What does 'STD' size mean for these rod bearings?

STD stands for standard size. This means the bearings are designed to fit a crankshaft journal that has not been machined or ground undersize. If your crankshaft has been reconditioned to a specific undersize (like -010 or -020), you would need a correspondingly sized bearing set.

What is the advantage of the bi-metal aluminum material?

The bi-metal aluminum construction offers a good balance of strength and conformability. This material is well-suited for high-performance applications, helping to absorb shock loads and maintain oil film under demanding conditions.

Are these bearings suitable for a stock LS engine rebuild?

Yes, these standard size bearings are suitable for a stock LS engine rebuild, provided the crankshaft journals are within factory specifications. The lead-free composite and bi-metal aluminum construction offer improved performance and durability over stock bearings.

About this part

Product Details

If you're working on a Chevrolet LS engine, like those found in many trucks and performance cars from the late 90s onward, these King Engine Bearings rod bearings are a solid choice. They're built with a bi-metal aluminum material that's designed for high performance, offering a lead-free composite for a more environmentally safe option. King has been specializing in bearings since 1960, focusing on making them as good as they can be.

These bearings are a standard size (STD), meaning they're meant to fit crankshafts that are still within their original specifications. The bi-metal aluminum construction is key here; it's a well-built material that handles the stresses of connecting rods, especially in performance applications where you might be pushing the engine a bit harder. This set is designed to fit a wide range of Chevrolet SBC Gen III/IV LS engines, covering displacements from 4.8L up to 6.0L, and is suitable for many vehicles including Cadillac CTS, Chevrolet Silverado, and GMC Sierra models.
