Wilwood’s Tandem Aluminum Master Cylinder is available in 2 bore sizes 1.00” and 1-1/8”; and 3 finishes, plain, ball burnished and black e-coat. 7/8” bore master cylinders are designed primarily for manual applications and include a pushrod. The 1” bore can be used in manual and power assisted applications and does not come with a pushrod. The 1-1/8” bore is designed for use primarily with power brake applications, either from vacuum assist or hydraulic assist systems. They’re designed for mount flanges from 3.22” to 3.40”, common measurements for most domestic cars and trucks from the mid 1960s to present, and offer fluid outlet ports on both sides of the bore. The stroke is set at 1.10” with a volume ratio of 2:1 between the primary and secondary chambers. Machined from high-pressure die castings, each master cylinder weighs only 3lbs, a 75% weight savings over most cast iron OE type master cylinders. We also offer a our combination proportioning valve kit, which includes brackets and stainless lines specifically for use with these master cylinders, see PN 260-13190, or 220-13189 for retrofit kit.

Great gift
It’s really hard to find a wallet with a mesh ID window. This one looks great and fits very well in the back pocket.

Herschel is seriously the Best!
Color: Black Tonal
Got this for my teenage son & it was the perfect size for him. He didn’t want a bulky wallet, just something simple to carry his school ID, cash and his debit card. Herschel has amazing quality products, definitely can’t go wrong with them! Worth the price for sure :)

Nice and thin
Color: Black Tonal
Slim wallet. Made for a minimalist type of person. Ideally for only about five cards and some cash anything more the wallet will start to bulge.

Minimal and Magnificent
Color: Black Tonal
I've had more than a few front pocket wallets, and this one is up at the top. It's sturdy even though it's thin, and the stitching is even. Card retention is great with room for 1-2 cards per pocket, as well as room for a few bills to fit comfortably in the middle pocket. Probably going to buy another as a backup.

Perfect size, style, and material
Color: Ivy Green/Chicory Coffee
I love the Charlie wallet, it’s so sleek, fits everything you need, looks good, and made out of the best material. The amount of pockets plus the center fold makes this a really hard product to beat
