More Info:
AEM Tru-Time Adjustable Cam Gears increase horsepower and torque without having to change the camshafts and are must-have items for engines that are milled, forced induction, high compression and/or utilizing aftermarket competition cams.
AEM gears enable users to match cam timing with their vehicle's tuning state by advancing or retarding the cam profile in one-degree increments via true laser-etched markings.
Precision-cut gear teeth ensure no premature wearing of the belt surface and AEM's anodizing on the gear teeth is lab-test proven as the hardest anodizing process on the market.

Great fit and look
Size: Medium, Color: Grey
Husband loved it! Great fit and he said it was comfortable. Can be worn untucked or tucked in pants. He wore it with jeans and a blazer untucked for a graduation party and looked perfect for the occasion.

Tight in Chest for Broad Chested Men
Size: XX-Large, Color: Green
Quality is okay but not great. The biggest problem was the size. It was too tight for my broad chest. Ended up giving it away. I bought some similar shirts from a different supplier that I didn’t have issues with.

NOT SLIM FIT.
Size: Large, Color: White
NOT A SLIM FIT. Misleading. White is off-white, cream. Not neutral, bright white. Decent material. Ok quality. Textured, thin but not too thin. Dressy, not very casual.
