This stainless boxed oil pump pick up was engineered by Olds Performance Products. We incorporate a stainless box to prevent any chance of breakage that is seen commonly on mild steel boxed pick ups. Each pick up assembly gets tig welded in all areas and has a support strap added for additional strength. This stainless boxed pick up is recommended for the 9.0 to 9.125 inch deep sump pans. You simply get what you pay for, so why take the risk on a ruined engine from a pick up breaking. We offer a life time warranty on any of our pick ups and oil pans. Made in the USA.
