These lifters match the M50 VANOS lifter dimensions but weigh only 48 grams — the same as M52 lifters — making them ideal for race and severe-duty applications due to their larger internal piston.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-start=\"1312\" data-end=\"1571\" class=\"\"\u003eUnlike traditional lash caps, these hardened steel shims install between the original lifter piston and cup, making it impossible for them to fall out of position. \u003cstrong data-start=\"1476\" data-end=\"1485\"\u003eNote:\u003c\/strong\u003e When installing in an M50 engine, lifter trays from an M52, S52, or M54 must be used.\u003c\/p\u003e\n\u003cp data-start=\"1573\" data-end=\"1744\" class=\"\"\u003eEach kit includes two shim thicknesses.
