Overview
Engineered for strength and configurability, the Martin Off-Road Roof Rack for the GX 470 delivers serious off-road utility with a refined, vehicle-specific fit. Its modular design and precision-formed side rails support a wide range of overland setups, while bolt-on installation ensures quick integration with no vehicle modification. Built from thicker material than most racks on the market, it’s a system meant to perform in rugged conditions.
Construction
Fabricated from 1/4-inch CNC laser cut and bent 5052 aluminum, the side rails and supporting structure offer a high load-bearing capacity without excessive weight. The entire rack is coated in a satin textured black powder finish for added abrasion resistance and long-term corrosion protection. All mounting hardware is stainless steel to withstand harsh environments.
Design
With a modular crossbar system and precision-fit side rails, the rack supports rooftop tents, lighting systems, recovery gear, and storage platforms. The design allows for extensive customization, with multiple mounting slots and access points along the full length of the rack. T-slot compatible crossbars provide a flexible base for universal and proprietary accessory mounts.
Installation
The rack installs using the factory roof mounting locations with no drilling required. The included stainless steel hardware ensures a tight, secure fit that resists vibration and movement under dynamic load conditions.
Capacity
Users should ensure even load distribution and follow vehicle roof weight ratings. Weight capacity varies depending on rack configuration and installed equipment. Always use proper tie-down procedures and avoid overloading.
