It will not fit a standard 68mm or 70mm bore cylinder without proper machining and block preparation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Does this piston come with rings and a wrist pin?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA:\u003c\/strong\u003e No, this is the piston only. It is intended for tuners who already have the necessary hardware or are building a custom setup. If you need the complete assembly, please see our piston kit options.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What are the benefits of the reduced skirt design?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA:\u003c\/strong\u003e The design minimizes skirt drag against the cylinder wall, which reduces internal friction. This allows the engine to rev more freely and reach higher RPMs, helping you shave valuable time off your laps.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Do I need to hone my cylinder before installing this piston?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA:\u003c\/strong\u003e Yes. When installing a new piston, it is critical to ensure your cylinder bore is properly sized and honed to the correct clearance specifications to prevent seizure and ensure optimal ring seal.\u003c\/p\u003e\n\n\u003ch3\u003eRelated Products From Vendor\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/tpp-72mmblock-reinforced-big-bore-block-block-only-tpp-72mmblock\"\u003eTillotson 196cc Clone Reinforced Big Bore Block - 72mm - Modified\/Open Class\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/tpp-72mmpkit-tillotson-72mm-piston-kit-tpp-72mmpkit\"\u003eComplete Tillotson 72mm Piston Kit with Rings and Pin\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/tpp-72mmrs-ring-set-72mm-tpp-72mmrs\"\u003eTillotson 196cc Clone 72mm Piston Ring Set - OEM Replacement - Modified Class\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/tpp-frhg72-tillotson-fire-ring-head-gasket-72mm-bore-tpp-frhg72\"\u003eTillotson Fire Ring Head Gasket for 72mm Bore Engines\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/tpp-72mmwp-wrist-pin-for-72mm-piston-tpp-72mmwp\"\u003eTillotson 72mm Piston Wrist Pin - 138220006 - 196cc\/212cc Clone\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SwiftKarting","offers":[{"title":"Default Title","offer_id":48158110056707,"sku":"TPP-72MMP","price":33.97,"currency_code":"USD","in_stock":true}],"url":"https:\/\/phishstonesproducts.myshopify.com\/products\/tillotson-72mm-piston-for-big-bore-blocks","provider":"PhishStones Products","version":"1.0","type":"link"}
