{"product_id":"n55-s55-crankshaft-hub","title":"N55 S55 Crankshaft Hub","description":"The Maximum PSI crankshaft hub is an original factory-spec component for BMW N55 and S55 engines. Positioned at the front end of the crankshaft, this hub is responsible for squeezing the timing chain and oil pump chain sprocket into place, secured by an M18 crankshaft hub bolt.\n\nWhile this component is generally considered a lifetime part, replacement may be necessary if the hub becomes excessively worn or if the threads for the harmonic balancer bolts sustain damage. This genuine version ensures compatibility with the latest BMW design revisions. Please note that this original design is not recommended for high-horsepower or tuned vehicle applications, where aftermarket upgrades may be preferred. Professional installation is advised as this process involves precision timing and valvetrain components.","brand":"BMW","offers":[{"title":"Default Title","offer_id":52662956458296,"sku":"11237574827","price":88.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687503215.jpg?v=1784322013","url":"https:\/\/store.motormia.co\/products\/n55-s55-crankshaft-hub","provider":"MOTORMIA","version":"1.0","type":"link"}
