{"product_id":"rear-diff-rear-bushings","title":"Rear Diff Rear Bushings","description":"The Powerflex rear diff rear bushings are engineered to replace the factory differential bushings on BMW E46 M3 (1999-2005) and E85\/E86 Z4M (2003-2008) models.\n\nPowerflex utilizes advanced manufacturing techniques and standardized durometer levels specific to each fitment and location to ensure optimal material hardness. Each bushing set includes specialized copper-based grease, and the material design features built-in lubrication reservoirs, which significantly reduces the need for future re-lubrication. This kit is covered by a lifetime warranty.\n\nTo ensure proper performance and longevity, these bushings are designed as a direct-fit upgrade. Compatibility is specifically limited to the E46 M3 and Z4M chassis. For all other BMW 3 Series or Z4 configurations, please verify specific part number compatibility, as fitment requirements can vary by chassis code.","brand":"Powerflex","offers":[{"title":"Default Title","offer_id":52663311171896,"sku":"PFR5-4620Bx2","price":147.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687527054.png?v=1784325831","url":"https:\/\/store.motormia.co\/products\/rear-diff-rear-bushings","provider":"MOTORMIA","version":"1.0","type":"link"}
