Boundary OPG (oil pump gears) for the 5.0L Mustang GT are machined in matched sets, and shipped with blueprinting paperwork. Our gears have been proven in applications of up to 400HP per Liter.


Application: Ford 5.0L Mustang GT, 2011-2020


Our OPG and Crankshaft gears are cut from special heat treated chromoly billets, We guarantee your gears forever. We have found these gears to be nearly indestructible in all applications, and if you do ever manage to break a set we'll happily replace it for free, Unlike others selling oil pump gears on the side, this is our one and only specialty and we take pride in the fact no one has ever broke a set of our gears.


The sprockets are cut from American 4340 chromoly steel billets, hardened to Rockwell C scale hardness of 50-55. These come with an anti-burst ring that make the part 50% stronger then the stock design. Great materials and design have created the strongest crank sprocket on the market at a price that keeps you racing!



Same gears we use in our 1000+ HP Builds.

    Must have upgrade

    The OPG/ CSG was packaged very well, shipping and communication with BCR was very quick and was very satisfied with my experience. It took about 11-12 hours to install but it’s well worth it especially if you plan on boosting your car.
