The piston meters oil flow as the shaft strokes, so hole count and diameter set the damping character. Three 1.4mm holes flow more oil than a two-hole piston, producing a freer, more responsive damper that lets the suspension react quickly to bumps and generate mechanical grip. It is the usual choice for rough or low-traction tracks where a packed shock would skate across the surface.\u003c\/p\u003e\u003cp\u003ePistons and oil weight are tuned together, and swapping pistons often gives a cleaner result than moving to extreme oil weights, since hole count stays consistent as oil warms through a run. These install as a direct-fit tuning option in Kyosho's big bore shock sets, fitting the Ultima RT6, RB6, and SC along with the Lazer ZX-5 series and the FS2 SP and SC-R SP models. Package includes two pistons.\u003c\/p\u003e","brand":"PowerHobby","offers":[{"title":"Default Title","offer_id":44532748451928,"sku":"KYOW5303-10","price":4.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0567\/0554\/8376\/files\/kyow5303-10_306dfca0-a77e-4683-bbc5-0106dfe5844d.jpg?v=1786241845","url":"https:\/\/beavertonmilestonehobby.com\/products\/kyosho-w5303-10-big-bore-shock-piston-3-hole-2","provider":"Beaverton Milestone Hobby","version":"1.0","type":"link"}
