With a bearing-less rocker, customers could assemble the rockers without using assembly or any lubricant, which causes the rocker arm to seize immediately or damage the bushing or rocker arm. Using needle bearings will reduce the chance of damaging the rocker's arm. However, this is no excuse for not properly lubricating the valve train. When installing the rocker's arms, use assembly Lube.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cspan\u003e\u003c\/span\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003eThe rocker's arm is more vital than before, and the highest has a needle bearing on the market.

The roller tips reduce friction and wear on the valve tips. The shaft mounting also helps reduce distortion and deflection, improving valve movement truer to the camshaft profile, resulting in better performance.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cspan\u003e\u003c\/span\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003eThe Rockers have a 1.3:1 ratio, and rocker arm geometry plays a significant role in valve movement. Since the rocker arm should increase the valve lift, it will increase valve acceleration and duration, especially from .150\" and higher. Performance will increase, but your spring pressure may need to improve, too. Increasing weight, lift, and valve acceleration will require more spring pressure.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e\u003cbr\u003e\u003cb\u003eRev Rocker Features:\u003c\/b\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eRocker Arms are made from aircraft billet aluminum\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eHarden Roller Tip with an oversized pressed-in axle with clip for increased strength\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eLarger Diameter Roller Tip for extra clearance\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eTitanium Lash Adjuster Nuts\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eIncreased material on the Rocker Arm Tip adds rigidity and strength.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eNeedle Bearing for the main shaft for improved durability and performance\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eThe main shaft includes snapping rings to secure the rockers, which are protected by brass washers between the rockers and on the outside of them.\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cbr\u003e\u003cspan\u003e*Pictures of 1.2 ratio rockers for reference\u003c\/span\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"GoKarts USA®","offers":[{"title":"Default Title","offer_id":43060098302011,"sku":"NR-1505","price":199.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0589\/5159\/8139\/files\/1504-2_9be4780b-5f1e-460a-beba-e4cd8eb5c616.jpg?v=1764893685","url":"https:\/\/gtcracing.com\/products\/ec-1-3-billet-aluminum-ratio-rockers","provider":"GTC Racing","version":"1.0","type":"link"}
