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 patented 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.

Great!!
Format: Hardcover
Want to know the back story behind Christmas? Rick Renner is a scholar and pastor extraordinaire! He delves into the Greek and highlights many details that you may have passed over in scripture! This is a wonderful read, the artistry is beautiful and he has written a back story for Easter also if you love this one. You will not regret getting this book!

Absolutely The Best Christmas Story Told!
Format: Hardcover
This book will forever be cherished and pasted on to my grandchildren. With all the wonderful illustrations and information that I have never known before. I am going to continue to be reading this book over and over because I love the opportunity of learning about Jesus with facts of history from an author who has done the research. I am planning on purchasing more to give as gifts.

CHRISTMAS
Format: Hardcover
EXCELLENT BOOK, I listened to Rick Renner on a program several months back and try to catch him everytime he is being interviewed. His other book about Noah and the flood, it too is so enlightening and opens these stories up to historical accuracy.
