These OE style Driveshaft Carrier Bearings are available for 1963-72 Chevy-GMC trucks and 1958-64 Chevy Impala. These are factory style replacements with that OE appearance. If you are running a High Hoursepower / High Torque engine, we recommend going with our high tech billet aluminum carrier bearing. Built from T6061 aluminum with low deflection poly urethane insolator and precision bearing, these items can handle much more horse power and torque than the factory replacements
