Piston weight 350gr.  Piston pin weight 89gr.  Piston pin dia. .927\" \/ offset.  Head type: Dome with -6.7cc.  Compression height 1.263\".  Bore 3.875\".  Stroke 4.000\".  Rod length 7.667\".  Cyl. length 4.938\".  All KB forged pistons are made from 4032 alloy; a 11% silicon alloy that is formed in a forging press. Forging aluminum gives a superior strength and structural integrity on a molecular level; after which it is fully machined. The combination of this alloy and the forging process allows the piston to flex under detonation; or pre-ignition; giving the best resistance to cracking. Although 4032 has a low expansion rate; it is higher than the cast Hypereutectic. Therefore forged KB pistons will require about .001\" wider piston to wall clearance. Pistons are sold as sets; complete with wrist pin retaining rings; wrist pins and piston rings.   Note: All KB forged pistons come equipped with offset wrist pins \/ piston pins. There is a front and rear section on the piston and it is necessary to install it in the correct way. Please refer to the installation instructions; as provided with each piston set; prior to installation.\u003c\/p\u003e","brand":"Kb Performance Piston","offers":[{"title":"Default Title","offer_id":50010489061704,"sku":"944813","price":401.9,"currency_code":"EUR","in_stock":true}],"url":"https:\/\/holydeath.com\/products\/kb-performance-88-to-95-twin-cam-piston-kit-040","provider":"Holy Death Motorcycle Co.","version":"1.0","type":"link"}
