Dime Dave Posted July 2, 2016 Share Posted July 2, 2016 In the Fall of 2015 FutoFab, LLC acquired the parts stock and business assets of Wolf Creek Racing (WCR). In doing so we continued offering the WRX STi conversion stub axles and the WCR CV axle kits. The WCR purchase gave us the opportunity to make improvements on the Beta Motorsports STi stub axles that WCR sold, especially with some of the durability issues that had come to light. The FutoFab WRX STi conversion stub axles are made from heat treated forgings, not machined from a billet of alloy steel as the prior WCR/Beta Motorsport stubs were. Using the forging process to create the flange, the grain of the steel is deformed to flow into the flange. When the flanges are made by machining material away, the grain is cut. By using forgings it makes for a stronger and more durable axle stub. Our forgings are also heat treated to a Rockwell hardness of 50-55 prior to final machining. We have confirmed, thru lab testing that this hardness is maintained in our finished product for proper strength and durability. Our stub axles are made by a manufacturer with 25 years of driveline only experience. They specialize in production orders, one off applications and market their own line of custom axles for road, track, off road and rock crawling. The quickest way to identify a FutoFab WRX STi Stub axle is by its round flange.
