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.

More cinnamon flavor than vanilla
I really wanted to like this lip balm but, as another person commented, the cinnamon flavor dominates. It does moisturize quite well if you can overlook how spicy the cinnamon tastes. Would have preferred just plain vanilla instead. Not sure I'll keep this.

hot cinnamon
Only had this one day and I do like it but would like to note the cinnamon is more like hot tamale cinnamon not cinnamon roll cinnamon. still does the job but my chapped lips give a good burn for maybe 30 sec :( going to check if they have another flavor option for next order

Best lip balm I’ve found yet
Every lip balm or chapstick I have ever used has always bothered my lips and made them peel. I’ve tried cheap chapsticks to organic chapsticks to vegan and nothing has ever worked. I figured I’d give this a try since I didn’t have much to lose and I am SO glad I did. This is the first lip balm that hasn’t made my lips peel. I LOVE THIS. And the cinnamon vanilla smells divine. This is definitely going to be my go to from now on.

LIP GOO GOOD ENOUGH FOR EDS PATIENTS!!! I have old school type3, the super bad…
First of all… I used to have a desserts catering side hustle and my oatmeal scotchie recipe starts smelling EXACTLY like this combo!!! I am 51 and have tried LITERALLY THOUSANDS of chapstick type lip goos, I have a genetic disorder that prevents me from being able to absorb anything… most to all chapsticks DO NOT WORK but my lips are currently soft… it actually feels amazing to have something on my lips that seems to work!!! Instead on sitting on my lips or skin all weird and greasy til I freak out rub everything off!!! It’s working… NOT SOMETHING I WAS ACTUALLY WILLING TO ADMIT TO… My VEGAN MOTHER talked me into trying this, she’s more absorbent and can use other products, I cannot, however!!! I seriously LOVE THIS GOO!!!

you won’t regret it
absolute life saver on a winter trip to austria, and has become my go-to every day since! even before my trip i was struggling with chapped lips and this healed them and protected them through winter sports better than anything i’ve ever used, and i’m a lip balm snob. smells amazing, feels amazing. 10/10!
