Carrying on a tradition of durability and dependability, KING Bi-Metal (aluminum) engine bearings feature 100% lead-free aluminum silicon.

King has 4 different variations of their aluminum based bearings:

(AM-Series) K-783 -Standard aluminum based material, equivalent to SAE-783, used for low and medium load engines.

King AM-Series main and rod bearings are recommended for street or marine applications. They have superior embeddability, which provides greater macro-particle and reduces scratching of the crank journals and tearing or weakening of the Babbitt overlays. The direct replacements feature tolerance control up to +/- .0001—and they're lead-free, making them environmentally friendly and user-safe. Order the King AM-Series rod bearings in the application designed for proper fitment with your vehicle.

(SI-Series) K-788 -Aluminum based material, strengthen by 2.5-3% silicon, for medium load engines or nodular cast iron crankshafts.

King SI-Series main and rod bearings are recommended for OE applications. These replacement bearings are designed for aftermarket gasoline or diesel engine rebuilding—and performance engines with factory crankshafts. The bearings have an improved crankshaft finish for reducing microscopic ferrite peaks on improperly ground or polished nodular cast iron crankshafts. King SI-Series main and rod bearings feature improved oil clearance to reduce wear and increase engine life, which in turn reduces operating noise, vibration, and excess oil flow. Order the bearing set designed for fitment on your make and model.

(SM-Series) K-789 -Aluminum alloy bonding layer. The strongest aluminum based material. The alloy is strengthened by addition of Manganese and Chromium (Mn, Cr), Used for high load applications.

For high load and performance applications, King SM-Series main and rod bearings are the strongest aluminum-based material offered by King. The alloy is strengthened by the addition of manganese and chromium. SM-Series crankshaft main bearings feature a traditional steel-backing, aluminum bonding layer, and the aluminum bearing alloy. They are available for a wide variety of vehicle and engine applications.

(HP-Series) K-787 - King HP-Series rod bearings were developed mainly for drag race applications needing a material harder than the Babbitt top layer. These applications demanded a structure that could withstand high loads for short durations and still offer higher embeddability and compatibility. In response, King developed the HP-Series featuring the Alecular metal structure.

The HP-Series is also suited for many performance applications with nodular cast iron crankshafts, such as street, strip, and some levels of Circle Track racing.

HP-Series bearings are particularly suitable for the following cases:

  • When a tri-metal bearing's Babbitt overlay extrudes over the sides, migrates to one end, or is physically removed by the crankshaft
  • When the intermediate layer of a tri-metal bearing is exposed, damaging the crank journal and requiring expensive grinding or replacement
  • When contaminants enter the oil stream, scratching and damaging the crankshaft journals

Three tiered design makes it a winner
Color: Beige
This umbrella is extremely easy to setup. It is lightweight and because of the three tier design it adds beautiful features to your back yard.

No customer service for product under warranty
Color: Beige
loved this umbrella for the 4 months we used it. did a lot of research to find an umbrella that would stand up to New England "breezes" -- this one was advertised as wind resistant; bought in June 2025, seemed very sturdy, really nice-looking, used on our patio (installed in the base the recommended base) through the summer; stored indoors for the winter; brought back onto patio a couple weeks ago. On a day with average wind a couple weeks ago, the tilt mechanism broke. Umbrella did not fall over, a gust of wind just forced the tilt mechanism to snap. Spent a lot of time trying to fix it, but it's permanently broken. It's less than a year old so still under warranty, as stated in the materials they sent with the umbrella. Same materials list the email to contact if there are any problems with the product. Have emailed the company, twice now, asking for a refund or replacement. Radio silence. Don't buy this unless you're ok with throwing it away after four or five months of use and being ignored by customer service.

Third time in 10 years nerding out on an Amazon patio umbrella on a budget...
Color: Navy Blue, Color: Navy Blue
Color: Beautiful, but the fabric is thinner than other options that are only ~$10 more. Tilt mechanism: Major reason for my 3:5 stars. It's plastic with a metal fastener through the middle. We won't be tilting this umbrella in any wind gust situations over 5mph. The warnings on the stickers and in the instructions make it clear this is a limitation, but it's not mentioned in the listing details. Quality | Value for money: Overall very mid. This is a nice 3-tiered umbrella at a near rock-bottom budget price for that class. I have found other mystery brand umbrellas on Amazon that have lasted for 5+ years, albeit with some (in my opinion) acceptable fading and rust. This umbrella leans hard into plastic everywhere except the fasteners. The ribs and pole are almost as thin as a few layers of beer cans pressed together. At least at the 10' and up diameter, this umbrella requires you to install equally flimsy-feeling extensions in order to get to 10', full sail. Final thoughts: This time around I chose price + delivery speed over quality, and I have a hunch I will be getting what I paid for. I doubt this umbrella lasts for more than 2 to 3 years without UV treatments and a very solid, heavy base.

Excellent Value.
Color: Forest Green, Color: Forest Green
Excellent value. Well made. Assembles in a few minutes. Note that the tilt control is the single click type. You push a button on the support column and tilt the umbrella until it picks in place. Venting design is helpful in keeping umbrella from tipping over in moderate wind. Fabric is a light synthetic. We chose green which we like.

Love this umbrella!
Color: Lake Blue, Color: Lake Blue
I totally love my umbrella. The 10 foot size is perfect for the coverage I needed. The assembly was super easy. The Lake Blue color is more beautiful than the pictures displayed. UV coating is exactly what I need, after having skin cancer. It's also stable in light to moderate wind, thanks to the slits in each tiered layer, allowing wind to pass through. I've only had this umbrella a week, but am impressed at this point. It's much more cost effective than having either an awning or roof extension over my patio. $90 vs $8-20k! Highly recommended.
