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.

Sleek, Sturdy, and Easy to Assemble: Zinus Kai Platform Bed Frame Review
Size: Full, Style: Kai
The Zinus Kai Bamboo and Metal Platform Bed Frame with Headboard was a solid choice for upgrading my bedroom. The assembly was straightforward once I sorted out the parts (always a little organizing required), and the tools needed for the setup are included in the box. It took me about an hour to get everything together, and the instructions were clear enough for a hassle-free process. Once assembled, the frame isn’t overly heavy, which makes it easy to move around, especially with the helpful sliders. The final look of the bed is sleek and modern, with the bamboo accents giving it a classy and natural touch that fits perfectly with various bedroom decors. The under-bed clearance is one of my favorite features—there’s plenty of space for bins and storage, which helps maximize room in the bedroom. As someone who’s on the heavier side, I really appreciate the platform bed’s solid support. It offers excellent stability and has completely eliminated the creaking and sagging I’ve had with other frames. It’s a sturdy base, and the support bars provide a reassuring level of durability. Final Thoughts Overall, I’m very happy with the Zinus Kai Platform Bed Frame. It’s easy to assemble, looks great, and offers great support, especially for those who need a little extra stability. The under-bed clearance is an added bonus for storage, and the design gives a clean, modern look. For the price, it’s a fantastic value, and I’d recommend it to anyone looking for an affordable, stylish, and reliable bed frame.

Really happy with this bed frame! The wood looks great, the white finish goes with everything, and it gives the room a clean modern look. It was easy to put together and looks even better in person. Great quality for the price!

CHOOSE a DIFFERENT Bed Frame!!!!
Size: Queen, Color: Walnut
Please choose a different bed frame. My partner and I built this today together and it took way longer than we thought it was going to because the instructions were so horrible. Some of the parts were also very flimsy. It looks good once done but it’s not worth it. I wish I had picked something else. Not to mention one of the wood pieces already was cracked when we opened the box.

Love this bedframe!
Size: Queen, Color: Walnut
Delivered earlier promised! :) Went easily together, the directions were spot-on! No need for a boxspring, but if you have one? It just makes the bed a bit higher. Just the style per the picture
