| 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: A/T car with viscous, Diff type (axle): R200V, Final ratio: 3.916 |

| 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. |

Good dog product
Color: Pink Squeak Toy, Size: Medium
We’ve had the squeak balls for many years. The squeaker doesn’t last long with an aggressive chewer. Our dog squeaks the ball so much, she makes the ball split. We remove the squeaker and the ball continues to be used for a few years until it splits enough we throw them out. The ball has good bounce. We leave them outside all year and they have lasted thru snow and hot weather. The ball has been 2 of our dog’s favorite toy.

Extremely durable even for destructo-dogs!
Color: Orange Squeak Toy, Size: Medium
I got this for our chew-monster Bruce, a very large German Shepherd & (we think) Great Dane mix, after he repeatedly demonstrated his ability to utterly destroy the large Kong squeaky tennis balls within a matter of minutes. He LOVES some squeak, so he obsessively squeaks his toys until they're crushed. After some research on longer-lasting toys, I splurged on one of these, fully intending to guilt the dog forever if he destroyed this much more expensive toy. It's been 2 months, and this ball is not only still squeaking, but it isn't chewed or destroyed AT ALL, despite Bruce's best attempts! It's smaller than his other balls, and because it's a slicker texture, it slides out of his mouth more easily. However, it squeaks when it hits the ground, and he can entertain himself with it for long periods of time.
Pros:
- Super durable
- Squeaker is molded in so it can't come out (unlike the other toys we've bought)
- Bright orange is WAY easier to see in the grass than stained green/yellow tennis balls
- Easy to clean
Cons:
- I wish it were slightly larger, because his mouth is so big. No issues with swallowing it or anything, but if they had an XL size (like other super-large sized balls) we'd go for it. Orbee, let us know if you decide to upsize!
- It doesn't squeak quite as easily as other squeak balls, but Bruce figured out how to make it work. He sometimes will even hold it against the ground to squeak it faster.
- It doesn't squeak as loudly as the faux tennis ball kinds, but wait...that's not a bad thing. It's still loud enough for him to enjoy, without the neighborhood rioting.
Overall I can't recommend this toy enough. We feel safe letting him play with it since the squeaker can't come out, and it's paid for itself repeatedly - we were going through a 6-pack of squeaky tennis balls per week (or more!), and haven't had to buy any in the last 2 months because this ball is still in pristine condition.

Poor quality — squeaker lasts 2 minutes
Color: Blue Squeak Toy, Size: Medium
These balls used to be great quality and long lasting. Something changed about a year ago and now the quality is considerably less to include the squeaker becoming inoperable within 2 mins of play. Not sure if the raw materials or the manufacturing process changed, however the decline in quality is obvious. I do not recommend this product to anyone who has a dog that is larger than 10-15 lbs.

STROBE: Favorite Ball, durable, decent battery life
Color: Glow in the Dark Strobe Toy, Size: Medium
*Update since Outward Hound redesign: The new version doesn't seem to light up as consistently on every bounce and seems to light up in a more seizure inducing way (I'm sorry I couldn't think of a better description). The light also seems to die much faster with the new version. The inner light and batter actually popped out its encasement in one ball after about 2 months of use, only by my Golden who doesn't chew particularly forcefully on it. I did notice right away and check regularly for damage, just putting that out there as a warning. It is still by far my dog's favorite ball.
Original: This is my Golden Retriever's absolute favorite ball! Particularly the strobe light up ball but she's happy with any Planet Dog ball to the point that she looks at me for the "good ball" to fetch with if i try to have her play with a ball from a different company.
Pros: by far my dog's favorite ball
- good bounce, and good squish factor yet durable
-larger size: safe for large dogs
-lights up to see at night
-decent battery life
-rain does not affect battery
Cons:
-battery is not replaceable/ rechargeable (though I'm not sure it's an option without seriously altering the design)
-regular glow (once battery is dead) is not great
-only lights up on a bounce and shortly after that
- If your dog bites down particularly forcefully it can displace the battery which typically kills it;
if submerged in water (my dog tends to place it in her water bowl when she takes a break while fetching), it is reduces battery life, both make me worry about safety
The ball always out lasts the lifespan of the battery for the light, I'd say we average about 1 month per ball while the light works with about 1 hour of use almost everyday. The ball does hold up to some of my dog's friends that are super chewers including one that is a Cane Corso. I don't let them sit and work at chewing it but they definitely squeeze it in their mouths with a good bit of force. My girl is happy to play with the ball even once the battery dies but I prefer to have the light so I can find the ball when needed. The glow color does glow when placed under a flashlight for a few minutes first but I find it doesn't glow as well or as long as other company's glow toys. My dog has a tendency to drown it in her water bowl to keep it nearby or rinse off any dirt and that definitely shortens the battery life but using it in the rain doesn't seem to affect the battery life
I think this being my dog's favorite has to do with the good bounce and squeeze factor this ball has. I like that it's slightly bigger than a tennis ball so I'm comfortable with large dogs playing with it. It fits in the "large" chuck it ball launcher. I actually discovered this specific ball when another dog had it and my dog kept taking it instead of her other light up ball that she had played with happily for months.

Great for my pitbull, worth the price! the warranty isn’t what it seems so check their site first.
Color: Orange Squeak Toy, Size: Medium
I’ve now purchased 3 and I don’t see myself ever stopping! My 55lb Staffie (pitbull) has absolutely obliterated every ball and toy (rope, rubber, stuffed) before this one in a matter of minutes. You take your eyes off it, and the next time you’d look back it would be in pieces. Kong Xtremes and other “indestructible” toys only lasted a week, tops. He also goes nuts for anything that squeaks, so keeping him happily entertained for a while was a challenge because the second he’d chomp down on a squeaker, it’d break. He’s now had this blue squeak ball for a MONTH and it STILL SQUEAKS!! He regularly falls asleep with it still in his mouth, or tucked under his chin. That’s how obsessed he is with this thing. I would 100% recommend this to anyone who needs a seriously durable toy for their super powerful chewer as that’s been my experience! This material is super bouncy and he can bite down (unlike some rubbers, Kong/West Paw) without puncturing it somehow. It’s perfect for fetch, and floats too. He’s never had a toy last this long, so this is a welcome break for my wallet despite being a more expensive toy. I was buying a few toys every week until we tried this one!
Cons: The first two balls didn’t squeak after a few days, so maybe they’ve improved something since then. The warranty replacement process is more tedious than others like West Paw, and only replaces them ONCE. It’s also requires more force to squeak this given the nature of the material, but since it extends the life of the squeaker I’m totally fine with it.
