{"product_id":"qr25-balance-shaft-removal-kit","title":"QR25 Balance Shaft Removal Kit","description":"The JWT Balance Shaft Removal kit (part # OQR25-NOBAL) is engineered for QR25 performance engines, specifically those intended for high RPM operation. The stock QR25DE engine utilizes a balancer shaft assembly that spins at double the engine speed to counteract vibrations. While this provides a marginal reduction in perceived vibration, it significantly increases stress on the main bearings due to the opposing inertial mass it generates.\n\nThis kit offers a solution by allowing the removal of the factory balance shaft assembly. The increased rotational speeds of the balance shafts (potentially exceeding 14,000 RPM) place considerable stress on the engine's main bearings. By eliminating this component, the kit reduces this added stress, making it a crucial modification for any QR25 engine built for high-performance applications. The kit is constructed from aluminum.\n\nWhile specific installation instructions are not detailed, the removal of internal engine components typically requires a moderate to advanced level of mechanical skill and appropriate tools. It is advisable to consult a service manual for the specific vehicle and engine application.","brand":"JWT","offers":[{"title":"Default Title","offer_id":52662789800248,"sku":"OQR25-NOBAL","price":89.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687498117.jpg?v=1784321031","url":"https:\/\/store.motormia.co\/products\/qr25-balance-shaft-removal-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
