What does '0.25 Oversized' mean for these bearings?

This means the bearings are designed to fit a crankshaft that has been machined down by 0.25mm. This is a common practice during engine rebuilds to restore proper clearances when the original crankshaft journals have been worn or resurfaced.

What is the 'pmax black' material?

The pmax black material refers to the tri-metal construction of the bearing surface. This type of material is often used in performance and racing applications due to its improved wear resistance and load-carrying capabilities compared to standard bearings.

Do these bearings come with installation instructions?

While these bearings are designed as a direct fit for the specified vehicles, it is always recommended to refer to the manufacturer's installation guidelines or consult a qualified mechanic for proper installation procedures.

About this part

Product Details

These King Engine Bearings rod bearings feature a pmax black tri-metal construction, a design choice often found in racing applications for its enhanced durability. They are specifically sized at 0.25mm oversized, meaning they are intended for crankshafts that have been machined down to accommodate this size during an engine rebuild. This set is built for the Renault Alliance and Encore models from the mid-80s, specifically those equipped with the 1.7L F2N engine.

The pmax black material is a key aspect of these bearings, offering a more robust surface compared to standard bearings. This can translate to better wear resistance, especially in engines that see more demanding use. When you're rebuilding the bottom end of your Renault's engine, choosing the right bearings is crucial for long-term reliability and performance. These are a solid option if your crankshaft has been prepped for an oversized bearing set.
