Our oversized head stud washers are designed specifically for high horsepower Barra engines. Unlike the standard 23mm OD head stud washers, our much larger 28mm OD washers fill the entire head bolt boss. This allows for a better clamping force and covers the entire fastening surface area - making your engine much, much stronger.
To suit: Ford Falcon BARRA 6-Cyl Engines (BA, BF, FG & FGX 6-Cyl models). Inc. XR6 and XR6 Turbo models.
Each washer is made from 4340 grade billet steel, heat treated and zinc coated.
Washer Size: 28mm OD, 12mm centre hole, 4mm thick.
Sold in lots of 14 washers.
