There are two types of Hydroboost we supply, a Hydroboost and a Hydroboost II.

Hydroboost - This unit puts out 2,500-2,700 lbs of pressure. It has a nitrogen chamber that allows for emergency stopping after the vehicle stalls. It can be used on any vehicle, however we recommend only using this booster and not the Hydroboost II if you have D44 axles or bigger or 36-53 inch tires as you need the extra power. This unit is 4.5 inches in diameter, with the 2-inch accumulator sticking out towards the engine at the 7 o’clock position.

Hydroboost II - This unit puts out 1,800-2,200 lbs of pressure. It has an internal accumulator, but the accumulator doesn’t work nearly as well as a standard Hydroboost after the vehicle stalls. We recommend this unit for stock axles and tires 35 inches or smaller. If you feel better with a Hydroboost that stops the vehicle after it stalls use the regular Hydroboost. This unit is 4.5 inches in diameter.

Power Steering Pumps - If you're using a Saginaw style pump (CJs) you don't need to upgrade your pump as long as your pump is in good working order. YJs, TJs ands most XJs need an upgraded pump. On the XJs 84-86 non diesels don't need to be changed, the diesel does, all XJs after 86 need a pump change.

Master Cylinder Line Kits - If you use our master cylinder for your TJ you'll need this kit to connect the master cylinder to the proportioning valve. It's offered for the YJ for the stainless steel braided look.

Master Cylinders - Your original master cylinders will not fit our Hydroboosts. If you choose to buy your own master cylinder please call so we can advise what models you can use.

Hi-Flow Process - This is a process you’ll need if you add Rock-Ram, Ram-assist steering or full hydraulic steering. Rams use more fluid then a typical Hydroboost allows. So we at Vanco hi-flow the units internally to greatly increase the flow so any vehicle with these types of steering work perfectly.
