2006-2011 Civic Si (FG/FA) 850HP Level 5.9 Axle/Hub Kit. The new level 5.9 axle/hub set, similar to our Level 5 system but with some major upgrades, the inner cv and now featuring our new tapered high quality aircraft grade axle bars. We now have created a Pro race worthy system that works with the standard spline size on the differential end, that can be used with Quaife, Wavetrac and other aftermarket limited slip diffs and spools. What we have done is made a new ball & cage inner cv from high quality chromoly. This inner cv now has 6 contact points and is stronger than a Porsche 930 (108mm) cv (same cv used by many high dollar systems). This along with the 33 spline outer and new 36 spline tapered bars makes it the strongest set of axles to date. The Kit comes with both axles and a set of custom hubs that will fit the stock bearing sizes and extended ARP studs. This system is designed for 850WHP and tire size will not affect its strength.
