Our Hydropower hydraulic brake assist power boost fits 1947-55 Chevy and GMC trucks and generates up to 1800psi of line pressure to the brake calipers. It is fitted with a POL master cylinder and proportioning valve. This kit is powered by hydraulic line pressure from the power steering pump. Frame clearance is equivalent to a 7" diameter vacuum booster. The frame brackets are correct for 47-55 GM truck floor mount 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.

Good product.
This works well. It's sturdy and holds the phone well. It does keep the vent from adjusting but not a big deal.

Loving it so far
I’ve only had this about a week but I like it so far. It has a hook that grabs the vent blade and is very sturdy. It also has a part that slides up and down. I realized after a few days that can be tightened as well. Makes the phone even more still. There is a small button on the right that releases the arms that grab the phone. I didn’t see that noted on the instructions so mentioning it here so no one pulls on them like I did a few times. As long as this doesn’t damage my vent, I will be pleased.
