About this part

Product Details

This is a King Engine Bearings performance main bearing set for your Nissan SR20DE or SR20DET engine. Specifically, you get the main bearings, which are a crucial part of your engine's rotating assembly. These bearings sit between the crankshaft and the engine block, allowing the crankshaft to spin smoothly while supporting its weight and the forces from combustion. This set is sized at 0.50mm undersize, meaning it's intended for crankshafts that have been machined down by that amount to correct wear or runout.

The pmax black racing line construction is a notable feature here. This is King's performance material designed for demanding applications where oil clearance is tighter and loads are higher. It's built to handle the stresses of performance engines, offering improved durability and consistent performance under pressure. If you're rebuilding the bottom end of your SR20, especially for performance use, these bearings are a solid option to consider for their robust construction.
