LIMITED AVAILABILITY: This listing is for SIX (6) Pieces of what i believe are 440-X3 or 440-X4 DOWNFORCE RARE EARTH NEODYMIUM MAGNETS WITH PLASTIC RETAINERS. Never Installed TYCO Malaysia Factory Stock; No idea what Gauss Magnetic Flux Density they are. *Condition VINTAGE: chrome magnetic coating is flaking off, but still usable. The story is that TYCO Toys was sold to Mattel Co. right around 1999. At that time, TYCO had nearly developed a next generation chassis with a (blue) armature Rare Earth Magnets for SUPER GRIPPING POWER. The issue that arose in real life use was that, the friction torque of the chassis combined to literally melt the plastic alongside the rails ON SMALL 8' long Starter Sets! (They should pose no problem on longer tracks where the rails have a chance to dissipate some of the heat from the friction.) Quite a problem seeing they had already produced X-3 Literature some packaging for international cars sets. NONE of the Packaged 440-X3 HPX-3 Vehicle or sets have the rare earth magnets, although Racing Warriors are commonly found with the (better?) Blue Armature. These are factory direct i am describing them to the best of my knowledge. Admittedly not a racer, i did wedge the old 440-X2 magnet out put the new X-3 one in with some ease, albeit not too gently. Disassembling the chassis entirely, allows the Magnets Shoe to slide in very nicely where the 440-X2 stock magnet was as you can see, looks perfectly factory, as it is. They will fit a TYCO 440-X2 Style chassis specifically, But the magnets could be removed from the gray 'shoe' sunk into any chassis!
