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.

Sturdy umbrella base
It’s really nice and sturdy umbrella base with wheels. The wheels make it easier to move wherever you want. Very easy to set up.

Exactly what I was looking for
These are exactly what I needed. I like the fact that you fill them with water so at the end of the season, I just emptied them and take them to my shed for storage. I also like that they have wheels on the bottom that rolls my umbrella around anywhere. They’re well with the money.
