What is the STDX size for these bearings?

The STDX size indicates that these bearings are 0.001 inch undersize compared to standard bearings. This allows for more adjustability during engine assembly, especially if your crankshaft journals are slightly out of spec or if you're aiming for a specific oil clearance.

What is the pMax Black overlay?

The pMax Black overlay is a specific material used by King Engine Bearings on their performance bearings. It's designed to offer improved load-bearing capacity and better performance under higher temperatures compared to standard race bearing materials.

Do these bearings come with assembly lube?

This set includes the rod bearings themselves. It is recommended to use a high-quality engine assembly lubricant when installing these bearings to ensure proper lubrication during initial startup and break-in.

About this part

Product Details

If you're rebuilding the engine in your 2003-2005 Dodge Neon SRT-4, or another compatible vehicle from the EDZ SRT 4 Turbo family, these King Engine Bearings are a solid choice for performance applications. These are connecting rod bearings, which are critical for maintaining proper oil clearance between the crankshaft and connecting rods as the engine spins. Getting this clearance right is key to engine longevity and performance, especially when you're pushing the engine harder than stock.

These bearings feature a tri-metal construction with a pMax Black overlay, which is a step up from their standard race bearings. This advanced material helps them handle higher loads and temperatures, making them well-suited for modified engines. They come in the STDX size, which is 0.001 inch undersize, offering a bit more adjustability during engine assembly if your crankshaft journals are slightly out of spec or if you're aiming for a tighter oil clearance. King is a well-known name in performance engine components, and these bearings reflect that reputation.

When installing these bearings, remember to always check your crankshaft journal dimensions and ensure they are within the specified tolerance for the STDX size. It's also important to use the correct assembly lube and follow the manufacturer's torque specifications for your connecting rod bolts.
