New!

We are proudly introducing our 100% billet aluminum power steering reservoir for BMWs. There is no doubt, the plastic power steering reservoir commonly cracks and leaks over time. We decided to change this by CAD designing our own billet aluminum version out of one block of 6064 aircraft grade aluminum. We then created our own billet power steering reservoir cap as well to not only match the design, but prevent future leaks. Finally, we anodized the entire product in black to match the original. 

The reservoir was designed a little taller to allow more capacity of fluid to prevent heat expansion and overflow in track or drift applications.  The bottom of the reservoir contains a baffle to reduce foaming. 

This aluminum reservoir not only looks great in your engine bay, but will be the last one you will buy.  This reservoir is completely plug and play to the original. This will fit many different applications.
