In these cases the oil return hole must be re-located (lowered) to avoid excessive oil consumption.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003ctable\u003e\u003ctr\u003e\n\u003cth\u003eUnit\u003c\/th\u003e\n\u003ctd\u003eSET\u003c\/td\u003e\n\u003c\/tr\u003e\u003c\/table\u003e\u003ch2\u003eFitment\u003c\/h2\u003e\u003cp\u003e79-84 1340cc Shovel (NU)\u003c\/p\u003e\u003ch2\u003ePart numbers\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eSupplier SKU\u003c\/th\u003e\n\u003ctd\u003e944647\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eManufacturer part\u003c\/th\u003e\n\u003ctd\u003eKB288STD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"KB Performance Piston","offers":[{"title":"Default Title","offer_id":58636767232344,"sku":"944647","price":259.89,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0975\/8235\/0680\/files\/944647k.jpg?v=1791039153","url":"https:\/\/deathproofcycles.com\/products\/kb-performance-1340cc-shovel-piston-kit-std","provider":"Deathproof Cycles","version":"1.0","type":"link"}
