{"product_id":"100-11-546-0001","title":"GSR M52TU \/ M54 Four-Bolt Oil Pump Shaft","description":"\u003cp\u003e \r\n  The GSR M52TU\/M54 Four Bolt Oil Pump Shaft is the ultimate piece of engine insurance for your non-M E46, Z3\/Z4 or any other M52TU\/M54-powered BMW. Whether your car is a race car, dual-duty street\/track car, or you simply enjoy spirited high-performance driving, your stock oil pump shaft is at risk for failure.  \r\n  \u003cbr\u003e \r\n  \u003cbr\u003e \r\n  The factory oil pump nut can back off, and the shaft has a known history of breaking at high RPM. Either of of these failures would quickly lead to oil starvation, leaving your engine as nothing but a very large and expensive multi-piece paperweight.  \r\n  \u003cbr\u003e \r\n  \u003cbr\u003e \r\n  GSR's M52TU\/M54 Four Bolt Oil Pump Shaft replaces the failure-prone single-nut OEM sprocket retaining system on the M52TU\/M54 engine. The replacement shaft is precision ground, machined, and hardened for superior wear characteristics and resistance to shear failure. The four-bolt mounting system prevents the pump nut from becoming loose and backing off. This package is far superior to welded or safety-wired versions of stock parts, or a single-fastener replacement. \r\n  \u003cbr\u003e \r\n  \u003cbr\u003e \r\n  Kit includes new pump shaft, sprocket, and inner rotor. Fully assembled - no pressing required.  \r\n  \u003cbr\u003e \r\n  \u003cbr\u003e \r\n  Note: M52TU engines are updated, dual VANOS equipped M52 units built in 1998-2000 and were only available in the E46 chassis. These pump upgrades are compatible with OE part number 11 41 7 501 568. This upgrade is NOT compatible with the M52 engines from an E36 chassis. \r\n  \u003cbr\u003e \r\n  \u003cbr\u003e \r\n  \u003cspan style=\"color:#ff0000;\"\u003e\u003cstrong\u003e$300 core charge is included in price and will be refunded upon receipt of your rebuild-able core.\u003c\/strong\u003e Core MUST be received within two weeks of delivery of replacement unit.
