Wavetrac diffs are state-of-the-art helical gear differentials designed, developed, and manufactured in the USA by Autotech Driveline. The Wavetrac Audi A4 & S4 Quattro 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 rear differentials include a transferable, Limited Lifetime Warranty.
*Includes bearing spacer for small end side of the differential, only needed on some models

Great shelves at an even better price
Color: Brown, Size: 15.7in, Color: Brown, Size: 15.7in
These shelves are great quality. Easy to hang and come with all the hardware you need. No matter what type of wall you are hanging them on. Saved me a bunch of space. Gave me a place to place some of my books without having to take up floor space with a bookshelf. Light weight material with a durable quality. Stable for lots of things. Fits my space needs

Beautiful shelves upscaled my living room
Color: Brown, Size: 35.5in
Love these! They are pretty and look expensive on my walls. I like them so much I bought a second set for my bedroom.
I used these in a corner to create a gallery wall effect and it’s beautiful.
They were super easy to put up, they are very light weight and I’m not sure how much they can hold when properly installed but they seem to be able to be stable and carry a decent amount of weight as mine are used as a gallery wall and are holding tons of photo frames. These aren’t adjustable once they are up so be sure about where you want them placed, they definitely upscaled my living room and decluttered my walls. I get tons of compliments when I have guests!

Very nice shelves
Color: Black, Size: 15.7in
These shelves look so good. I used them to hold my pop figures and it put together my room very nicely. It was good for the price as well with how many it came with and the quality of the shelves. If you need more space then you can put the shelves together side by side to have more room.
