Yakima SkyPeak Rooftop Cargo Box Expansion Kit – Heavy Duty

Maximize your Yakima SkyPeak rooftop cargo box’s storage potential with this Heavy-Duty Expansion Kit. Designed specifically for Yakima’s SkyPeak series (models 2018+), this kit adds 50% more capacity while maintaining a sleek profile that reduces wind noise by up to 40%—perfect for cross-country road trips or daily commutes needing extra gear storage without sacrificing vehicle aerodynamics.

Engineered with marine-grade aluminum and UV-resistant polymers, the expansion module withstands extreme temperatures (-40°F to 160°F) and harsh weather conditions without warping or degrading—ideal for surfers storing boards + camping gear or families needing secure cargo space during vacations.

Security upgrades include Yakima’s Tri-Fork™ locking system, which secures both original and expanded compartments with military-grade encryption keys—10x stronger than basic cable locks—to deter theft in urban parking areas or campgrounds.

The tool-free installation attaches seamlessly to existing SkyPeak mounting rails in minutes, eliminating drilling or permanent modifications to your vehicle roof rack system—a standout feature compared to competitors requiring full box replacements for added space.

Backed by Yakima’s 5-year warranty against manufacturing defects, this expansion kit ensures reliable performance whether you’re hauling work-from-home supplies across town or securing kayaks + bikes during a multi-state adventure trip—without compromising trunk access or vehicle fuel efficiency.”
