Porsche 915 Coarse Spline (18 tooth) - 911, 930 1975-1977
Wavetrac diffs are state-of-the-art helical gear differentials designed, developed, and manufactured in the USA by Autotech Driveline. The Wavetrac Differential is the only torque biasing differential on the market with patent-pending technology that mitigates wheelspin when an unloaded wheel condition arises. During zero axle load conditions, the Wavetrac cam device acts to create internal load, maintaining drive on the gripping wheel instead of acting like an open diff (and going nowhere!). Super strong 9310 alloy steel gears are enclosed in case-hardened steel bodies, held together with ARP fasteners. All Wavetrac differentials include a transferable, Limited Lifetime Warranty.
*Longer ring gear bolts required on some models
For 8T pinion, 31T ring

Ordered new, got it used
Format: Paperback
Paid for a new book. It arrived very clearly used. It is in decent condition but it is frustrating paying that much for something to arrive used with damage.

Great Read
Format: Hardcover
Have always loved John Mark Comer's voice and tone as an author. He breaks down heavy and emotional concepts in an easy to read and understand way backed by scripture.

Great book to read if you want to get married.
Format: Hardcover, Format: Hardcover
As someone who doesn't read a lot, I loved this book. The author did a great job keeping me engaged, and I appreciate his transparency. These topics aren't always talked about in Christian settings unless they're within the context of marriage. This book is perfect for someone who is single, dating, or in a relationship, and wants to get married.
