{"product_id":"differential-locker","title":"Differential Locker","description":"It replaces the spider gears within a standard open carrier, ensuring that power is delivered to both rear wheels 100% of the time. This full-time lockup is ideal for drag racing, sled pulling, or off-road use where consistent traction is critical.\n\nConstructed as a low-cost solution for enhanced grip, this mini spool is specifically engineered for Ford 9-inch rearends with 31-spline axles. Its installation into an existing open carrier simplifies the upgrade process for enthusiasts looking to maximize power delivery.\n\nWhile providing significant traction benefits, the USA Standard Gear mini spool is explicitly not recommended for street-driven vehicles due to its full-time locking nature, which can affect steering and tire wear under normal driving conditions. For vehicles equipped with large tires or those modified for high horsepower, this type of spool is often a suitable choice when prioritizing pure traction over street manners.","brand":"USA Standard Gear","offers":[{"title":"Default Title","offer_id":52870636110136,"sku":"ZP MINSF9-31","price":54.89,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/differential-locker","provider":"MOTORMIA","version":"1.0","type":"link"}
