This is similar to our Level 5 axle except the outer CV is made from Billet Chromoly and the internals are also made from the same high grade material, while using the original spline size to fit the stock hubs. To make sure the center bar was up to the task of hard launches, autocross and rally demands, we have decided to use the new 300M material we have been getting directly from the mill in Sweden (*Ovar). This material has proven to be without a doubt the strongest and most resilient bar material we have used to date. Also we have recently changed the inner CV from a tripod design to a full ball and cage design with a larger radius to the spline plug for added strength.

THE DRIVESHAFT SHOP 2009-2015 STi Direct Fit 800HP Rear Axles

Its been a long time coming for this set of axles. When the STi came out, many had surpassed the 600HP mark and we went right from the axle bar upgrades using the factory CV's to the level 5 Axle and Hub kits. Some time has passed and the cars are starting to get older, and most builds are under 800HP so we decided to make a direct bolt in axle that will support 800WHP.

NOTE: These axle are for the 2009-2015 STi models ONLY
