The genuine Western 63979 Shock Absorber Kit serves as a critical impact-mitigation component engineered explicitly to manage the intense dynamic forces experienced by your snowplow during commercial clearing operations. This factory-original shock absorber attaches directly between the plow’s A-frame and the pivoting moldboard structure to dampen the violent recoil action generated immediately after the blade trips upon striking hidden obstacles like raised manhole covers or concrete curbs. Consequently, professional fleet mechanics install this authentic kit to minimize mechanical fatigue on structural components, including the trip springs, quadrant, and vehicle-side mount frame.
This heavy-duty stabilizer features precision-machined 3/4-inch pin holes on both ends to guarantee a uniform, vibration-resistant fit directly into standard factory bracket layouts. Because severe winter road conditions introduce high-frequency vibrational stress and freezing moisture, Western coats the outer casing with a premium corrosion-resistant finish to protect the internal fluid chambers and piston assemblies. Choosing an authentic manufacturer-grade replacement ensures proper damping resistance thresholds, preventing the harsh chassis jolts and dangerous vehicle feedback common with low-grade aftermarket alternatives.
For commercial fleet managers and professional operators, executing a proactive swap on scored, leaking, or dead shock absorbers during seasonal shop maintenance prevents catastrophic base angle cracks and reduces truck downtime. This comprehensive kit arrives ready for installation, providing the exact factory-specified length and valving configuration required to maintain an efficient, controlled plowing experience across wide thoroughfares and packed parking lots.
Benefits of the Western 63979 Shock Absorber Kit
-
Genuine OEM Engineering: Designed specifically for an exact drop-in installation across Western UltraMount plows, including Pro Plus, Pro-Plow Series 2, Midweight, and Prodigy series straight blades.
-
Controls Blade Trip Recoil: Smoothly dampens the return motion of the moldboard after tripping to prevent violent metal-on-metal slamming.
-
Heavy-Duty 3/4″ Pin Mounts: Solid machined eyelets on both ends match factory mounting bolts perfectly to eliminate slack and structural play.
-
Protects Vehicle and Plow Framework: Lowers structural stress transferred directly to the truck frame, A-frame assemblies, and quadrant pins.
-
All-Weather Structural Shell: Premium steel housing and high-tolerance internal fluid seals resist sub-zero thermal extremes and caustic road salt penetration.
