Our Hydropower hydraulic brake assist power booster fits 1973-87 Chevy and GMC trucks and generates up to 1800psi of line pressure to the brake calipers. It is fitted with a POL or Wilwood master cylinder and a Black Out adjustable proportioning valve. This kit is powered by hydraulic line pressure from the power steering pump. Firewall and valve cover clearance is equivalent to a 7" diameter vacuum booster. The firewall brackets are correct for 73-87 GM truck applications.
The average power steering pump puts out from 800psi to 1400psi line pressure. The Hydropower unit uses this to convert to pressure to apply against the master cylinder. This greatly improves stopping performance and driver feedback. These hydraulic power boosters can be easily installed on an existing vacuum booster vehicle or used to convert a manual brake setup to power with ordinary hand tools and average mechanical ability.

Keeps her busy!
Color: Medium size (5.9")
Our Molly loves this. Only thing is that it is a little too big for our Maltipoo, but she still tries to keep up with it.

Tough
Color: Medium size (5.9")
So far my dog hasn’t destroyed it! And it’s been a month. So I call that a win. Plus he loves it.

Perfect for active dogs
This is a must-have if your dog loves to fetch. It throws the ball far with very little effort and keeps your hands clean—no more slobbery chuckit balls. Lightweight, durable, and makes playtime much more fun (and less tiring for me!).

Way better than the M size for us
Like most people that have dogs I first went with the M size or Tennis ball size (about 2.5") chuckit for my 65-70 lbs Lab. After having that for a while and my dogs' evolution from liking to chase the ball to wanting to catch it, I started seeing how the M size could cause some life threating problems for my pup. I was on the fence for several weeks when I came across this option that included a 3" ultra ball as well as a 3" fuzzy tennis ball like ball. These balls can fly so much farther with less effort and my furry friend seeming to like them more than the 2.5 inch. It also seems to fit their mouth better allowing them to enjoy 'the game' (you lost by the way) much more. If you have a larger dog or your dog has a big mouth, please trust me when I say skip the 2.5" M size balls. You and your dog will haves much more fun with this 3" size
