XP Tri - Metal Racing Series

<スパンstyle="font-family:arial,helvetica,sans-serif">Successful racing engine builders are constantly pushing the limits of load capacity to new levels. Today's racing bearings inevitably need to meet these demands with more competitive bearings. At King Racing, we have tackled this challenge with the XP high-performance bearing series.

Features:

  • <スパンstyle="color:#000000">High-load/long-duration racetracks such as circle tracks, off-road, offshore, and other applications requiring steel crankshafts
  • Enhanced tri-metal copper-lead structure with nickel barrier and SecureBond adhesion< /span>
  • 15% to 30% higher load capacity than conventional bearings
  • SecureBond proprietary adhesion process for superior stability between the top and intermediate layers
  • 0.0005" metallurgically enhanced and hardened performance overlay to withstand greater loads and provide increased resistance to surface fatigue
  • Mains with 1/2 groove for uncompromising lower shell load capacity

Please note: Images are for display purposes only and may not reflect the actual product.

The XP series is a line of bearings featuring advanced metallurgical and geometric technology to handle extreme performance loads. It was developed for all performance applications using aftermarket forged steel crankshafts that experience high loads over long periods.

King Racing's XP series features pMax Black, a unique tri-metal structure that is 24% harder than other conventional tri-metal racing bearings. The combination of pMax Black and the XP’s geometric features is ideal for performance racing.


Before ordering

At the Shafutoya shopping site, we pay the import consumption tax incurred at the time of import on your behalf, so there will be no additional charges beyond the total amount paid at checkout.

If you order without verifying compatibility, we cannot accept returns due to incompatibility.
Please note that even if items are sorted by selecting the year, make, and model on our homepage tabs, this does not guarantee a direct fit for Japanese market vehicles without modification.
All products have been translated into Japanese using translation software. Due to potential confusing phrasing, please contact us before ordering if you have any questions.

○ Regarding Shipping
Shipping costs are paid at the time of checkout. Shipping estimates are calculated automatically once you enter your shipping address on the checkout page. For large items such as body parts, the actual shipping cost may occasionally differ significantly from the automated calculation. In such cases, we will contact you individually via email.

In principle, all products are shipped internationally from our U.S. warehouse. Unlike domestic shipping in Japan, international shipping takes approximately 7 to 14 days, so please allow sufficient time for your order.

○ Regarding Japanese Vehicle Inspection Compliance
Products handled by our company are fundamentally designed and manufactured outside of Japan.

Therefore, all parts are sold for the purpose of "use on circuits, private property, or off-road," and installation and use are at your own risk.

○ Regarding Warranty
Please inspect the contents immediately upon arrival. Since all products are shipped internationally from outside Japan, there may be instances of shipping damage to the packaging or the product.
