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

These are real nice looking industrial look, but bear in mind, they don't come with the shelves
First, understand that you only get the structure, not the actual shelves. The structure is decorative, industrial. piping, which looks really cool., especially in my utility room. I'm gonna get some hardwood for the shelving, so I don't have a picture yet, but I will as soon as I get that. The frame is very stable and strong. So thumbs up on the stability, structure and quality. The directions are straightforward, and all the parts are there. It looks real nice in my utility room and will look real cool when I've got the shelving on there. It's definitely a good value for your money if you need more storage shelving.

Perfect companion to other HBLYJS bracket systems — great aesthetic, versatility and functionality
I’m already a fan of the HBLYJS wall bracket system that I used in my daughter’s room, so I wanted to try this floor-to-ceiling option from the same brand for a slightly different look. The two coordinate perfectly — same black iron finish, same industrial-farmhouse aesthetic — and provided nice cohesion. What makes this system stand out is the flexibility in how you mount it. You can rest the uprights on the floor or hang them from the ceiling depending on your space and what works best structurally. That's a rare option and makes it easy to fit into rooms where a standard wall-mount wouldn't work as cleanly. I chose to hang them from the ceiling, because I personally love that look. Just make sure you mount these into studs! Like the bracket set, planks aren't included, but picking your own wood lets you match stain color and cut boards to the exact length you need. The heavy-duty pipe construction feels solid and the vertical design makes great use of wall space without eating into floor space. I definitely recommend the HBLYJS wall bracket systems for the great aesthetic, storage, versatility and functionality they provide. I will likely be buying a few more sets soon.

HBLYJS Industrial Pipe Shelving System
This shelving system gave my room a cool industrial look. The metal brackets feel heavy-duty and very stable. Installation took a little time but wasn’t difficult. I like that I can choose my own wood planks for customization. It holds a good amount of weight without sagging. The black iron finish looks great against the wall. This was a solid DIY upgrade for my space.
