Overall Assessment

Review summaries highlight that customers highly regard the product's quality, practicality, and features. The product's bearings were admired for their great quality and were a preferred choice in race rebuilds and high RPM use. They also performed well in conjunction with rods and crankshafts bought from Speedway, indicating its excellent compatibility. Some reviwers mentioned their application in high-power mechanisms like twin turbo, NOS, and superchargers, suggesting the bearings' robustness and adaptability. However, a reviewer noted they could benefit from clearer instructions regarding identification for "upper" and "lower" bearings. Overall, the product outperforms in its intended use-cases, receiving recommendations for its reliable performance and endurance in substantial conditions.

Most of my pistons were installed but in checking the rod side clearance it was clear that something was wrong. The King XP rod bearings came in a box with two clear plastic trays, each containing 8 bearing halfs. No instructions were included so I just opened one tray and put a bearing into each rod and each cap. I was halfway through this when I noticed numbers 1 through 8 embossed into the bottom of each tray. Wait... were these supposed to indicate cylinder numbers? I'd never encountered that before. This morning I called King Bearings and asked about this. It turns out that one tray was intended as "upper" bearing halfs and the other was "lower". The fellow at King pointed out a small "U" and "L" that were etched on the back of each piece. He agreed that they needed to include paperwork that pointed this out to a customer. Apparently he's had many questions about this before. Now to remove the bearings that I installed and put the right ones in their place. Arrrggghhh.... Regards, Neil Tucson, AZ
