Q & A

What's in the Box

  • Bi-metal aluminum silicon alloy featuring fine micro-bore finish
  • Mains and rods are narrowed for large radius crankshafts
  • Greater rod bearing height improves bearing-to-bore contact/heat transfer and reduces spin potential at high RPM
  • 0.015" thick top layer for superior macro particle embedability and conformability
  • 40 Vickers hardness to resist overlay migration and extrusion
  • 450°F heat threshold for superior protection against friction and overheating

Application

  • High-load, short-duration racing such as drag racing, tractor pulls, monster trucks, etc.
  • Medium-load, long-duration racing such as circle track engines using nodular cast iron crankshafts

Clevite H-Series 1969-Up Small Block Chevy Rod Bearings
SKU-757R663H
                        Clevite's H-Series was developed primarily for use in NASCAR type racing, but  they are suitable for all types of competition engines. These sets are  specifically for 1969-Up 302-305-327-350 S/B Chevy "Large Journal" engine (with 2.100" rod  journals).
  • Use H-series bearings with crankshafts that have oversize fillets and where engines run in the medium to high RPM range.
  • H-Series bearings should be used if contact patterns obtained with P-series parts are too narrow. Contact pattern should ideally cover 2/3 to 3/4 of the bearing surface.
  • If you aren't sure which type of performance bearing to start with, the H-Series will be your best choice.
  • X001 has .001" extra bearing clearance

  • Use P-Series rod bearings where extremely high RPM’s cause severe rod bore close-in.
  • Large Journal
  • Use P-Series main bearings where higher eccentricity is desired to narrow bearing contact patterns and to provide increased oiling to rod bearings.

  • Will not plug filters after initial engine start-up, unlike other assembly lubes
  • Provides 3x greater film strength than conventional black Molybdenum Disulfide greases
  • Excellent rust and corrosion inhibitor, allows for long-term storage
  • For use on camshafts, lifters, pushrods, piston skirts, main and rod bearings, and bolt threads
  • Do not use on exhaust bolts or other high temperature bolts which require an anti-seize
  • Recommended and used by top camshaft and drivetrain manufacturers
