SPORT-PARTS INC. Crankshaft Bearing
Optimize engine performance with the SPORT-PARTS INC. Crankshaft Bearing—engineered for smooth rotation, reduced friction, and long-lasting reliability. Designed to withstand high loads and temperatures, this premium bearing supports precise crankshaft alignment for consistent power delivery and extended engine life.
Key Features
-
High-Performance Design: Built for durability in demanding powersports and small-engine applications.
-
C3 and C4 Clearances: Features “greater than standard” internal clearance to accommodate thermal expansion, high RPM, and heavy loads without compromising stability.
-
Smooth, Quiet Operation: Precision surfaces minimize vibration and reduce wear on mating components.
-
Heat and Corrosion Resistant: Premium materials and lubrication compatibility for harsh environments.
-
Easy Fitment: Manufactured to tight tolerances for reliable installation and OEM-level performance.
Why Choose C3 vs. C4?
-
C3: Ideal for general high-speed use where moderate thermal expansion occurs.
-
C4: Best for extreme RPM, higher operating temperatures, or tighter engine cases requiring additional internal clearance.
Benefits
- Improves engine efficiency and longevity
- Reduces friction and operating temperatures
- Maintains precise crankshaft alignment under load
Note: Verify bearing size, clearance class (C3 or C4), and compatibility with your specific engine model before purchase.
