Product Details

The King Engine Bearings MB5353HP0.25 is a complete main bearing set designed for the Ford 281 cubic inch (4.6L) SOHC 16-valve engine. This set is offered in a 0.25mm undersize to accommodate crankshafts that have been machined or show wear, making it an ideal solution for engine rebuilds and performance builds alike.

King's HP (High Performance) Series bearings are engineered for demanding applications, utilizing an advanced tri-metal construction with a copper-lead or aluminum alloy overlay that delivers superior load capacity, conformability, and fatigue resistance compared to standard OEM-style replacements. The HP series is a popular choice among engine builders working on both street performance and track-prepped Ford modular engines.

Key Features:

  • HP (High Performance) Series tri-metal bearing construction
  • 0.25mm undersize for use with reground or worn crankshafts
  • Enhanced fatigue resistance for high-RPM and high-load applications
  • Improved oil film retention for consistent lubrication under stress
  • Precision-machined to tight tolerances for proper oil clearance
  • Full main bearing set — includes all main bearings required for complete engine assembly
  • Compatible with Ford 281 CID / 4.6L SOHC 16V engines

King Engine Bearings is an ISO-certified manufacturer with decades of experience producing OEM and performance engine bearings. The MB5353HP0.25 is an excellent choice for builders seeking a reliable, high-performance upgrade over standard replacement bearings during a 4.6L Ford engine rebuild.

Easy to find on your website

Once i installed the BULLY DOG GT TRIPPLE DOG GAS TUNER PROGRAMER on my newerbody style 07 gmc sierra 1500, My mpg average went from 12 to 18. Instant improvement and performance. Not to mention the truck is lifted 7.5 in with 37 in tires. Easy programing settings takes minuets. The power the 5.3 puts out after my Bully Dog gas tuner was installed was fanominal. I will deff get my money back in fuel over about a year. Can't go wrong purchasing. This item. MUST HAVE PRODUCT.

helped me find the exact one i needed

so far so good..thank you!

So far so good. Quick, easy. Live the amazon option

easy enough so far

Good service

Autoplicity had the best price on the item I wanted. Order process was a little odd. I didn't get any confirmation of my order being placed. So 2 days later I sent an email asking if they had received it. They answered me very quickly, sent me an order confirmation with tracking number, and it turns out my item had already shipped so I had it the next day. So ordered 5/1 and had it in my hand 5/4.

Easy to use with the Amazon account. All ok!

no problems

Make sure your address matches paypal EXACTLY. I fought this thing for hours before I figured out what the problem was (was using a visa gift card).
