Key benefits Protects the shift mechanism from dirt, moisture, and spills to reduce wear and corrosion on internal components. Cushions hand pressure and road vibrations for smoother, quieter gear changes. Durable, weatherresistant construction stays flexible in heat and resists cracking in cold for longterm use. Features and specifications Replacement part number: 68400287AA. Exact replacement fit for listed models; no vehicle modifications required — simply remove the old cover and install this one. Material: weatherresistant, temperaturetolerant polymer designed to resist scratches, cracking, and general damage. Function: snugly covers the junction between the shift lever and vehicle body to block contaminants while absorbing shock and vibration during shifting. Compatibility and installation Compatible vehicles: 2009–2010 Dodge Ram 1500, 2011–2018 Ram 1500, and 2021 Ram 2500. Installation: direct replacement of the existing shift knob cover/boot; standard hand tools may be used but no cutting or vehicle alteration is . Performance Remains flexible under summer heat and resists cracking in winter cold, maintaining a reliable seal against dust and water. Helps reduce metalonmetal contact and noise by cushioning the shift lever and dampening roadinduced vibration. Surface resists everyday scratches and holds up to routine use for sustained protection of the shift system and transmission controller. Practical use scenarios Daily commute: prevents road dust and small debris from entering the shift linkage while reducing vibration and noise over potholes and rough pavement. Outdoor work or offroad use: keeps mud, water, and grime out of the shift mechanism to limit accelerated wear and rust when driving in muddy or wet conditions. Every‑day spills: blocks spilled beverages and light rain from reaching internal components, helping avoid sticky or corroded linkages after accidental spills. What to expect A directfit replacement that preserves factory fit and function. Improved longevity of the shift area through environmental protection and vibration dampening. Simple swapin installation with no vehicle modifications required.
