Double-check your part number before ordering. POP-UP DOME PISTON DESIGN The pop-up dome design raises the compression ratio compared to a flat-top piston. When rebuilding an engine that came from the factory with a flat-top piston, installing a pop-up dome piston will produce measurably higher compression readings. This can improve engine responsiveness under load. CROSS-REFERENCES STIHL OEM PART NUMBER Current: 4283-030-2003 (also written 4283 030 2003 or 42830302003) INSTALLATION NOTES Use a piston ring compressor when installing the new piston and ring to avoid ring damage. When installing a pop-up dome piston, verify piston-to-head clearance before running the engine to ensure the dome does not contact the cylinder head at TDC. If your blower failed due to a lean seizure, air leak, or fuel system issue, address those underlying causes before installing the new kit to avoid re-failure. EQUIPMENT APPLICATIONS The Stihl BR800 backpack blower is Stihl's flagship commercial-grade blower, targeted at professional landscapers, municipal grounds crews, and commercial property maintenance. The Magnum, Magnum X, and C-E variants are made in America at Stihl's Virginia Beach facility.
