This is the correct right and left hand R.H.P. main bearing for triumph twins with the correct c3 clearance pn# 70-1591! For the record C2 is actually tighter than standard (or CN) bearing and will lead to catastrophic engine failure. Cn means clearance normal, again, the incorrect bearing for many triumph applications. Always check the clearance specs for your make and model to prevent damage!

PN# 70-1591 was used as both right and left main bearings, but not necessarily both at the same time depending which year / model engine you have. Please check your parts book to verify fitment prior to purchase.

Attention… This purchase is for a C3 clearance! Should you require CN clearance, see our recommended links.

Please note: Due the nature of the product, we unfortunately do not accept returns on bearings, service tools or electrical components. Please be confident about your purchase before ordering. If you have questions, please contact us.
