The miniaturized snap ring (Belville washer) allows for increased disc capacity. The herringbone planetary gear design also allows for increased disc capacity as well as increased side gear strength. The patented snap ring (Belville washer) design allows for progressive, adjustable locking. The relief cut in the housing minimizes stress on the cone spring during LSD operation. The friction discs are precision machined on both sides simultaneously, to extremely tight tolerances (only two machines in Japan have this capability).\u003c\/p\u003e\n\n \u003cp data-start=\"0\" data-end=\"752\" data-is-last-node=\"\" data-is-only-node=\"\"\u003e\u003cstrong\u003eNo break-in required:\u003c\/strong\u003e The OS LSD is precision-machined to extremely high tolerances; once installed, it can be used immediately for racing.\u003cbr data-start=\"219\" data-end=\"222\"\u003e \u003cstrong\u003eNo Service Required\u003c\/strong\u003e : The LSD OS has a true 100% blocking capability and is made from high quality materials using advanced manufacturing methods to ensure extreme durability.\u003cbr data-start=\"430\" data-end=\"433\"\u003e \u003cstrong\u003eUltra-consistent performance:\u003c\/strong\u003e The design and construction of the OS LSD prevent significant component wear, ensuring consistent performance regardless of usage.

Since 100% locking capacity is not possible, the friction generated by the discs produces high levels of heat, which wears the discs down so they can seat properly together. (Lower manufacturing tolerances for the discs result in variations in shape, thickness, etc.) This type of break-in procedure can result in uneven wear between the left and right sides of the LSD.\u003c\/p\u003e\n\n\u003cp data-start=\"0\" data-end=\"286\"\u003e \u003cstrong\u003eRequired Periodic Service:\u003c\/strong\u003e Since this type of LSD cannot achieve true 100% lockup, the constant friction in the LSD components generates more heat, leading to increased wear or premature failure, necessitating periodic service of the LSD components.\u003c\/p\u003e\n\n \u003cp data-start=\"288\" data-end=\"538\"\u003e\u003cstrong\u003eInconsistent Performance\u003c\/strong\u003e : Since these LSDs already have driver-induced wear during break-in and continue to wear throughout the life of the unit, actual locking performance decreases the more the unit is used.\u003c\/p\u003e\n\n\u003cp data-start=\"540\" data-end=\"812\" data-is-last-node=\"\" data-is-only-node=\"\"\u003e \u003cstrong\u003eMore frequent fluid changes required\u003c\/strong\u003e : Due to the amount of friction generated in the LSD, additional heat is produced, which causes the differential fluid to deteriorate more quickly.

Typically, the preload is set higher to achieve greater locking capacity, but this comes at the cost of the unit locking up at lower speeds. Normal behavior is wheel hopping in turns and generating unwanted noises.\u003c\/p\u003e\n\n\u003cp data-start=\"0\" data-end=\"21\"\u003e DESIGN DIFFERENCES with \"TRADITIONAL\" clutch-type LSD\u003c\/p\u003e\n\n\u003cp data-start=\"0\" data-end=\"21\"\u003e – They usually use cast components, without heat treatment.\u003c\/p\u003e\n\n\u003cp data-start=\"0\" data-end=\"21\"\u003e – The larger pressure ring limits the space for the discs.\u003c\/p\u003e\n\n\u003cp data-start=\"0\" data-end=\"21\"\u003e – Less rigid planetary gears.\u003c\/p\u003e\n\n\u003cp data-start=\"0\" data-end=\"21\"\u003e – Lower disk capacity.\u003c\/p\u003e\n\n\u003cp data-start=\"0\" data-end=\"21\"\u003e – They do not have progressive blocking capacity.\u003c\/p\u003e\n\n\u003cp data-start=\"0\" data-end=\"21\"\u003e – Smaller surface area on the discs.\u003c\/p\u003e\n\n\u003cp data-start=\"0\" data-end=\"21\"\u003e – Discs are usually manufactured with greater manufacturing variability.\u003c\/p\u003e\n\n \u003cp data-start=\"0\" data-end=\"21\"\u003e– They do not have relief in the housing for the conical springs. \u003c\/p\u003e\n\n\n\u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n\n\u003c\/div\u003e","brand":"OS GIKEN","offers":[{"title":"Default Title","offer_id":55166862557518,"sku":null,"price":1749.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0874\/3655\/8670\/files\/osgiken210.png?v=1742292229","url":"https:\/\/afraceshop.com\/en\/products\/autoblocante-os-giken-superlock-l2-215k-215l-215lw-2-93","provider":"AF RACESHOP","version":"1.0","type":"link"}
