REESE TOWPOWER 74177 Premium 1.980-Inch Diameter Tapered Trailer Wheel Bearing Protector Buddy Kit with 2 Chrome Caps and 2 Vinyl Dust Covers Product Overview

This REESE TOWPOWER premium wheel bearing protector buddy kit is an uninstalled dual-side marine maintenance assembly engineered specifically to maximize wheel bearing lifespans by sealing out ambient road dirt, sub-surface mud, and moisture tracks. Designed to precisely tap into standard 1.980-inch hub bore diameters common across boat trailers, utility flatbeds, and camper towables, this heavy-duty steel companion set prevents sub-surface bearing failures caused by internal axle vacuum cooling during water submersions. Structured with built-in lubrication Zerk fittings under spring-loaded piston reservoirs, it continuous maintains internal grease chamber pressure thresholds to eliminate component fatigue scales smoothly.

• Absolute Contaminant Protection: High-pressure spring-loaded piston chamber repels sub-surface lake water and road salt brine ingress, checking internal rust pitting tracks.
• Durable Mirror Chrome-Plated Steel: Heavy-gauge steel tool bodies undergo premium electrolytic chrome-plating treatments to successfully counter oxidation rust lines in coastal maritime conditions.
• Integrated Structural Lubrication Zerks: Central lubricant grease fittings allow easy top-offs with grease guns, saving installation tear-down time during routine preventive hub service loops.
• Flexible Vinyl Protective End Covers: Outfitted with 2 snug black vinyl outerwear caps to safeguard grease reservoirs from drying ambient dust scaling or highway wind-shear debris.
