Be sure to compare your existing lifters to the images in the provided instructions — only one style of stock 33mm lifter is compatible.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cstrong\u003e35mm Setup:\u003c\/strong\u003e Alternatively, you can use M50 cam trays with 35 mm diameter Volkswagen-style lifters (similar to part number 050109309H). 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\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\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\u003eNote:\u003c\/strong\u003e When installing in an M50 engine, lifter trays from an M52, S52, or M54 must be used.\u003c\/p\u003e\u003cp\u003eEach kit includes two shim thicknesses.
