Product Details

The King Engine Bearings MB605XP.026 is a complete crankshaft main bearing set designed for Audi and Volkswagen 2.3L and 2.5L 5-cylinder engines with engine codes AAB, AEU, APL, AAF, NG, RT, and JS. This set includes 6 main bearing shells machined to a .026mm oversize for use with reground crankshafts.

These bearings are part of King's XP (Xtreme Performance) Tri-Metal Racing Series — a line engineered with advanced metallurgical and geometric technologies built to withstand extreme performance loads. The XP series was developed specifically for high-load, long-duration applications that utilize forged steel crankshafts, including circle track, drag racing, off-road, and off-shore racing.

Key Features:

  • Tri-Metal Lead Bronze Construction: XP material features a lead bronze intermediate layer with a nano-scaled hardening process on the Babbitt overlay, rated to withstand up to 10,200 PSI load
  • pMax Black™ Overlay: A unique tri-metal structure that is 24% harder than conventional tri-metal race bearings for superior fatigue resistance
  • Bull's Eye Tolerance: Wall thickness tolerance held to ±0.0001 in. — the tightest in the industry — for consistent, precise fitment from shell to shell
  • Improved Oiling: Enlarged, chamfered oil holes with medium eccentricity for optimum load distribution and enhanced oil film maintenance
  • Narrowed Design: Mains are narrowed to accommodate large-radius crankshafts
  • Size: .026mm oversize for use with reground crankshaft journals
  • Set Includes: 6 main bearing shells

King Engine Bearings has been a trusted name in precision engine bearings since 1960, supplying the aviation, motorsport, and automotive aftermarket industries worldwide. The MB605XP.026 is the ideal choice for engine rebuilds and high-performance builds on Audi/VW 5-cylinder platforms requiring a reground crankshaft oversize.

So simple to shop with AUTOPLICITY. GREAT customer service when I called for assistance.

Shipped very quickly! I will be ordering more often!

very easy search and purchase. hope the part arrives and and is what I need

Great site. Easy to navigate. Shipping prices are superb.

So far so good. Everything was easy. I picked my car using your site and ordered the part needed. I hope I receive the part fast as well. **Update** Wrong parts were sent and after contacting customer service I requested to send the wrong part back in exchange for the correct ones but was told that they were out of the correct part and to keep the wrong part. There was no need to return wrong parts. I am torn in my rating because I needed the correct part but Autoplicity did everything they could and I have since ordered from a different site. Thanks.

Made a hard to find part easy.When I received the part it looked like a return from the tape job on the box. Part looked new but handled in an attempted install way of appearance. I'm sure it'll be fine.

The Westin T-Max winch cover seems to be of good quality and it fit my off brand winch. It would be nice if it came with the bindings though. Good product.
