Sorry these gears do not have a horsepower rating. They are an OEM replacement gear set and they work well for use in street cars and circle track racing. If you are dealing with a high powered drag car that will be launching with a trans brake these gears are not made for that use.

Choosing a rear axle ratio depends on many factors including the type/size of vehicle, what the vehicle is being used for, the overall tire height, camshaft specs, etc. (the list goes on). So, we recommend that you call us at 800.979.0122 and speak with one of our knowledgeable Techs about your project. They will be able to recommend the proper gear ratio for your specific application.
