The Rein Automotive line of OE quality replacement parts has been around since 2007. Specializing in coolant hoses, undercar parts (suspension & drivetrain), axle boots and wheel bearings, Rein offers most of the common maintenance wear items for your car. With a name like Rein (“pure” in German) you know they must be manufacturing everything to the highest OE standards.

Left = Driver side and Right = Passenger side.

All parts are priced individually unless identified as a set or kit. “Per car” notes identify how many of a given part your car has and
“Left/Right or Front/Rear” notes means the part fits the left or right side of the car. These parts are still sold individually and you’ll
need to select the appropriate quantity if you plan to replace more than one of this item.
