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 plot, steamy goodness, and absolute heartbreak, what more could you want?
Format: Paperback
“I’d already concluded a long time ago that I would never love someone the way I’d loved Wren—the way I still loved her. Because it didn’t matter if it had been ten days or ten years. A love like that ruined you for all others.” Suspenseful, Heartbreaking and Surprising! I have only read one other Catherine Cowles book; Tattered Stars and I loved it just as much as I love Whispers of You. The thing I love about this book (and the other) is also my one complaint. She has found the magic potion for a perfect romantic suspense. And maybe I wouldn't be saying this, if I had finished the other series, before starting this. I also know my opinion is so limited having only read two out of her incredibly extensive backlist. BUT the two I have read, feel very similar to each other, So much so that I look back now, a week after reading Whispers of You and I am getting them confused in my head. Thats not to say I didn't LOVE both books, because I absolutely did. This just felt like a plug and play equation to perfection with changing the details around. That being said this book grabs you from the prologue and doesn't give your heart a break until the very end. Holt and Wrens story is heartbreaking, I do wish we would have gotten a glimpse of the good before the bad, more often through the book to further the draw between them. But that's not because I feel like its lacking, its more that I loved the love these two had for each other and I would have enjoyed seeing it before either of them suffered through the tainted lenses of loss and fear. I loved the side characters and as the story progressed, I began to wonder who the culprit was, I did have one right but was dead nuts wrong on the other so both my mind was blown, and my heart was broken at the same time when I found out. Catherine Cowles keeps your heart in a vice the entire story and I love her for that. I am new to romantic suspense but am prone to panic attacks (HA) so, I find that her writing is just enough and not too much for me to read without sending me in to a tizzy. Overall though I do love this book, and I look forward to Echos of you and the second one in Tattered and Torn series, I just think I might finish that series before I keep going so, I can keep them straight.

Stunning Second Chance Romance
Format: Paperback
Well, I truly began my February reading in the best way with this book. I was so excited to read it after absolutely loving the Tattered and Torn series and it DELIVERED my friends. It has all of the emotions, all of the beauty, all of the suspense I’ve come to adore in Catherine’s books turned up even just a little more. Dare I say she even turned up the spice a bit?? Phew with the heat between these two! Along with the suspense element we get served small town, an over protective hero, and the most heart melting of second chance romances. Right from the prologue this book is off and running, I was not prepared for it. You meet Wren and hear about her gorgeous love for Holt. An absolutely horrific event occurs though that we learn sends him running for 10 years, and makes her a ghost of her former self after losing him. Neither of them, especially Holt, handled the aftermath well. It made me love them more though to see the growth they go through when he comes back and they reforge their intense, soul deep connection. Both of them face a whole lot of demons. I also love that even though it was completely awful for them both to be apart, Holt leaving forces Wren to become independent and stand on her own. So their second time around, it’s an even stronger, more equal relationship. If you follow my feed closely, you also know that I am always gone for a found family dynamic, and we have that here in spades with the way the Hartleys watch out for Wren. Her relationship with Holt’s parents and siblings is just gorgeous. The way Holt heals his relationship with them all is wonderful too. I’m already deeply in love with Nash and cannot WAIT for his book next. Yes to a new family saga series, please and thank you!!! I can’t recommend this one enough.

Definitely reading more by this author!!!
Format: Paperback
I really enjoyed this book! I absolutely love Holt and Wren. I loved watching them come back together and admit their feelings for each other. What I loved most was the mystery and suspension all throughout this book! It had me hooked from the very beginning, and just when I thought I knew who the culprit was, it was twisted to someone I never expected! I’ll definitely be reading more by this author 🫶🏻
