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

Fun light RomCom
Format: Paperback
Rating: ⭐️⭐️⭐️⭐️ 4/5 Spice rating: 🌶 1.5/5🥵 Read if you like the following tropes: • Enemies to Lovers           • Brother's best friend          • RomCom                  • Forced proximity.    "So tell me exactly what you're wearing" It has been WAY too long since I've read a RomCom and this was THE perfect book to remind me how much I missed them! I read this book in one day simply because I could not put it down or stop thinking about it. "Mr. Wrong number: I texted the wrong number, didn't I? Me: Yeah, you did :)" This was such a light, fun, quick read that had me laughing. "I'd gone from finding her the most annoying girl in the planet to being inexplicably obsessed with her. " Loved the duel POV and how because the two MC's know each other, you not only got 🔥 banter between Colin and Olivia but also between Mr. Wrong number and Misdial (2x the 🔥 banter??? SIGN ME UP🙋‍♀️) "She was the first thing I thought of when I woke up in the morning,  and the last thing before I feel asleep. I would blow off anything to be with her, because everything was brighter when Olivia was around. " I Loved Olivia's disastrous luck, her passion for writing and live in the moment spirit. And I Loved the whole plot and texting element to the story . The one character I couldn't stand was Olivia's mother🙄😡 ugh. IYKYK I look forward to reading more from Lynn Painter as I really enjoyed her writing style.

Disappointing with too much "sturm und drang".
Format: Kindle
I was disappointed after the joy of "Happily Never After". I found both characters unpleasant. I've known people like her who broke everything they touched, and had zero consideration other people's property. She always refused to accept responsibility. It was always "Not my fault", or blaming the victim for the valuable she just destroyed. She's not funny. She's not honest, and she's not appealing. And he is a bit of a door mat, letting his father say the most awful things and not setting him straight and walking away. It's a pity because the premise is good and frequently hilarious, but she's a walking, talking red flag.

Mr. Wrong Number & Ms. Miss Dial
Format: Kindle
Lynn Painter has quickly become my go-to rom-com author, and Mr. Wrong Number is pure fun from start to finish. A wrong-number text turns into a flirty, anonymous connection that’s impossible not to love. Olivia is messy and relatable, Colin is slow-burn perfection, and the banter is sharp, swoony, and totally addictive. If you love texting mishaps, flirty sparks, and romances that feel real, this one’s a must-read. 💕📱

One sitting read
Format: Kindle
I think I might have a thing for text message chains and love letters. This book is full of witty, sexy banter. My personal faves. Colin: What would you do if you accidentally texted the wrong person something naughty, and they responded in a way that surprised you? You were so intrigued that you kept coming back to this faceless number. She's sexy, straightforward, effortlessly funny, and you can't stop thinking about her. And then you realize this mystery woman is none other than your unwanted roommate and best friend's sister. She's a dumpster fire in real life, but what if there was more to it than that? Olivia: Who hasn't started an apartment complex on fire, lost their job, and forced to move back home and live with their brother and his insufferable best friend? Add in some mismatched socks, and this is a typical Tuesday night for Olivia. I devoured this book. I opened it thinking I would read a few chapters and fall asleep. 4 hours later, I finished it. IN.ONE.SITTING. The bags under my eyes today were worth it
