Product Details

The King Engine Bearings MB4272MC0.75 is a main bearing set engineered for Holden Alloytec V6 engines, including the 175 and 190 variants. This is a 0.75mm oversize bearing set, designed for use in engines that have had their crankshaft journals machined to restore a proper running clearance.

King Engine Bearings is a globally recognized manufacturer of precision engine bearings, known for advanced metallurgy and tight manufacturing tolerances that meet or exceed OEM specifications. Their bearings are a popular choice for both professional engine rebuilders and performance applications.

Key Features:

  • Designed specifically for Holden Alloytec V6 engines (175 and 190 series)
  • 0.75mm oversize (0.030") – intended for use with reground crankshafts
  • Manufactured by King Engine Bearings, a trusted OEM-level supplier
  • Precision-engineered for consistent oil film thickness and reliable load distribution
  • High-quality tri-metal or bi-metal construction for excellent wear resistance and durability
  • Part of King's mSTEEL™ or Standard line of main bearings, built for long service life

These bearings are ideal for engine rebuilds where standard-size bearings are no longer suitable due to crankshaft wear or machining. Always verify journal diameter measurements before selecting an oversize bearing to ensure correct oil clearance.

Good service, good delivery.

Great selection, inventory, and customer service.

I had no issues with my order or customer service. They responded to my email promptly.

Easy navigation

Yes very easy

Was very satisfied with this transaction except for one thing.. Their ad that I responded to clearly stated "Free Shipping" but the final invoice included an insurance charge (which I did not ask for) AND shipping charges.. Don't offer free shipping and then not honor it.. Otherwise was a simple process and received the product in a timely fashion..

Everything was fine

Quick shipping, great price. Very happy overall
