From the factory, the oil supply to the rocker arm is shut off as the valve is opened. This lack of lubrication can cause excessive wear on your valvetrain and premature failures, especially in high performance applications.\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003eThe XDP Shafts feature revised oil grooves that align with the oil hole in the bushing so you maintain a consistent oil supply. These shafts are manufactured from hardened 4130 chromoly for extreme durability. Each shaft comes ready to install and has threaded pipe plugs at each end so the shafts can be cleaned, inspected, and hot tanked during an engine rebuild. \u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003ch5\u003e\u003cspan\u003eFeatures:\u003c\/span\u003e\u003c\/h5\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cul\u003e\n\u003cli\u003eCNC Machined\u003c\/li\u003e\n\u003cli\u003e.250\" Wall Thickness\u003c\/li\u003e\n\u003cli\u003e4130 Chromoly Steel Construction \u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"cmp-product-force-font\"\u003e\n\u003ca href=\"https:\/\/www.xtremediesel.com\/xtreme-diesel-performance-xdp-product-warranty-availability#warranty\"\u003e\u003cspan\u003e\u003cstrong\u003e\u003cu\u003eManufacturer Warranty*:\u003c\/u\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/a\u003e\u003cbr\u003e2 Year \/ Unlimited Mileage\u003c\/div\u003e","brand":"XDP MFG","offers":[{"title":"Default Title","offer_id":51325555605792,"sku":"XD385","price":484.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0916\/3043\/6640\/files\/xdp-xd385-hd-rocker-arm-shafts-2001-2024-duramax-9246496.jpg?v=1779541630","url":"https:\/\/www.southerndieselsupply.com\/products\/xdp-xd385-hd-rocker-arm-shafts-2001-2024-duramax","provider":"Southern Diesel Supply","version":"1.0","type":"link"}
