Complete set covers all 8 connecting rod journals for the V8 application - one set required per engine.
Fitment:
Enginetech rod bearings are engineered to OEM specifications, drawing on over 40 years of engine rebuilding expertise to deliver the precise clearance, crush, and eccentricity required for long-term durability under both stock and moderate-performance loads. Each set is application-specific: materials, wall thickness, oil clearance, and surface finish are all matched to the connecting rod journal geometry and operating loads of the engine family it serves. Rod bearings are a wear component and must be selected to match the crankshaft journal size - bearings sized for standard journals will not seat correctly on undersize-machined journals and vice versa, so verify your journal measurement with a precision micrometer before ordering or installing. Always replace rod bearings as a complete set. Mixing new bearings with used bearings produces uneven oil clearance across cylinders and accelerates wear on the freshly installed bearings - the small cost of a complete set is insurance against premature failure on the bearings you just paid to install. Enginetech documents every set with clear application-specific notes, journal-size designation, and cross-references so the right part lands on the bench the first time.
