These symptoms can have several possible causes, so oil-pressure testing, compression or leak-down testing, trouble-code diagnosis, and internal inspection should be completed before ordering parts.\u003c\/p\u003e\n\u003cp\u003eThis aftermarket engine rebuild kit is designed for select 2009–2018 Chrysler, Dodge, and Jeep vehicles equipped with a 5.7L V8 HEMI engine, MDS cylinder deactivation, and VVT. It combines camshaft and lifter service components with head-gasket parts, pistons and rings, intake and exhaust valves, and connecting rods for repairs involving both the valvetrain and the rotating assembly.\u003c\/p\u003e\n\u003cp\u003eThe camshaft and hydraulic roller lifters control valve movement and support MDS operation. The intake and exhaust valves regulate airflow and seal the combustion chambers, while the pistons and rings maintain compression and control oil. The connecting rods transfer combustion force from the pistons to the crankshaft. Because these components require extensive engine disassembly, this kit is intended for a professionally inspected engine rebuild rather than routine maintenance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDesigned for select 2009–2018 5.7L V8 HEMI applications equipped with both MDS and VVT.\u003c\/li\u003e\n\u003cli\u003eRetains the existing MDS cylinder-deactivation configuration; this is not an MDS-delete conversion kit.\u003c\/li\u003e\n\u003cli\u003eIncludes one camshaft, 16 hydraulic roller lifters, and four MDS-compatible lifter guide assemblies for coordinated valvetrain service.\u003c\/li\u003e\n\u003cli\u003eIncludes eight replacement pistons with a complete piston-ring set for compression and oil-control repairs; the selected piston size must match the measured cylinder bores.\u003c\/li\u003e\n\u003cli\u003eIncludes eight intake valves and eight exhaust valves for cylinder-head repairs involving confirmed valve or sealing damage.\u003c\/li\u003e\n\u003cli\u003eIncludes eight connecting rods for rotating-assembly service; crankshaft and bearing clearances must be measured during installation.\u003c\/li\u003e\n\u003cli\u003eIncludes cylinder-head gaskets, upper-engine gaskets, seals, and head bolts for disassembly and reassembly during the same repair.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eInstallation Notice\u003c\/h3\u003e\n\u003cp\u003eThis is a major internal-engine repair kit.

Confirm piston bank and directional placement, connecting-rod orientation, MDS lifter position, valve-to-piston clearance, and camshaft timing.\u003c\/p\u003e\n\u003cp\u003eIf camshaft or lifter damage produced metal debris, thoroughly clean the crankcase, oil passages, oil pickup, and related lubrication components before reassembly. Follow the applicable torque-angle, timing, lubrication, and oil-system priming procedures before startup.\u003c\/p\u003e","brand":"Susucar Auto Parts","offers":[{"title":"Default Title","offer_id":60542330568785,"sku":"CAMSKIT-014+PISTON-009+CROD-002+VALVE-001","price":799.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0639\/9354\/4785\/files\/susucar-_5.7L_HEMI_MDS_Engine_Rebuild_Kit_-main-01.webp?v=1789184102","url":"https:\/\/susucar.com\/es\/products\/5-7l-hemi-mds-engine-rebuild-kit-with-pistons-valves-rods-2009-2018","provider":"Susucar Auto Parts","version":"1.0","type":"link"}
