Disclaimers
Ceramic based clutch discs intend to increase the holding capacity and durability of the clutch as opposed to an increased life expectancy. Using a ceramic based material for easy street driving may contribute to premature wear of the clutch kit due to the harsher engagement and because of the higher tendency to slip the clutch during street driving.

Using a clutch kit with an unsprung clutch disc on a stock or lightly modified power engine that is daily/street driven vehicle can break the rivets on the clutch disc hub. Unsprung clutch kits are not designed for daily/street use or any constant on/off engagement environment. This can be compared to running a marathon in sandals vs a proper running shoe. If you were to run the marathon in sandals, you have no cushion or comfort and can cause injuries or wear you down faster than using proper running shoes.

*Increase in holding capacity is rated in Crank Torque, not Wheel Torque

Academic / Thought-Provoking
Format: Paperback
They Were Her Property: White Women as Slave Owners in the American South is a powerful, eye-opening work that challenges long-held assumptions about slavery and gender in American history. Stephanie E. Jones-Rogers thoroughly dismantles the myth that white women were passive or marginal participants in the institution of slavery. Through meticulous research and extensive use of primary sources, including legal records, letters, and testimonies from formerly enslaved people—the book reveals that many white women were active, knowledgeable, and often brutal slave owners in their own right. What makes this book especially compelling is how it centers the voices and experiences of enslaved people to expose the economic, legal, and physical power white women wielded. Jones-Rogers shows that white women not only benefited from slavery but also enforced it, defended it, and used it to build wealth and social status. The writing is clear, authoritative, and accessible, making complex historical arguments understandable without oversimplifying them. This book is an essential read for anyone studying American history, slavery, race, or gender. It forces readers to confront uncomfortable truths and rethink narratives that have long softened or excused the role of white women in slavery. They Were Her Property is both academically rigorous and deeply impactful—a necessary contribution to honest historical understanding.

Remarkable analysis of slaveholding women in Antebellum America
Format: Paperback
Stephanie Jones-Rogers has provided us with a book that looks at the South's "peculiar institution" through a very different lens - the slaveholders/slaveowners, but this analysis looks at women that owned slaves, thus opening up a new avenue of study that I hadn't previously seen. Jones-Rogers offers a well written account that is rich in historical details. She demonstrates through vivid historical evidence that the women that owned enslaved people were primarily driven by economic motives, and that these women were just as demanding and could be just as harsh as the "typical" slaveowner image that has been crafted over the years. The book is organized thematically, and each chapter demonstrates the economic motivation behind slave ownership. The reader is offered views of everything from young children becoming slave owners when their parents "gifted" them an enslaved person, and how these young girls were taught that this was "property" that could be used as desired to how these female slaveholders would sell their slaves to meet their economic goals. All told, this is a fascinating book that uncovers a long ignored slice of Antebellum American history that makes the historiographical literature of pre-Civil War history much richer.

Poignant, truthful look at women as powerful, business-savvy, yet brutal slave owners
Format: Paperback
Women slave owners were the norm in the South, not the exception. They increased in numbers, stature, and power while the men were off fighting the Civil War. Women often owned the slaves, not the men and knew how to sign prenuptial agreements back then to insure they kept all their property (including slaves) upon divorce or death of their spouse. They traded and bought and sold slaves with business savvy that most men envied. And they could be just as brutal towards their slaves. Ironically, it was the ownership of other people that empowered these women to not be bound to their husbands.

Good history, but not fun, engaging in popular literature.
Format: Paperback
The author is a very competent historian, and proves her points. She does so by stating each thesis and then reciting an exceedingly long string of supporting examples. Rinse and repeat. This is high quality, academic style history, but it’s not very engaging as popular literature. No one’s going to say “I couldn’t put it down.” That being said - I liked it! I learned a lot. Thanks.

Should be required
Format: Paperback
In my opinion, this book should be required reading in high school/college history classes. It’s so important to learn accurate history when it comes to slavery and this book does that. White women played a larger role than we are taught. Please give this a read!
