Due to the unbalanced displacement of an assist cylinder, which will create a constantly fluctuating fluid level in a reservoir, a large capacity remote reservoir is required with Big Bore XD Cylinder Assist setups in order to provide enough room for fluid level changes and expansion due to operating temperatures. 

The hose that supplies fluid to the pump from the reservoir should not exceed 16 inches to avoid collapse under suction or the creation of a vacuum situation that will result in fluid aeration inside the pump. Excessive fluid aeration is the most common cause of a noisy and/or whining pump that could possibly lead to catastrophic failure.


A common component failure on the Jeep JK is the original high-pressure hose assembly. It is manufactured with a plastic liner that can delaminate from the interior of the hose, especially after constant excessive heat cycles. A common result is the obstruction of the high-pressure "IN" port of the steering gearbox, choking off the fluid flow and causing the fluid to overheat. This could lead to a complete power steering system failure. To remedy this issue and to improve overall system efficiency, we strongly recommend installing our HK2095 High-Pressure Hose Conversion Kit on all 2012-18 Jeep JK.
