Part #: RA8528X4 - V2. After a long wait, this set of axles is finally here. When the STi first came out, many cars exceeded the 600HP mark. We've evolved from upgrading axle bars with factory CVs to Level 5 Axle and Hub kits. Now, as the cars age and most builds are under 800HP, we've created a direct - bolt - in axle that can handle 800WHP. Similar to our Level 5 axle, the outer CV is crafted from Billet Chromoly, and the internals are made of the same high - grade material. It uses the original spline size to fit stock hubs. To meet the demands of hard launches, autocross, and rallies, we use 300M material directly from a Swedish mill (*Ovar). This is the strongest and most resilient bar material we've used. We've also upgraded the inner CV from a tripod design to a full ball and cage design with a larger spline - plug radius for extra strength. This direct - fit axle can handle the most intense launches, time attacks, or rally applications. Ask about our road rally package with ultra - high - grade grease and vented boots. Note: These axles are for 2004 - 2007 STi models only. Price is for a single axle.
How to use: These axles are direct bolt - in, so they can be easily installed on your 2004 - 2007 Subaru STi. Just follow the standard installation procedures for rear axles. Remember to use proper tools and take safety precautions. Attention: These axles are only for 2004 - 2007 STi models. Do not try to use them on other models as it may lead to compatibility issues and safety risks. Maintenance: If you choose the road rally package, the ultra - high - grade grease will provide long - term lubrication. Check the axles regularly for any signs of wear or damage, especially after intense driving like time attacks or rallies. Keep the vented boots clean and make sure they are in good condition. If you notice any problems, have the axles inspected by a professional mechanic.
