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.

NICE BAG
Color: A Black
Beautiful bag, exactly like it appears in the picture. I’ve been using it for months, and it still looks as good as when it arrived. It had a slight odor at first, but that disappeared after two days. I like the fit, the durability, the pocket inside the bag, and the small bag. Great purchase for the money I spent.

I just received my new purse. It is so soft and spacious. I love the extra pouch. It’s really nice to throw across your shoulder and run a few errands. Great purse for the price.

Enough space and nice look
Color: Dark Coffee
So far is good. I bought it to go to work . It's not leather and it may not last many years, but for me it's fine. I can locked it in my file cabinet because it flexible and soft.
