NEW Mack MP8 & Volvo D13 Rod Bearing Pair | 20580558, 20508264 | Mack MP8 / Volvo D13

New pair of rod bearings for Mack MP8 & Volvo D13 engines. Six pairs are needed for a complete set.

Both rods and mains have high crush for maximum retention, and a reduced overlay thickness to prevent overlay fatigue, sometimes referred to as hen tracking.

Upgrade your rod bearings where extremely high RPM’s cause severe rod bore close-in. This is typically indicated by nearly full parting line to parting line shaft contact with bearings having less eccentricity. The rod bearings in this series typically have the greatest amount of eccentricity. Rod bearings also use a hardened steel back for added strength and resistance to fretting. This carries a one year warranty.

Features:

• Seizure Resistance – bearings have as much as 40% better seizure resistance than competitors’ engine bearings
• Load Capacity – bearings can withstand over 60% higher loads for extended periods compared to competitor bearings
• Embeddability & Conformability – bearing offers a superior surface for forgiveness, offering additional protection that can be extremely beneficial in an engine that is poorly maintained
• Durability – bearings not only exceed light vehicle OE durability requirements of 150,000 miles, they also exceed heavy vehicle OE durability requirements of 300,000 miles
