{"product_id":"gm-9-25-ring-and-pinion-gear-set-4-11-ratio","title":"GM 9.25\" Ring and Pinion Gear Set 4.11 Ratio","description":"The USA Standard Gear ZG GM9.25-411R is a high-performance ring and pinion gear set engineered for GM 9.25\" front differentials with reverse rotation. The 4.11 ratio helps the engine deliver more power to the ground while reducing stress on the powertrain.\n\nConstructed with strong, high-performance quality and designed using state-of-the-art software, these gears undergo rigorous in-house quality evaluation to ensure they meet dimensional, material, and fitment testing standards. Key specifications include a 9.25-inch ring gear diameter, a 30-spline pinion, 12 ring gear bolts, and the 4.11 ratio.\n\nInstallation of new gears in an axle generally requires common hand tools, along with a hydraulic press and dial indicator for correct setup. It is also recommended to purchase a master overhaul kit, which typically includes new bearings, seals, shims, and a pinion crush sleeve. These components are essential for ensuring reliable and quiet operation for years to come.\n\nUSA Standard backs its ring and pinion gears with a one-year warranty against manufacturer defects.","brand":"USA Standard Gear","offers":[{"title":"Default Title","offer_id":52870582042936,"sku":"ZG GM9.25-411R","price":333.89,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/gm-9-25-ring-and-pinion-gear-set-4-11-ratio","provider":"MOTORMIA","version":"1.0","type":"link"}
