The HWH R3847 Hydraulic RV Jack Replacement Spring Kit contains two springs, each measuring 1-11/16-inch X 13-3/8 inches (from end of hook to end of hook) or 11-1/8 inches (from base of hook to base of hook). It is used on all HWH Hydraulic Motorhome 6,000 lb. and 9,000 lb. capacity jacks with 13-inch or 15-inch stroke.
If a vehicle is parked or stored for an extended period of time and the jacks fail to retract completely, extend the jacks back down to the ground then retract the jacks again. If the jacks do not retract completely without assistance, replace the springs. There are two (2) springs included in each spring kit. The correct spring kit must be used.
