Now available for the 2009-2012 Hyundai Genesis Coupe 2.0 and 3.8 is the 300M Axle Bar Upgrade. This is a set of bars made from 300M that will replace the factory axle bars and re-use your factory inner and outer CV's (Inner and Outer CV's are not included). The factory CV's are made from a high grade material very close to our 4130 chromoly, but the center bars are made from a brittle lower grade material. What we have made is a custom set of areospace grade 300M torsional center bars that will fit your stock inner and outer CV. This upgrade will work with the 2.0 and 3.8 models and the kit comes with both axle bars, boots, clamps and grease.
