Clevite Part #: MS-909 VX (repalced by MS-909HXC )

Application: Chevrolet 305/307/327/350 (Main Bearings) Large Journal

These are top of the line Clevite 77 VX trimetal bearings designed for small block Chevy engines. These bearings are brand new surplus from a top NASCAR race team. NASCAR race teams generally purchase engine bearings by the case, so these bearings are not in the typical retail packaging. They are the same high quality Clevite 77 bearings, just with a much better price. The suggested retail price for a set of these bearings is $150 a set. Buy them here for less than wholesale cost!

These “VX” bearings provide .001” additional oil clearance for high performance and racing applications. This is a great way to free up horsepower in your engine and provide the extra clearance needed between the bearing and journal to prevent the bearing from contacting the crankshaft, which can happen at higher RPM when the main journals are most likely to distort.

“V Series”
The V series are the newest of the high performance bearings in the Clevite 77 line. These parts essentially duplicate the former Vandervell parts under the Clevite 77 part numbering system (same core part no. as standard passenger car parts but with a suffix letter “V”). All V series main sets use a single piece thrust bearing rather than the former Vandervell assembled type of construction. V series parts are not available with dowel holes or oversize chamfers. Extra clearance parts are available with a suffix VX (.001” extra clearance), and VXX (.002” extra clearance) for some applications. V series bearings do not have flash plating on the steel back.

The chief difference between the V series and all other Clevite 77 trimetal bearings is the use of a lead - indium overlay. Lead -indium overlay offers somewhat better conformability than lead-tin- copper overlay with slightly reduced wear resistance.

Note: These bearings do not have pre-drilled oiling holes. This allows the engine builder to precisely locate, size, and shape the oil hole for optimum engine oiling.
