ACL Race Series tri-metal main bearings are designed for demanding operating conditions and higher engine RPM. Their construction supports the bearing surface and improves bearing retention in the housing.
Increased eccentricity helps compensate for bore distortion at high RPM and assists in forming a hydrodynamic oil film. The set contains ACL Race Series main bearings.
- High-strength overlay plate with reduced thickness for improved fatigue properties
- Increased crush for improved bearing retention
- Flash plating eliminated from the back for improved heat transfer and grip in the housing
- Increased eccentricity to compensate for bore distortion at high RPM
- 3/4-grooved main bearings to optimize load-carrying surface area and oil flow to the conrod bearings
- Tight, consistent wall tolerances to help maintain consistent clearances
Suitable for: Kia Stinger I (CK).
Engines: Lambda 3.8, Lambda 3.3, Lambda 3.5, Lambda II 3.3 (G6DA, G6DB, G6DC, G6DH). Please check your vehicle’s engine code (registration document or VIN) before ordering; if in doubt, contact us and we will check for you.
Sizes
STD is the standard size for an unground crankshaft. Undersizes (−0.25 mm, −0.50 mm …) are for a reground crank, and “+0.025 mm clearance” (X) is for highly stressed engines. Your machine shop chooses the size after measuring.
