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

Great Looking Shelf
Color: Brown, Size: 4Tier48in, Color: Brown, Size: 4Tier48in
I love this shelf! It took two people to hang it and you definitely want to ensure you hit a stud on at least one side or 1-2 screws if mounting between studs. It is heavy but a single person can lift it, just not maneuver easily due to its dimensions. It has a ton of room and fits mini helmets nicely in my office. Where I mounted it made it difficult to an extent to install but if you are even somewhat handy, you’ll be fine. You absolutely need a stud finder to hang this shelf. Sorry, I’m married! I would buy this shelf, or versions of it, again. Very practical and useful to display autographs, housewares or decor. Last note: do not over tighten the poles. The wood is soft and the poles are light weight. They are not traditional black pipe and weigh far less.

AWESOME Look and Quality
Color: Brown, Size: 2Tier60in
I love these shelves and have bought additional for other areas in the house. I love the look of the industrial pipes, the color of the shelves is perfect, they are sturdy and hold a lot of weight. They are somewhat difficult to assemble, but it's expected as hanging shelves are never fun to hang. I love them. If you are on the fence, just do it :)

Nice, but a bear to install
Color: Black, Size: 3Tier48in
Quality product that looks good on our shiplap wall of the wet bar space. The install was a real trip and extremely difficult. You definitely need 2 or more people to install as the direction tell you to put the entire item together, then hang on the wall. This makes it impossible to do yourself.

Exactly what I was looking for
Color: Brown, Size: 3Tier48in, Color: Brown, Size: 3Tier48in
Very sturdy shelves and super easy to put together. I would put the shelves together starting with the bottoms then after it’s put together tighten everything up also starting from the bottom.
