Features & Product Details

Its been a long time coming for this set of axles. When the STi came out, many had surpassed the 600HP mark and they 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 they decided to make a direct bolt in axle that will support 800WHP.

This is similar to their 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, they have decided to use the new 300M material they 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 they have used to date. Also they 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. 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).

Fitment note:

  • Because this driveshaft is used across multiple models and years, there may be issues with wheel center cap fitment after axle installation.

    QUESTIONS & ANSWERS

    • Q: duration of service  waynewhitfield82.ww134571 day ago

      Hey, what is the service life on these axles? Thanks in advance!
      • 0 of 0 people found the following answer helpful

        A:  We cannot specify a guaranteed life as it would all depend on other mods and how much power you are pushing.

    • Q: DCCD control  What’s best?10 days ago

      will the installation of this upgrade make me lost the DCCD control?
    • Q: Hubs?  Abiel10 months ago

      Recently did an 07’ 6 speed STi swap. Kept my R160 in order to keep my 5x100 hubs. Will this axle set allow me to maintain my 5x100s or would I need to go R180 and do hybrids?
      • 0 of 0 people found the following answer helpful

        A:  You would need to run the R180 and 5x114.3 hubs to run these axles.

        A:  Hi Abiel, We can offer an axle for your setup but it would be best to call the office to get the correct components ordered.
