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.

Best Pillow Ever
Size: Queen(Pack of 2)
I am absolutely obsessed with these pillows! They have the perfect balance of firmness and softness, providing amazing support for my head and neck. I've never slept better, and I can honestly say I'd order more in a heartbeat. These pillows are a game-changer for my sleep quality. I highly recommend them to anyone looking for the ultimate comfort.

Worth it!
Size: Queen(Pack of 2)
These pillows are amazing and very soft and comfortable. They came nicely packaged and I let them sit out for just a few hours before using them and that was plenty of time! They come with the cooling cover and fit a standard queen sized pillowcase. The material expands well and does not have any weird smells. 10/10 well worth the price.

Miracle pillow
Size: Standard(Pack of 2)
Best pillow Iβve ever had. I have been using this since December 2024 and it still hasnβt gotten flat. It is amazingly comfortable and solves all my neck issues for a side sleeper. My head never gets hot either. Iβve recommended this to my friends and theyβve had success with it as well.

Really wanted to love these
Size: Queen(Pack of 2)
I really wanted to love these but they gave me a stiff neck. I haven't slept with a pillow since buying these. They are firm except where you lay your head. It just deflates there. I expected it to sink in to match the curve of my neck but it was more than I could handle. My head ended up in a valley between the two ends of the pillow. The price was good, zipper worked fine, it looks as advertised and the pillows are good quality. The cooling part works, its just not what I needed.
