Mahle is well-known for making solid engine components, and this set of NHRA Pro Stock oil rings is no exception. If you're building a serious performance engine, especially one destined for drag racing, these rings are designed to handle the demands of high-horsepower applications. They feature a 4.710-inch bore size and a 2.0mm width, with a .129-inch groove width, making them suitable for specific high-performance piston designs.

This bulk set comes with 48 rings, which is ideal for shops or builders working on multiple engines or needing spares.
