Red Line Synthetic ShockProof™ Gear Oil provides unequalled protection for high performance differentials and transmissions which are heavily loaded or which see shock loading. This revolutionary lubricant is completely different from conventional lubricant technology in several ways. The viscosity characteristics are significantly improved. Gear teeth need high viscosity at high temperatures to prevent metal to metal contact and a low viscosity when cold to reduce fluid friction. The ShockProof™ chemistry significantly reduces the thinning effect of high temperatures. The Heavy can be rated as a 75W250 Gear Oil, but has the lower internal fluid friction of an SAE 75W90. The Lightweight can be rated as a 75W140 Gear Oil, but has the lower internal fluid friction of an SAE 30 motor oil. The SuperLight can be rated as a 70W90 Gear Oil, but has the lower internal fluid friction of an Automatic Transmission Fluid. These ShockProof™ lubricants provide much greater viscosity in the thin layers between the gear teeth, but have very low internal fluid friction, which means very little power loss for the protection achieved. ShockProof™ Gear Oil has a 40 Percent lower coefficient of friction and 250 Percent the load carrying capacity compared to conventional gear oils, which means that metal to metal friction is greatly reduced. Temperature reductions between 25 to 75 Degree Fahrenheit are common in circle track, road racing, and off-road racing. Improved durability in high performance use is the primary benefit of the Heavy ShockProof™ and along with the improved durability is an improvement in efficiency, but if further improvements in efficiency are desired, and durability is not a major concern, Lightweight and SuperLight ShockProof™ can be used. Red Line ShockProof™ can be used in conventional, limited slip, or locker differentials. Red Line ShockProof™ is designed for use in competition differentials and transmissions.

Editing and Hockey Research Would Have Made This Better
Format: Kindle, Format: Kindle
A bit of editing and research needed here. Maybe I’m just a hockey fan, but if you’re going to use actual NHL teams as opponents, please make sure you use actual NHL teams and not NBA team names. At the beginning of chapter 24, they play the “Philadelphia 76ers” which is NOT Philly’s NHL team. That’s an insult to Gritty and the Flyers, Philly’s actual NHL team. Honestly, if you’re going to use a fictional NHL team, them
just make all the opponent teams fictional too.
Additionally, I believe that trainers have an entire area to themselves, not just an office with one or two tables. June wouldn’t have to go through the locker room to tear the players; more likely she has her own space and office area. war the workout and recovery areas.

So So Amazing
Format: Kindle
I received this book wiht the understanding that I could leave a voluntary and honest review.
In this book we meet June Wilder, Rhett Lawson, Cole Thibault, & Elias Nystrom. When this book opens we find that June has just joined the Atlanta Reapers as their new physical trainer. From the moment she starts she knows that she is going to get push back but there is something about not only this team but these guys that have become more to her than she thought when she first started. Rhett is the kind of guy who make a joke with anyone. One night when something happens with June he realizes there is something more than just jokes with her. Cole has been compartmentalized his life for years now. With the addition of June to the team he finds himself finding a person who understands his compartments and lets him be him. Elias is a man who is a an island. When he learns that opening up to one person who sees him allows him to grow and heal in many ways. Can they all find a HEA or will their positions make that impossible?
Another amazing story by this author. I would highly recommend it to anyone.

Good spicy campy hockey
Format: Kindle
I really enjoyed the character development. Reading about their growth and dealing with individual issues made good entertainment. Some surprising twists that made the book even better. Really glad we didn't have to go down the angst road where the public got to damage the budding relationships.

Great read!
Format: Kindle
Wonderful characters with great humor, a bit of mystery and a strong silent grumpy Sentinel to stand with the leading lady. They make her stronger but she also makes them stronger. I love the dynamics and the way it played out. This was a fun read!.
