What does the +0.25mm sizing mean for these bearings?

The +0.25mm sizing indicates that these bearings are larger than standard size by 0.25 millimeters. This is typically used when the engine's main crankshaft journals have been machined down by 0.25mm to remove wear or damage, and these bearings will bring the clearance back to the proper specification.

What is the King XP overlay material?

The XP overlay is a high-performance bearing material developed by King Engine Bearings. It's a multi-layer construction designed to offer improved resistance to wiping and wear under demanding operating conditions, such as higher loads and temperatures.

Do these bearings come with installation instructions?

While these bearings are designed for a direct fit, it is always recommended to refer to the manufacturer's installation guidelines or a qualified mechanic for proper installation procedures. Ensuring correct torque specifications and crankshaft journal preparation is critical for bearing longevity.

About this part

Product Details

These King Engine Bearings main bearings are built with a high-performance XP overlay, a unique material designed to handle the increased loads and temperatures found in performance applications. This particular set is sized at +0.25mm, meaning it's intended for engines that have already been machined to this specification to correct wear or achieve a tighter clearance. They are specifically made for the Suzuki M16A engine, a common powerplant in many compact vehicles.

The XP overlay is a multi-layer material that includes a tough steel backing for structural integrity, a specialized aluminum-tin-lead alloy for excellent embeddability and conformability, and a thin, durable overlay. This overlay is engineered to resist wiping and maintain its integrity under extreme conditions, helping to protect your crankshaft from damage. King's design also incorporates features like optimized oil holes and chamfered edges to ensure proper oil flow and prevent binding during installation and operation.

When rebuilding or refreshing your M16A engine, especially if you're looking to improve its reliability or performance, using bearings that are precisely sized and made with advanced materials is crucial. This +0.25mm set is a solid option if your engine's main journals have been machined to this size. Always ensure your crankshaft journals are cleaned and measured accurately before installing new bearings.
