Mahle Rings Pro Series Performance Rings Low Tension 4.125 Bore Moly Ring Set

If you're rebuilding the engine in your performance vehicle, getting the right piston rings is crucial for sealing and power. These Mahle Pro Series rings are designed for a 4.125 inch bore, featuring a low-tension design that works well in high-performance applications. The moly coating on the top ring helps reduce friction and wear, which is important for keeping your engine running smoothly under demanding conditions.

Mahle is a well-known name in engine components, and this Pro Series set is built to handle the stresses of performance builds. The low-tension design helps them conform to the cylinder wall, improving the seal between the piston and the cylinder. This means better compression and more efficient power delivery. Remember, these rings are not CARB approved and cannot be shipped to California.
