movement of the mattress is minimal! Easy to get on and off with the 22” height.
3. Easy to deflate! We followed the instructions for folding and we got it in the storage bag with no issues. Just make sure all of the air is out before you fold it.
4. High quality! We had both of our small dogs on this with us. I was afraid of their nails poking a hole but so far so good! Only a little bit of air leaked out but it could’ve been the material stretching out during the night.
Cons: The pump does not shut off automatically when inflating or deflating. So keep an eye on it so it doesn’t overfill. The mattress does get cold at night. My husband and I both mentioned that in the morning. I had to roll up in my blanket to stay warm. I’ll try sheets on next time. In the summer it might not be that big of an issue. Ours came with one patch. Hopefully we won’t need to use it.

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.
