As torque, line pressure and shift aggression go up, that shows up as deformed cog teeth, spline wear and cracking under shock load. Spool machines this hub from billet 300M, a vacuum-melted ultra-high-strength alloy steel used in aerospace and motorsport drivelines, for higher strength, better fatigue resistance and consistent properties throughout.\u003c\/p\u003e\u003ch2\u003eFits\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eZF 8HP70 transmissions\u003c\/li\u003e\n\u003cli\u003eZF 8HP75 transmissions\u003c\/li\u003e\n\u003cli\u003eZF 8HP76 transmissions\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFeatures\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eFully CNC-machined from billet 300M alloy steel\u003c\/li\u003e\n\u003cli\u003eHigher strength and fatigue resistance than cast steel\u003c\/li\u003e\n\u003cli\u003eTight tolerances for accurate cog geometry and even load spread\u003c\/li\u003e\n\u003cli\u003eCleaner torque transfer and more consistent shifts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eGood to know\u003c\/h2\u003e\u003cp\u003eA key reliability part for any 8HP70, 8HP75 or 8HP76 build with more power, upgraded clutches or higher line pressure.
