Level 3.9 Axle/Hub system 600HP for the Acura Integra platform (1 year warranty) This axle/hub system is made and designed for the real fast street car or drag car with up to 600HP. This was the older level 5 (2004 and older) system and we have brought it out of retirement due to the fact a 600hp street car is now a normal thing. This has been one of the best know systems for a Honda platform to date and is still a staple in most tuner shops around the world. The kit comes with both axles made from 300M with billet inner housings. The outer c.v. is 20% larger than a factory one and is made from a Proprietary material that is brutally strong. The kit comes with a custom hub that is an exact replica of the factory one it just has the larger spline inside.
