Rubber Cushion, 4.75 in., GD RCF
SAF-Holland

Four and three-quarter inch rubber cushion is a vibration isolation element used in SAF-Holland suspensions and linkage assemblies. The outer dimensions deliver a compact yet robust isolation pad that dampens impact from road irregularities and trailer dynamics. The GD RCF designation indicates a groove design variant with a specific rubber compound selected for resilience, abrasion resistance, and fatigue life under repeated load in weathered environments. The cushion provides a resilient interface between structural members, absorbing energy during coupling, decoupling, and road roll. This reduces transmitted stresses to adjacent metalwork, lowers noise levels, and prolongs service life of mounting hardware. It is compatible with assemblies designated in category 42734, which covers rubber isolation components in the SAF-Holland portfolio. VMRS 077-003-004 identifies its function in the gearbox or suspension sub-system as a cushioning element. Typical applications include trailer landing gear linkages, axle hanger interfaces, and coupling bridle mounts where a controlled degree of deflection is desirable. The part ships with no cross references, so verify compatibility with the specific truck or trailer model and the cushion’s durometer and mounting dimensions prior to installation. Replacement is routine during suspension maintenance to restore ride quality.
