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.

Amazing blanket. Definitely recommend!!😊
Color: Tie-dye Sage, Size: Twin(60"x80")
Best blanket ever. I got it for an Amazon a lightning deal for 55% off! It was only 22 dollars and this is the most comfortable blankets ever. It is very soft and it keeps me very warm. I would definitely recommend it, it's even more beautiful in person. It's very high quality, and it's lightweight but keeps you warm. Though I wish they would lower the price, because it's 70 dollars to buy another one. But still an amazing blanket, 5 stars for me!!! 😊😊🥰🥰😍😍🤗🤗💗💞

Fabulous and sooooo soft
Color: Tie-dye Khaki, Size: Throw(50"x60"), Color: Tie-dye Khaki, Size: Throw(50"x60")
This blanket is so extremely soft and cozy. The only reason I deducted a star was because the fur side and the velvety side aren’t sew together anywhere besides the edges/seams, so when I fold it it’s basically like 2 blankets just sewn together and not one blanket. When you lie with it and cover you, they sort of separate if that makes sense but it doesn’t bother us. It’s so comfy to have on the couch and while movie watching. The only time it sort of a pain is when I fold it. In saying that, I would buy again. The velvety side is a soft tan/beige and the fur side is creams, off white and variations of the tan/beiges. So lovely. You can see it next to a solid cream colored blanket I have that I also bought on Amazon. It matches well and I love it!

This one is really soft
Color: Tie-dye Khaki, Size: Throw(50"x60")
This is actually baby bunny soft! I was very pleasantly surprised. The top side is plush and the bottom side is smooth but in a velvety suede type smooth. It is very well made and after machine washing and drying it several times it still looks and feels new.
