Conrod bearing FAQs
Conrod bearings vs main bearings?
Conrod (big-end) bearings sit between the crankshaft and the connecting rods; mains support the crank in the block. Most rebuilds replace both as a set.
What undersize do I need?
Match the undersize to how far the crank’s rod journals have been ground. Your machinist can advise, or send us the measurements.
Do you have performance conrods?
We can source performance connecting rods and race-series bearings for higher-output builds — ask our team.
