Product Details

The King Engine Bearings MB5511HP STDX is a high-performance main bearing set engineered for General Motors 326, 350, 389, and 400 cubic inch engines. Part of King's HP (High Performance) Racing Line, these bearings are designed to withstand the elevated loads, increased RPM, and reduced oil clearances demanded by performance and competition applications.

Key Features:

  • HP Racing Line construction — engineered for high-performance and racing use where standard bearings fall short
  • Advanced bi-metal or tri-metal construction utilizing King's proprietary Aecular alloy overlay for superior wear resistance and conformability
  • Tight tolerances machined to exacting standards for consistent oil film thickness and reliable hydrodynamic lubrication
  • Standard (STD) sizing — designed for use with stock-diameter crankshaft journals requiring no crankshaft grinding
  • Full-set configuration — includes all main bearings required for a complete engine rebuild
  • Eccentricity and wall thickness consistency exceeding OEM specifications for improved load distribution
  • Compatible with General Motors 326, 350, 389, and 400 CID V8 engines

King Engine Bearings is an ISO-certified manufacturer with decades of OEM and aftermarket bearing production experience. The HP Series is a trusted choice among engine builders seeking a competition-grade bearing at a practical price point, offering enhanced fatigue strength and superior surface finish compared to standard replacement bearings.

Ordering went smooth!

i ordered on a weekend so there was an unexpected one day delay on the shipping, website did not update the shipping when i called shipping did not answer but emailing got a quick response and an appology, i ordered on a sunday 3/4/12 recived my hella supertone horns today 3/12 i kind of wished they put some bubble wrap or something inside the box that they shipped in tho. i installed them already and they work like a dream

Great price, I shopped around for hours on the web and no one could beat it, even with the shipping costed added in. The shipping was a little high, however, the price was so low it was still the best price around. Shipped in less the 48 hours. Thanks for a great deal and great experince.
