This is our Level 5 system for the 350Z and Infinity G35 coupe. Featuring a newly designed outer stub that bolts on to our special billet c.v. for the wheel end. The center bars are made from 300M and are upgraded to 36 spline internals on both ends (up from the factory 27 spline). This system does not come with an inner c.v. so you will have to change it over from the factory axle. We provide a new 36 spline race for the inner and includes boots, clamps and grease to make it an easy install. We also offer a service where you can send in you factory axles and have us change the parts over for an extra 100.00. These axles are rated to 900HP with a 1-year warranty. Pictured with inner c.v.
