Clevite GM Pass & Trk 287 288 303 316 324 326 336 347 350 370 389 400 Con Rod Bearing Set

If you're rebuilding a classic GM V8 engine, like those found in many Pontiac Catalinas or Oldsmobile 98s from the 50s through the 70s, these Clevite H-Series connecting rod bearings are a solid choice. They're built for engines that see a good amount of RPMs and are designed to work with crankshafts that have slightly larger fillet radii, which is common in performance applications. This set covers a wide range of popular GM displacement engines, from the 287ci all the way up to the 400ci.

What sets these H-Series bearings apart is their construction. They have a medium level of eccentricity, which helps with oil flow, and a high crush design that ensures they seat firmly in the connecting rod. Importantly, they are made without flash plating. This allows the bearing material to seat directly against the crankshaft, promoting better heat transfer and a more stable bearing surface, especially important when you're running the engine hard at higher RPMs. The hardened steel back and thin overlay add to their durability.
