{"product_id":"balance-shaft-elimination-kit","title":"Balance Shaft Elimination bushings","description":"\u003cp\u003eThe SBR Performance Balance Shaft Elimination (BSE) kit removes the balance shafts from your GM Ecotec engine, cutting rotating mass and freeing up power that would otherwise be lost spinning those shafts. For any serious Ecotec performance build, this is one of the first steps — the engine revs faster, pulls harder at the top end, and responds more sharply without that extra rotating weight dragging it down.\u003c\/p\u003e\n\n\u003ch2\u003eWhat It Does\u003c\/h2\u003e\n\u003cp\u003eThe factory balance shafts in the 2.0L, 2.2L, and 2.4L Ecotec exist to smooth out engine vibration for daily driving comfort. In a performance application, they're dead weight on the crankshaft. Removing them reduces rotating assembly mass by approximately 5 lbs, allowing the engine to spool up faster, rev more freely, and hold higher RPM with less parasitic drag.\u003c\/p\u003e\n\n\u003ch2\u003eWhat's Included\u003c\/h2\u003e\n\u003cp\u003eTwo CNC-machined aluminum bushings that press into the block to seal the oil passages left behind after the balance shafts are removed. The kit does not include idler shafts — you will modify your existing idler shafts by cutting them at the point just past the flanged section before installing the bushings.\u003c\/p\u003e\n\n\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\n\u003cp\u003eThe aluminum bushings must be pressed into the block properly to seal the oil passages. This is a builder-level modification — if you're not comfortable with engine disassembly and press-fit work, have a machine shop handle the installation.
