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. 10 BMW M12x1.5x24 bolts 33121205561 or 10 ARP bolts N.M12.150.24 required if performing your own welded ring gear service (already included with our "Install Kit").

Mock turtle neck sagged and did not fit well.
Shirt is well made. Collar not so much. Sagged and did not fit well. Donated to Goodwill.

A Difficult to Find T-Shirt
These T-Shirts are nice. A super difficult to find. The manufacturer calls it a mock-turtle neck (MTN). But the collar height is actually a bit shorter than the traditional MTN, which is great. It's closer to a regular T-Shirt that comes all the way to the neckline. And very somt a comfortable. This is the perfect style of T-Shirt to wear under a sportscoat, if desired. Or under a shirt where you want the T-Shirt to show for contrast. Just the right look.

Nice shirts for the price! But do not recommend for thick body types.
I bought 3 different ones. 2 Mediums and 1 2XL. The mediums fit correct and really nice! Would definitely recommend for the price! More like a exercise material, and sticks to your body shape... Sooo the 2Xl did not fit the person correct. Was so tight... And the strech is to stick to your body... So would not recommend for anyone a bit hefty or fit tbh. But the shirts are good materials and feel nice for a fresh day out or to use as gym clothes!!
