This is a pair of pre-sized auxiliary shaft bearings for all DOHC Fiat and Lancia engines.
Beware of bearings from vendors that are not presized, but rather "ream to fit", requiring special tools that are practically non-existent, even in most accomplished machine shops!
Press these in and you're ready to go! A must-have for a complete engine rebuild. Weak oil pressure in a tired engine can often be attributed to worn aux-shaft bearings.
New and unused.
