The new “420 Series” wheels fit most of the “40” series super low profile monster truck tires. This popular race-bred dish design is available in both white (LOSB7010) and yellow (LOSB7011). The hi-impact nylon material offers both excellent impact resistance as well as good rigidity necessary for the abuse of monster truck racing and bashing. The LOSB3510 Wheel Hexes and Nuts are precision machined from premium grade aircraft aluminum alloy and then hard coated for smooth operation and wear resistance to both the mounting surface as well as the threads. Correct right and left hand thread 6mm nuts are included to mount the new 20mm hexes on the LST. With bigger, heavier, and more powerful monster trucks being built by serious thrashers and the low profile 40 series tires being used by racers, the need for a larger wheel hex has become much greater. These larger hexes not only provide unbeatable performance but enhance the overall durability and longevity over the smaller hexes as well. Installation is as simple as removing the standard nut, wheel, and hex, and replacing them with the 20mm hex, 6mm nut, wheel, and new aluminum 20mm wheel nut. Both the 420 Series wheels and the 20mm Wheel Hexes are sold in pairs as well as the LOSB3511 Replacement Nut Set that includes both the 6mm and 20mm nuts as used for the wheel hexes.
