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.

High Quality and Smells Great!
This is so far superior to the standard soaps that you buy off the shelf in a supermarket. It creates a truly luxurious lather and smells fantastic without being obnoxious or perfume.

Best vanilla body wash I've seen
Proper vanilla scent with a kick, without the vomit inducing synthetic aftertaste

Soap bar
Style: Vintage Suede, Size: 5 Ounce (Pack of 1)
A solid exfoliating bar that gives you a deep clean without being too harsh. The grit is just enough to remove dead skin and smooth things out, while the Vintage Suede scent adds a warm, slightly masculine fragrance that feels elevated but not overpowering. It lathers well and leaves your skin feeling clean—not stripped. ✔ Gentle exfoliation (not too rough) ✔ Warm, clean scent ✔ Good lather + smooth finish ❗ Can feel slightly drying on very sensitive skin ❗ Scent doesn’t last super long 👉 Bottom line: A great everyday exfoliating soap perfect if you want smoother skin and a clean, subtle scent without anything too harsh.

Another great product from Cremo!
Style: Vintage Suede, Size: 5 Ounce (Pack of 1)
I find myself buying from this brand frequently. It started with the body wash, then a shaving razor and now this product. Everything i buy from Cremo is absolutely miles ahead of national brands. When I saw this ant it was available in Vintage Suede scent, I had to buy it. Again, I was blown away by the quality of this product. It provides a rich, luxurious lather that cleans all of your troubles away. It's smooth and feels good. This has changed my morning shower into Shower 2.0. I also love that this is a minority owned business. I know that when I buy from them, the money goes to support real people, not some corporate fat-cat. Anyway, every Cremo product I have tried so far has been nothing short of amazing, and this is no exception. I will continue looking for more of their products I dont know about and trying those as well. Thanks Cremo! You knocked it off of the reservation again with this product!

Scrubby
Style: Italian Bergamot, Size: 5 Ounce (Pack of 1)
I love that the pieces in it feel almost like it's exfoliating. It lathers well, and my skin feels clean after. The smell doesn't cling or feel cheap, it's a well rounded shuttle fragrance. Although my skin loves it, my daughter says her skin gets aittle dried out but she puts lotion in and it's fine. I have been buying this for months now, and encourage you to give this a try. Would also make a great addition to a gift basket.
