DSS Subaru 2004 WRX STi 600HP Rear Axle Bar Upgrade


Subaru 2004 WRX STi Rear Axle Bar Upgrade. The STi is a very stout car from the factory, the inner and outer CV's are made from a Japanese spec material very close to our 4130 chromoly, but the center bars are made from a brittle lower grade material. What we have made is a custom set of aerospace grade center bars that will fit your stock inner and outer CV. This kit comes with both axle bars, boots, clamps and grease.

Please Note: This axle bar upgrade is for the 2004 STi ONLY. If you have a 2005-2007 STi, see part# SBR2
