The 2 Stainless Braid 2 Rubber Hose Kit will have have a PTFE (generic term for Teflon) inner hose wrapped in a stainless braid weave on the high pressure side, while the 4 Rubber option has a stainless braid weave in the middle, rubber inside and out and is wrapped in a black cloth weave. The first two options use a low pressure rubber hose and hose clamps on the low pressure side, which is all you need, but do the high pressure side differently. You can choose from the 2 Stainless Braid 2 Rubber Hose Set, 4 Rubber Hose Set, or the 4 Stainless Braid Hose Set. The Hydro-Boost taps into the 1,000 pounds or more of pressure in the power steering system, so you will need high pressure hoses and fittings from the pump to the booster, and from the booster to the steering unit. Units have to be disassembled for powder coat, and there is a lot of work that goes into preparing units for chrome, so there will be a longer lead time on chrome, powder coat, or other custom work. We offer powder coat options, which will smooth out the bumps of the casting and look great. The Hydro-Boost comes standard with a durable black paint that will look good and last. If you have an existing Hydro-Boost that you would like serviced, that came stock on your vehicle, or that you bought from us years ago, call or email for pricing and instructions. Select 'New' if you are replacing your existing Hydro-Boost with a new one, or converting to a Hydro-Boost from something else. The aluminum canister on the side is the accumulator, which stores pressure in case your engine dies to provide you with some braking and steering assist to help you come to a safe stop.Ĭondition: The Hydro-Boost is very simple in design, and requires little service, typically a fresh set of seals every 100-200 thousand miles. The Hydro-Boost is smaller in diameter than vacuum boosters, being about the dimensions of an iron master cylinder, it mates to the firewall/brake pedal and the master cylinder the same way a vacuum booster does, and it fits anywhere a vacuum booster will, as well as many place a vacuum booster won't. Either way, you want the Hydro-Boost, and it is the first place to start.

There is usually more potential in the stock front and rear brakes that you already have on the vehicle, so the Hydro-Boost is the logical way to go for consistent braking power if you wanted to put bigger front and rear brakes on, or to make your stock brakes produce. The power steering pump is belt driven, rather than electric motor driven like a vacuum pump, so it is more reliable, and the Hydro-Boost piggybacks off of this by being added into the high pressure line on its way from the pump to the steering unit. You can spend a lot of money on calipers that are advertised as 'big', but if they are bigger than your stock brakes, they will be more demanding for pressure and volume, so they won't make an improvement unless you have a more powerful brake booster and master cylinder combination to increase the line pressure and volume that they will receive. Going down in size on the master cylinder bore can cheat to spike up the pressure to the caliper pistons, but it reduces the volume of fluid the caliper piston bores get, giving you an incredibly long pedal throw. The feedback from customers is that vacuum pumps are loud, don't keep up in traffic, burn out too quickly, stock replacements are hard to find after 10-20 years, and aftermarket ones are of low build quality. The Hydro-Boost should provide an impressive increase in power with your stock pump, but power steering pumps can be modified as well to produce more pressure, which gives you room to get even more braking and steering assist, when using the Hydro-Boost, if you are left wanting more. The Hydro-Boost is more powerful overall, and does not depend on manifold vacuum, so it is great for vehicles that have a high performance engine, diesel engine, tall tires, tow a trailer, or are just heavy. Big camshafts and other engine modifications rob vacuum, and diesels don't make vacuum at all. Most 5 lug and larger vehicles produce more than a 1,000 pounds of pressure in the power steering system, the Hydro-Boost taps into this rather than the 15 pounds of vacuum that you hope to get from your engine manifold.
