Fitment Notes

Fits Chrysler Pentastar 3.6L ERB V6 engine code only - does not fit the 3.6L ERC or other Pentastar variants; verify engine code before ordering
Standard (STD) size - for use on crankshafts at factory main journal diameter; always measure journals before ordering
SI Series = bi-metal aluminum silicon construction with 2.5-3% silicon; ideal OE-replacement grade for street and daily-driver engine rebuilds
Available in +0.25mm and +0.50mm undersizes under separate part numbers for ground crankshafts
Does not fit the 3.6L SRT / 392 Hellcat / Scat Pack 6.4L / 5.7L HEMI variants - verify displacement and engine code before ordering

Features

Product Description

The King MB4518SI is a standard-size crankshaft main bearing set engineered for the Chrysler Pentastar 3.6L ERB V6 - one of the most widely deployed V6 engines in the FCA/Stellantis lineup, found across Chrysler, Dodge, Jeep, and Ram vehicles from 2011 through 2022. The SI Series uses a bi-metal aluminum silicon structure with 2.5-3% silicon content, providing excellent wear resistance and journal compatibility for OE-replacement grade engine rebuilds across a broad platform range including the Charger, Challenger, Grand Cherokee, Wrangler, Ram 1500, and ProMaster.

As a standard-size set, the MB4518SI is designed for Pentastar ERB crankshafts at factory main journal diameter and installs without modification. It is the correct choice for rebuilds where the crankshaft is within factory specification. Always confirm the engine code (ERB vs. ERC) and measure crankshaft journal diameters with a precision micrometer before ordering. Undersized variants are available under separate part numbers for crankshafts that have been reconditioned.
