Billet No. 3 main bearing cap replacement for the Hyundai Excel G4FK engine.
Developed to address the common issue of the factory No. 3 main cap cracking in race engines.
This billet replacement is intended for use in competition engine builds and rebuilds, and is designed to meet the 2027 Circuit Excel rule requirements.
This cap also suits OEM factory bolts.
Because the cap is individually machined, the engine block must be line bored with the new cap fitted to ensure correct main bearing alignment and clearance.
Professional engine machining and assembly is required.
