Clevite MS-1718P High Performance Main Bearing Set P-Series

The Clevite MS-1718P is a high-performance main bearing set from the P-Series line, engineered specifically for racing and competition engines operating at extreme RPMs. This bearing set features full 360-degree grooving to maximize oil flow to connecting rod bearings, making it ideal for applications where rod bearing oil starvation is a concern.

P-Series Design Features:

• High eccentricity design for narrow bearing contact patterns and increased rod oiling
• Full groove configuration maximizes oil delivery to connecting rods
• High crush design for maximum bearing retention
• Reduced overlay thickness prevents overlay fatigue and "hen tracking"
• TriMetal bearing construction for superior strength and durability
• Hardened steel backing for added strength and fretting resistance

Recommended Applications:

• Engines operating at extremely high RPM ranges
• Applications experiencing severe rod bore close-in conditions
• Situations where rod bearing oil starvation is evident (polishing, smearing, or discoloration)
• Racing and competition engines requiring maximum oil flow to rod bearings

The P-Series represents Clevite's original high-performance bearing line with proven reliability in demanding racing applications. These bearings use reduced overlay thickness compared to standard bearings to prevent fatigue under extreme loads, while the full groove design ensures connecting rods receive adequate lubrication even under the most demanding conditions.

Note: P-Series main bearings are designed with greater eccentricity than H-Series bearings. If contact patterns are too narrow or if your application doesn't require maximum rod oiling, consider H-Series bearings instead.
