DriveShaft KF56 850HP Level 5.9 Axle/Hub Kit Honda Civic / CRX EF K-Series
Civic / CRX K-Series 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.
Recently OBX tried to duplicate our Level 5.9 axle. We tested the OBX axle against the original style 5.9 axle and the new version with tapered bars that we currently offer. Here are the results of the destructive testing:
OBX axles- withstood 3300 ft-lbs and 55 degrees twist (this is what a Level 2.9 axle breaks at, a Level 3.9 is about 3700 ft-lbs)
The original Level 5.9 axle (previous version) withstood 4850 ft-lbs and 80 degrees twist.
The new Level 5.9 axle with tapered bars(currently available) - 5400 ft-lbs and 250 degrees twist!!!!
The Level 5.9 axles, often imitated but NEVER DUPLICATED.
This system does not come with ABS Rings. The rings can be installed for an extra 100.00 (not discountable)
Please Note: The Level 5.9 hubs are made for 90-93 Integra knuckles. If you are using these for a 88-91 Civic / CRX, you must change the knuckles to the 90-93 Integra due to the wheel bearing size.
