Driveshaft Shop 800HP Direct Bolt-In Rear Axles - 09-18 STi
2009-2018 Subaru STi
Sold as the pair of rear axles or individually as needed.
When the STi came out, many had surpassed the 600HP mark and the Driveshaft Shop 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 these cars are starting to get older, and most builds are under 800HP so DSS decided to make a direct bolt in axle that will support 800WHP.
This is similar to the DSS 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, DSS decided to use the new 300M material directly from their 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.
The inner CV was also changed from a tripod design to a full ball and cage design with a larger radius to the spline plug for added strength. So there you have it, a direct fit axle that will with stand the most violent launches, time attack or rally applications (ask about the road rally package that uses a ultra high grade grease and vented boots).
