Net-forged internal gears add strength, and the clutch preload is tunable by swapping spring packs so bias can be dialed in for the application. It operates automatically and smoothly. This unit is built for the GM 8.875in 12-bolt car axle.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Posi Clutch-Type Limited-Slip Differential\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAxle:\u003c\/strong\u003e GM 8.875in 12-bolt car\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRing gear diameter:\u003c\/strong\u003e 8.875in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAxle shaft diameter:\u003c\/strong\u003e 1.29in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpline count:\u003c\/strong\u003e 30\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGear ratio:\u003c\/strong\u003e 3.08-3.90\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRebuildable:\u003c\/strong\u003e yes, carbon clutch discs with tunable spring-pack preload\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart number:\u003c\/strong\u003e 19554-010\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eAxle Fitment\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFits the GM 8.875in 12-bolt car with 30-spline axle shafts (ring gear 8.875in, axle shaft diameter 1.29in), covering 1964-1972 GM 12-bolt car applications at 3.08-3.90 ratios.
