King Racing Main Bearings - XP Tri-Metal: Successful race engine builders are constantly pushing the limits of load capacity to new levels. Race bearings today inevitably need to match these demands with more competitive bearings. At King Racing we met the challenge with the XP high performance bearings series.The XP series is a line of bearings with advanced metallurgical and geometric technologies that meet extreme performance loads. It was developed for all performance applications that use forged steel aftermarket crankshafts and produce high loads for extended periods.
King Racing's XP series features pMax Black , a unique tri-metal structure that is 24% harder than any other conventional tri-metal race bearing. pMax Black together with the XP geometric features are the ideal combination for performance racing. For more on King Racing technologies visit TechLab
All King Bearings are specifically engineered to withstand the highest loads and RPMs generated by today's top competition engines. All King Performance Engine Bearings feature:
* * Bull's Eye Tolerance *. King engine bearings have the closest wall tolerances in the industry, with all shells matched to 0.0001".
* *Increased Height.* Greater rod bearing height improves bearing-to-bore contact/heat transfer and reduces spin potential at high RPM.
* *Improved Oiling.* Mains feature enlarged, chamfered oil holes.
* *Medium Eccentricity.* This enables optimum load distribution and improved oiling.
* *Dowel Holes.* Most rod bearings are available with or without dowel holes.
* *Narrowed Design.* Mains and rods are narrowed for large-radius crankshafts.
We offer the industry's widest selection of sizes, including special clearance options. With more choices than ever, you'll find the right King High Performance Engine Bearings for your most demanding applications.

Don’t buy for restaurant industry
Size: 10.5, Color: Black, Size: 10.5, Color: Black
Good looking shoes, fairly comfortable and good value based on the description shared, so I don’t feel it’s fair to rate them lower than 4 stars. I had high hopes for them based on previous reviews from others saying they wore them in the food and beverage industry that mentioned their quality and durability, however I strongly recommend looking elsewhere if you do. I purchased these to wear working in a full service upscale restaurant and in less than two months have managed to have torn the material on the middle exterior section and the bottoms of the shoes are already completely worn down. Good design, but the durability needs to be improved if they’re to hold up for that industry.

DO NOT BUY (lasted less than 7 months)
Size: 11, Color: Black, Size: 11, Color: Black
I bought these for work as a bartender in August of 2025. By December, the tops were scuffed, frayed, and peeling beyond repair, and by February, the soles were coming off. I’ve never had a pair of shoes with such low quality.

Most comfortable shoes, right out of the box!
Size: 8.5, Color: Cognac Napa Leather
Oh my! So, my ordering of shoes online has been hit or miss - 1/2 size too big or too small; too wide or not wide enough. Enter these Marc Joseph shoes… such a game changer. They fit like a glove, exceptionally comfortable, and easy to slip in and out of. I like them so much that I am shopping for another pair. So far, the size, quality, fit, feel, look, and comfort make this pair my dedicated first pick. Btw, I have been wearing them for six hours and they are still very comfortable! I highly recommend these shoes.
