{"product_id":"tech-53-rear-differential-bushing","title":"TECH-53 Rear Differential Bushing","description":"The Drift HQ TECH-53 rear differential bushing is engineered to replace the weak factory unit found in BMW E46 models, which is prone to cracking and causing undue stress on the drivetrain. This upgraded bushing is constructed from durable Delrin for resilience, paired with a 6061-T6 aircraft-grade aluminum inner sleeve for strength and light weight.\n\nDesigned to last in demanding motorsports applications, the TECH-53 bushing addresses the common issue of a loud \"clunk\" under hard acceleration or when clutch kicking, a sign of a worn OEM differential bushing. Unlike aluminum bushings, the Delrin material offers a more comfortable driving experience, reportedly without introducing new vibrations into the cabin.\n\nThis rear differential bushing directly replaces the OEM part number 33176751808. For a complete renewal of differential bushings, it is recommended to pair this kit with two of Drift HQ's front diff bushings. It is explicitly noted that this bushing is not compatible with the M3 models.\n\nVehicle fitment includes: 1999-2005 E46 BMW 323i, 323ci, 325i, 325ci, 325xi, 328i, 328ci, 330i, 330ci, 330xi (Not M3); 2001-2006 Spec E46 BMW 330i, 330ci; 2004-2006 E83 BMW X3 2.5i, X3 3.0i; and 2003-2006 Z4 BMW Z4 2.5i, Z4 3.0i.","brand":"Drift HQ","offers":[{"title":"Default Title","offer_id":52687852994872,"sku":"T53-SUBDFBUSHREARE46","price":45.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/662655835.webp?v=1784886761","url":"https:\/\/store.motormia.co\/products\/tech-53-rear-differential-bushing","provider":"MOTORMIA","version":"1.0","type":"link"}
