Today’s sport compact race engines make more power than ever before. Yesterday’s engine bearings’ load capacity no longer works for today’s sport compact race engines. Tomorrow’s engines will be even more powerful.

King bearings meet these demands with higher performance benchmarks, advanced materials and unique geometrical features.
King Racing’s SV, GPC, XP, and XPC series of rod and main bearings were developed to meet these challenges through technologically advanced geometrical features and a unique metal structures. Together, they drive the industry to a higher level of durability, performance and expectation.

pMax Black is a unique tri-metal structure the has been developed to meet the ongoing demand for bearings with increased load capacity. As engines evolve and gain more power, engine bearings have to be able to handle the extra loading.

pMax Black consists of three layers that come together to form the strongest tri-metal bearing in the industry with load capacity exceeding the competition by as much as 24%. King Racing’s new hardening technology modifies the overlay molecular structure and creates a fatigue resisting shield.

The intermediate layer of a typical race bearing contains 2-3% tin, with hardness values of 90-95 HV. For a superior pMax Black intermediate layer, we increased the tin content to 4.5%, making it 22% harder (115 HV), with a load carrying capacity of 17,000 psi.

The overlay of a typical high performance bearing consists of a leaded alloy that contains 2-3% copper. It achieves a hardness level of 11 – 14 HV, and a maximum load capacity of 8,000-8,500 psi. King’s pMaxBlack overlay is significantly stronger than conventional overlays due to its 5% copper content and an innovative nano-scaled hardening process.

The pMaxBlack overlay contains 5% copper. It is further strengthened by a proprietary nano-scaled hardening process that modifies the molecular structure and creates a black fatigue-resistant shield. The outcome is a significant 29% increase in overlay hardness (18.1HV) and overall 24% increase in load capacity (10,200 psi).

SecureBond – Maximum tri-metal structural integrity

High loads and high RPM’s create critical stresses that travel through the multi-layer construction of a tri-metal race bearing. SecureBond is a micro-etch surface preparation process that strengthens the tri-metal structural integrity. SecureBond reduces the likelihood of catastrophic failure due to delamination of one layer from the other under extreme load conditions or metal–to-metal contact.

Bright color easy to see but not a great bounce on the outdoor court
Style: 6 - Pack, Color: Pink
I liked the fact that these balls were a bright color and easy to see but the bounce on them was not as good as other name brands. They were OK as a back-up and performed better outside then on the indoor courts which are made of a different surface. We are using them , but would most likely not repurchase.

Price was best I found for quantity anywhere
Style: 6 - Pack, Color: Purple
I am a beginner and by no means an expert, but these balls appear to be as any other. The couple at the next court had a Franklin ball that came our way, and I bounced it and popped it back - I couldn't tell any difference in that instance. Sports stores had just one color - yellow (maybe one had chartreuse) amazon has single colors multiple - I thought it was worth this purchase. The purple may be harder to see on cloudy days - as I had on sunglasses and I could see it, but the fence at the court has a "privacy" net, it kinda bleneded in for a very brief moment until the sound was heard of the return, then no problem.

Great Balls!
Style: 6 - Pack, Color: Purple
Great Outdoor balls. These are correct weight at 0.85oz and with 40 holes for outdoor play, not indoor as some other reviewers claim.

NOT Outdoor balls.
Style: 6 - Pack, Color: White
NOT outdoor. Don't waste your time if you are looking for proper outdoor balls, these are indoor. I don't play indoor so couldn't use them.
