KOCASO 43-inch Universal Aluminum Roof Rack Cross Bars — Anti-Theft Locks, 165 lb Capacity, Low-Profile

This low-profile set of cross bars fits vehicles with rain-groove spacing between 109–114 cm (42.91–44.88 in) and is built from high-strength aluminum alloy for long-term durability. Each bar supports up to 165 lbs, includes anti-theft hardware and weather-resistant covers, and ships with the mounting brackets, rubber pads and stainless steel braces needed for installation. The curved end design reduces wind resistance and noise, while the ABS lock covers protect keyholes from the elements.

How strong and stable are these cross bars for heavy loads?

The KOCASO bars are engineered from reinforced aluminum alloy to deliver a reliable load-bearing platform without a lot of extra weight. Each bar is rated for 165 lbs, making them suitable for most roof cargo scenarios when mounted correctly to compatible rain-groove vehicles.

• 165 lbs (75 kg) capacity per bar under proper installation
• High-strength aluminum alloy construction for corrosion resistance
• Stainless-steel braces and premium base brackets add mounting rigidity

Will these cross bars fit my car and how do I install them?

The system fits cars where the distance between the roof rain grooves measures 109–114 cm (42.91–44.88 in). KOCASO includes a full mounting kit and a straightforward manual so DIY installation is possible on compatible vehicles.

• Measure rain-groove center-to-center before ordering (109–114 cm required)
• Includes base brackets, hooks, rubber pads and stainless braces for secure mounting
• Installation instructions provided; 24-hour customer support available for fit or setup questions

How does the anti-theft feature work and how weatherproof is it?

Each cross bar is supplied with keyed anti-theft locks and durable ABS covers to protect the keyhole from rain and grime. The lock inserts secure the bars to the mounting hardware so the rack stays locked in place until you remove the stainless steel brace with the supplied key.

• Anti-theft keyed locks included for each cross bar
• ABS protective covers shield keyholes from weather and dirt
• Stainless-steel locking brace provides tamper resistance

Will these bars affect wind noise and vehicle appearance?

KOCASO designed the bars with curved end caps to reduce wind resistance and lower in-cabin noise compared with simple square bars. If you notice residual whistle or vibration on your vehicle, small rubber bands or the provided rubber pads can be adjusted to minimize noise without altering looks.

• Curved ends reduce wind drag and lower wind noise
• Low-profile, vehicle-friendly aesthetic preserves roofline appearance
• Rubber pads included to tune fit and dampen vibration or rattle
