The ultimate in one-piece wheels. Forging is the process of forcing a solid billet of aluminum between the forging dies under an extreme amount of pressure. This creates a finished product that is very dense, very strong and therefore be very light, in fact the lightest of all wheels! The costs of tooling, development, equipment, etc., make this type of wheel very exclusive and usually demand a high price in the aftermarket. The term "Monoblock" is used throughout the industry to describe the 1-piece forged wheels. "Mono" meaning one, and "Block" meaning it was created from one block of aluminum. The block in this case is actually a round bar stock of high quality, aerospace-quality 6061-T6 Aluminum Alloy. The round bar is pressed in a huge forging machine, to stamp out a wheel shaped blank. Forging is a hot working process, and helps to align the grain structure of the alloy. This results in a very strong, very lightweight wheel construction material. The wheel blank is then flow-formed to create the outer barrel shape. Following that process, the wheel blank is loaded into a CNC milling machine and there the spoke pattern is milled out. Forged wheels are built to order and custom tailored to your needs. Therefore, PCD, size, width, offset, color combination can all be specifically manufactured as per your needs. It is the lightest and strongest of all, can be made in perfect fitment!
