The past decade has set an industry standard for running level 2.9 and 3.9 high-performance axles in FWD and AWD converted street cars. It is not uncommon for these street cars to produce upwards of 600+HP. In order to keep up with these demands, we have worked diligently this past year to perfect our new X4 direct fit axle sets for Honda/Acura platforms. These axles have been tested to withstand 700+HP in both forced induction and all motor applications. This design allows for the newly developed axles to fit OEM Honda/Acura 26-spline or 28-spline wheel hubs offered by many aftermarket manufacturers. We have tested these components on many different platforms across our product line and decided it was time to transition this design over to the ever-evolving high HP FWD street cars of today. The X4 axle features our proprietary in-house designed 2pc Chromoly outer CV housing with a 300M splined wheel stub, Axle bars, and differential spline plug. Our new axles were crafted with durability in mind, this is why we have incorporated our ball and cage style inner CVs as opposed to the OEM tripod style. There is no doubt that these revamped plug-and-play axles are ideal for fun on the streets and weekends at the tracks.
