Hydro Assist Ram

Back to article View Gallery
4 of 5
A hydro-assist ram is typically attached at one end to the front solid axle. Its opposite end often attaches to a point on the drag link or similar. This relieves some stress loading from the frame-mounted steering box. However, a driver must be prudent not to use the extra power indiscriminately and overstress the axle components. Full hydro systems are commonly used on rock buggies and race vehicles. They eliminate all mechanical linkage, which is advantageous for high articulation and long-travel applications where mechanical linkage movement and clearance issues could be troublesome. Full hydraulic systems are typically not street legal, and do not have the same return-to-center characteristic.
