In conclusion, while phantom has radial channel and relays only on high rated springs, our product has high rated springs to creating preload, but has dynamic lock from ramp angles as well. We use friction shims between gears and plates. From our experience in producing LSD clutch plates, we used the same materials for friction shims which gives them high resistance and longevity, so there are no metal shavings.Materials that we use in production are only top quality tool steel heat treated and nitrated to achieve the highest quality surface finish possible. That gives our product very high durability and longevity. Our products have proven themselves on many race cars on hill climb, circuit and autocross, giving the competitors up to 10 seconds better times than personal bests.
