General Motors SUV roof rack crossbar modification kit with 75kg load capacity and adjustable length

This roof rack modification kit provides a functional solution for expanding the cargo capacity of compatible General Motors SUVs. The alloy crossbars offer substantial 75kg load support while maintaining adjustability between 120cm and 135cm to accommodate various vehicle models. Designed specifically for installation on vehicles with prefabricated split longitudinal pole systems, this kit includes two complete roof luggage rack crossbars with all necessary mounting components. The straightforward design focuses on practical utility rather than specialised features, making it suitable for general cargo transport needs without complex installation requirements.
Features and Construction

The roof rack crossbars are built with alloy material construction, providing structural integrity for the stated load capacity. The adjustment mechanism allows length modification between 120cm and 135cm to ensure proper fitment across supported General Motors SUV models.
Material and Build
The alloy construction offers inherent strength characteristics appropriate for roof rack applications without requiring additional performance claims. The material choice supports the 75kg load capacity while maintaining a balance between durability and weight considerations for vehicle mounting. Crossbar design focuses on functional load distribution across the supported span, with construction details oriented toward secure attachment to prefabricated vehicle mounting points.
Size and Practical Fit
With adjustable length ranging from 120cm to 135cm, these crossbars can accommodate various General Motors SUV models within the supported vehicle category. The adjustable nature allows users to customise the fit for optimal placement on their specific vehicle, ensuring proper contact with mounting points and adequate clearance from roof features. This adjustability represents the primary fitting mechanism, eliminating the need for multiple fixed-size options while maintaining compatibility with the targeted vehicle mounting system.
Uses and Placement

The roof rack crossbars serve as a platform for securing luggage, equipment, or recreational gear on General Motors SUVs. The 75kg load capacity supports substantial cargo while the design maintains compatibility with standard roof rack accessories and mounting systems.
Event or Professional Use
For events, trades, or professional applications requiring additional transport capacity, these crossbars provide a practical solution for GM SUV owners. The 75kg capacity accommodates equipment cases, tool containers, or event materials that exceed interior space limitations. The straightforward installation on prefabricated mounting systems makes them suitable for users who need reliable cargo expansion without permanent vehicle modifications or complex fitting procedures.
Everyday Home Use
For domestic applications, the crossbars support luggage for family trips, sports equipment transport, or bulk shopping items. The adjustable length ensures proper fitment on various GM SUV models commonly used for family transportation, while the alloy construction provides sufficient durability for regular use scenarios. The design accommodates standard roof boxes, bike carriers, or cargo baskets that many households already own or might consider adding for expanded utility.
