Over time, standard gear oil loses its specialized friction characteristics, causing the internal clutch discs to grab and stick violently instead of sliding smoothly. This stick-slip action creates a highly noticeable chatter, shudder, or low-pitched groaning noise whenever you make sharp turns from a dead stop or maneuver into parking spaces.\u003c\/p\u003e\n\u003cp data-path-to-node=\"12\"\u003eThis original equipment manufacturer (OEM) additive serves as a highly specialized fluid enhancer. Sourcing a genuine Spicer fluid formulation guarantees exact chemical compatibility with factory clutch friction materials, preventing premature disc glaze and protecting the internal spider gears from thermal breakdown. Adding this fluid treatment lowers internal operating temperatures and dampens stick-slip harmonics without causing the differential to lose its core power-splitting traction capabilities.\u003c\/p\u003e\n\u003cp data-path-to-node=\"13\"\u003e\u003cb data-path-to-node=\"13\" data-index-in-node=\"0\"\u003eProduct Highlights:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul data-path-to-node=\"14\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"14,0,0\"\u003e\u003cb data-path-to-node=\"14,0,0\" data-index-in-node=\"0\"\u003eGenuine Spicer OEM Formulation:\u003c\/b\u003e Engineered by the original axle manufacturer to ensure exact chemical harmony with factory Trac-Lok and Power-Lok clutch friction linings.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"14,1,0\"\u003e\u003cb data-path-to-node=\"14,1,0\" data-index-in-node=\"0\"\u003eEliminates Differential Chatter:\u003c\/b\u003e Modifies fluid friction thresholds to stop aggressive stick-slip shuddering and popping noises during tight turning maneuvers.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"14,2,0\"\u003e\u003cb data-path-to-node=\"14,2,0\" data-index-in-node=\"0\"\u003eExtends Clutch Pack Life:\u003c\/b\u003e Prevents hot-spot glazing on the internal metal and composite discs, preserving your differential's long-term torque bias profile.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"14,3,0\"\u003e\u003cb data-path-to-node=\"14,3,0\" data-index-in-node=\"0\"\u003eUniversal Application:\u003c\/b\u003e Formulated to safely enhance any high-quality mineral or synthetic gear oil setup requiring a limited-slip (LS) additive.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-path-to-node=\"15\"\u003e\u003cb data-path-to-node=\"15\" data-index-in-node=\"0\"\u003eApplication \u0026amp; Fluid Guidelines:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul data-path-to-node=\"16\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"16,0,0\"\u003e\u003cb data-path-to-node=\"16,0,0\" data-index-in-node=\"0\"\u003eDifferential Profiles:\u003c\/b\u003e Fits all \u003cb data-path-to-node=\"16,0,0\" data-index-in-node=\"32\"\u003eDana 30, Dana 35, Dana 44, Dana 60, Dana 70, and Dana 80\u003c\/b\u003e rear or front housings equipped with clutch-driven limited-slip carriers.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"16,1,0\"\u003e\u003cb data-path-to-node=\"16,1,0\" data-index-in-node=\"0\"\u003eUsage Instructions:\u003c\/b\u003e Shake well before using.
