These pistons share many advanced features with the Wiseco HD1400 series for extremely high-power configurations.\u003c\/p\u003e\n\n\u003cp\u003eThey include upgraded pins with a 5.34 mm wall thickness and Armor Plating coating to reduce the negative effects of intense heat in turbocharged and nitrous\/methanol setups. Each ZRP piston for this application incorporates an ArmorGlide anti-friction coating on the skirt to minimize wear during break-in and reduce friction on the cylinder wall. Our pistons are manufactured using proprietary forgings, which provides a lightweight piston with superior strength and an optimal design. Additionally, the valve pockets are larger and deeper than those in original pistons to accommodate high-lift camshafts. Furthermore, the pistons feature offset pins and anti-detonation and gas pressure grooves to prolong the life of the rings.\u003c\/p\u003e\n\n\u003cp\u003eWhat is Armor Plating coating?\u003c\/p\u003e\n\n\u003cp\u003eThe Armor Plating coating gives them a bronze tone on the top and in the piston pin hole. This abrasion-resistant coating increases the hardness of the aluminum, improves the durability of the ring grooves, prevents piston ring micro-welding, reduces carbon buildup, and fights detonation corrosion. Additionally, the Armor Plating coating reduces the temperature of the piston head by an average of 20°C.\u003c\/p\u003e\n\n\u003cp\u003eWhat is the ArmorGlide anti-friction piston skirt coating?\u003c\/p\u003e\n\n\u003cp\u003eThe ArmorGlide piston skirt coating is made with a molybdenum solid-film lubricant and is permanently bonded to the pistons. One of its main features is resistance to scuffing and friction reduction, which ensures quiet operation. Naturally, piston rocking and noise are reduced, and power is increased.\u003cbr\u003e\nAdditional information\u003c\/p\u003e\n\n\u003cp\u003eApplication\u003c\/p\u003e\n\n\u003cp\u003e2.0L 4G63 EVO 1-9\u003c\/p\u003e\n\n\u003cp\u003eBore\u003c\/p\u003e\n\n\u003cp\u003e85.25 mm\u003c\/p\u003e\n\n\u003cp\u003eCompression Height\u003c\/p\u003e\n\n\u003cp\u003e25.80\u003c\/p\u003e\n\n\u003cp\u003eCompression Ratio\u003c\/p\u003e\n\n\u003cp\u003e9.0:1 \/ 8.52:1\u003c\/p\u003e\n\n\u003cp\u003eDeck Clearance\u003c\/p\u003e\n\n\u003cp\u003e-0.20\u003c\/p\u003e\n\n\u003cp\u003eDome CC\u003c\/p\u003e\n\n\u003cp\u003e-16.36\u003c\/p\u003e\n\n\u003cp\u003eEngine Number\u003c\/p\u003e\n\n\u003cp\u003e4G63 \/ Evo 4-9 \/ 4G64\u003c\/p\u003e\n\n\u003cp\u003eRod Length\u003c\/p\u003e\n\n\u003cp\u003e156.00\u003c\/p\u003e\n\n\u003cp\u003eNotes\u003c\/p\u003e\n\n\u003cp\u003e94.0 mm long stroke crankshaft with 156 mm connecting rods\u003c\/p\u003e\n\n\u003cp\u003eOEM Compression Ratio\u003c\/p\u003e\n\n\u003cp\u003e8.8:1\u003c\/p\u003e\n\n\u003cp\u003ePin Diameter\u003c\/p\u003e\n\n\u003cp\u003e22.00 mm\u003c\/p\u003e\n\n\u003cp\u003ePiston Material\u003c\/p\u003e\n\n\u003cp\u003e2618 Low Silicon, High Expansion Alloy\u003c\/p\u003e\n\n\u003cp\u003eRing Set\u003c\/p\u003e\n\n\u003cp\u003e21-GNH8550\u003c\/p\u003e\n\n\u003cp\u003eSet of\u003c\/p\u003e\n\n\u003cp\u003e4\u003c\/p\u003e\n\n\u003cp\u003eStroke\u003c\/p\u003e\n\n\u003cp\u003e94.00 mm\u003c\/p\u003e\n\n\u003cp\u003eThickness\u003c\/p\u003e\n\n\u003cp\u003e1.00 mm\u003c\/p\u003e\n\n\u003cp\u003eWeight\u003c\/p\u003e\n\n\u003cp\u003e323 g\u003c\/p\u003e\n\n\u003cp\u003eWrist Pin Pn\u003c\/p\u003e\n\n\u003cp\u003eS722\u003c\/p\u003e","brand":"ZRP","offers":[{"title":"Default Title","offer_id":56965587337556,"sku":"ZRP-22403-852","price":1080.53,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1027\/4701\/3460\/files\/ZRP-22403-852_9f647a4d-3463-43dc-8e4a-389ece6bdcb0.jpg?v=1788484885","url":"https:\/\/www.thetunerlab.com\/en\/products\/pistones-forjados-zrp-de-wiseco-para-mitsubishi-4g63-evo-4-9-diametro-8525-mm-90-1-852-1-94-mm-x-156-mm","provider":"Thetunerlab","version":"1.0","type":"link"}
