This is the new Pro-Level Rear Axle/Hub kit for the Evo VII/VIII/IX. This is the strongest axle kit we make for the Evo, rated to 1200whp with a 1 year warranty. This kit includes axles, hubs, wheel bearings and studs as found on our Level 5 kit, but the axles feature larger 36 spline bars (instead of 32 spline on the Level 5) and our new Ball & Cage inner CV. If you are going to be making over 1000whp, this is the kit for you.
