What does the +.026mm sizing mean for these bearings?

The +.026mm designation indicates that these main bearings are slightly smaller than standard size. They are intended for use in an engine where the crankshaft journals have been machined down by 0.026 millimeters to provide a fresh, precise surface for the new bearings.

What is the advantage of the XP tri-metal design?

King's XP bearings utilize a tri-metal construction with a specialized overlay. This design is known for its excellent load-carrying capacity and durability, making it suitable for high-performance engines that experience significant stress.

Are these bearings suitable for a stock Lancia Delta Integrale engine rebuild?

These are King XP bearings, which are a well-built option for performance applications. While they can be used in a rebuild, their +.026mm sizing means they are specifically for engines where the crankshaft has been machined to that undersize. Always confirm your engine's specifications before ordering.

Product Details

The King XP main bearings feature a unique tri-metal design with a special overlay that's .0005 inches thick. This advanced material composition is crucial for handling the high loads and stresses found in performance engines like those in the Lancia Delta Integrale. These bearings are specifically sized at +.026mm, meaning they are intended for engines that have already been machined to this undersize specification for a fresh rebuild.

King's XP bearings are well-built for demanding applications, offering improved strength and durability over standard bearings. The tri-metal construction provides excellent embeddability and conformability, allowing the bearings to adapt to the crankshaft surface for optimal oil film support. This attention to material science and precise sizing makes them a solid option for anyone rebuilding a performance engine where reliability and longevity are key.

When rebuilding your Lancia Delta Integrale's engine, using the correct bearing size is critical for proper oil clearance and engine health. Ensure your crankshaft has been machined to the +.026mm undersize before installing this set. Proper installation according to manufacturer guidelines will ensure these bearings perform as intended.
