{"product_id":"zp-spool-differential-for-amc-model-20","title":"ZP Spool Differential for AMC Model 20","description":"The USA Standard Gear ZP FSM20-3-29 is a robust steel spool designed as a performance upgrade for AMC Model 20 differentials. This component ensures that 100% of available traction is delivered to both wheels simultaneously, regardless of surface conditions.\n\nEngineered with 29 spline axles and intended for use with 3.08 and numerically higher gear ratios, this spool is a direct fit for the AMC Model 20 axle housing. While offering maximum traction, it is important to note that this type of differential is not recommended for street-driven vehicles due to its aggressive traction characteristics. It is best suited for off-road applications, drag racing, or other performance-oriented uses where maximum grip is paramount.","brand":"USA Standard Gear","offers":[{"title":"Default Title","offer_id":52870631850296,"sku":"ZP FSM20-3-29","price":427.57,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/zp-spool-differential-for-amc-model-20","provider":"MOTORMIA","version":"1.0","type":"link"}
