{"product_id":"posi-limited-slip-differential-8-875-inch-ring-gear","title":"Posi Limited-Slip Differential 8.875-Inch Ring Gear","description":"The Eaton Posi limited-slip differential (LSD) is engineered for GM Chevy 12-bolt car rear axles, offering enhanced traction control for various applications. When torque increases, these clutch packs grab effectively, transferring power to the wheel with superior grip for improved stability and control.\n\nThis differential is built with precision-forged gears and features a clutch-type design for automatic and rebuildable operation. It is compatible with 3.08 to 3.90 gear ratios and requires an 8.875-inch ring gear size. Key specifications include a 30-spline count and a 1.29-inch axle shaft diameter, with a 12-bolt cover configuration. The notes specify fitment for automatic transmissions in the muscle car era (1964-1972), including models like Bel Air, Biscayne, Camaro, Caprice, Chevelle, Malibu, El Camino, GTO, Impala, and Monte Carlo.\n\nFor optimal performance and longevity, it is recommended to use a quality, petroleum-mineral based GL5 lubricant. Package deals are available that may include OE or aftermarket ring and pinion gear sets, as well as Timken or Koyo master bearing installation kits. Consult the Eaton\/Detroit Differentials application catalog for further details and specific fitment information.","brand":"Eaton","offers":[{"title":"Default Title","offer_id":52687911551288,"sku":"19554-010K3","price":750.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/663682278.jpg?v=1784887231","url":"https:\/\/store.motormia.co\/products\/posi-limited-slip-differential-8-875-inch-ring-gear","provider":"MOTORMIA","version":"1.0","type":"link"}
