Product Details

The King Engine Bearings MB5243XP0.25 is a precision-engineered main bearing set designed specifically for Nissan SR20DE engines requiring 0.25mm oversize bearings. Built for high-performance and racing applications, these bearings feature King's advanced pMax Black tri-metal construction for superior durability under extreme conditions.

Key Features:

  • pMax Black tri-metal construction with polymer coating for enhanced wear resistance
  • 0.25mm oversize for rebuilding worn crankshaft journals
  • Race-grade bearing design for high-performance and motorsport applications
  • Engineered specifically for Nissan SR20DE engines
  • Superior fatigue strength and load capacity compared to standard bearings
  • Reduced friction for improved horsepower and efficiency
  • Complete main bearing set for full engine rebuild

King's pMax Black bearings utilize a unique tri-metal structure with a specialized polymer overlay that provides exceptional protection during high-stress operation, making them ideal for turbocharged, supercharged, or naturally aspirated performance builds. The 0.25mm oversize allows machinists to restore proper clearances on engines with journal wear.

Thank you Autoplicity, My universeral hold down kit worked.

good price & prompt delivery... I was very pleased!

Overall good product and fast delivery.

The website is easy to use, images are clear, gave me confidence the part will be correct.

I may need to return the unopened part and i don't see the policy and procedure. Ill have to search on the site page. All legit solid businesses I've worked with in the past made this very clear and up front. Not to say you didn't I just haven't looked yet and its not in your face obvious.

Very easy to order

Everything I was looking for was in stock and shipped quickly!
