Merchant Transfer Case Pump Upgrade
The GM transfer case use a gear pump inside the case that is driven off the mainshaft. This pump forces oil to the planetary as well as the drive sprocket sleeve. The 5 tabs around the housing fit into the spots in the rear housing are what positions the pump. Over time, the pump can start to wear on the rear housing. This is commonly referred to as pump rub. Each transfer case includes the Merchant Automotive Pump Upgrade to alleviate these "Pump Rub" issues.

Women’s fit!
Size: One Size, Color: Black/White/3, Size: One Size, Color: Black/White/3
This hat fits women’s heads ( mine is small) and is fully adjustable by the Velcro strap on the back. It is made out of light material that is great for a workout and has air holes / mesh for cooler wear. So eat to clean just pop in the washer and hang to dry! Doesn’t get stiff at all and retains its shape! Very well made & stylish in the black/ white color combination. Great for keeping the sun off your head, or just extra warmth!

Great hat for hot weather! Good for women with a small head!
Size: One Size, Color: Aurora Plum Purple/Powder Plum Purple/3, Size: One Size, Color: Aurora Plum Purple/Powder Plum Purple/3
This hat is super light weight, breathable and comfortable. It feels high quality and it looks cute. I wore it on a super humid day on a hike and my head felt a lot less sweaty than it does wearing a regular baseball cap. The color is pretty! I also have a problem with most unisex baseball hats being far too large and deep for my head. They usually come down over my ears, but this one fits me really well and doesn’t push my ears down. Definitely would consider buying it in another color.

Size: One Size, Color: White/Silver Metallic/3
The fit and color are really good. I was looking for a hat to cover my new short hair cut. Not too heavy so i can wear it in the sun.
