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.

Little pieces break off
Color: Dogwood (Brown), Size: Large (Pack of 1)
My dog is obsessed with this. It does last a long time even given her strong chewing capabilities. I wish it was a little bigger. The main reason I rated it so low is when my dog is chewing on this it breaks off a little plastic peice and sometimes it hits the back of her throat making her cough so you have to supervise with this.

Great for aggressive chewers
Color: Dogwood (Brown), Size: Large (Pack of 1)
My dog is an aggressive chewer so they are great for her. I would love to have one a bit thinner so it could fit in a holder so it is easier for her to hold while eating. This keeps her busy and is long lasting. I have purchased these multiple times.

Durable and a favorite toy
My 7 month old Black Lab loves this bone. She is a chewer and has gone to town on the three ends. They are roughed up a bit but holding up better than expected. Highly recommend for dogs that love to chew.

Perfect for aggressive chewers
I have a 2 year old pittie and she chows thru bones in minutes, even those reviewed as "long lasting". This thing is still going strong after 9 months. She was not initially interested, had to spread peanut butter on one end, one time, and now it is her go-to chew toy. Looks a little mangled after all this time but she's not even 75% thru it. Highly recommend, no stomach issues.
