In-Depth 2021 Chevrolet Blazer Towing Review
The 2021 Chevrolet Blazer combines athletic styling with versatile mid-size SUV utility, offering a conventional 2021 Chevrolet Blazer towing capacity ranging from 1,500 lbs on baseline models up to 4,500 lbs on V6 models equipped with trailering hardware. Powertrain options begin with a 2.5-liter naturally aspirated 4-cylinder outputting 193 horsepower at 6,300 RPM and 188 lb-ft of torque at 4,400 RPM, step up to a 2.0-liter turbocharged 4-cylinder delivering 227 horsepower at 5,000 RPM and 258 lb-ft of torque at 1,500 RPM, and peak with a potent 3.6-liter V6 generating 308 horsepower at 6,600 RPM and 270 lb-ft of torque at 5,000 RPM. All engines route power through a 9-speed automatic transmission. The unibody chassis spans an unladen curb weight of 3,810 lbs to 4,282 lbs, a Gross Vehicle Weight Rating (GVWR) of 5,000 lbs to 5,600 lbs, and a Gross Combination Weight Rating (GCWR) reaching 8,250 lbs to 9,250 lbs on tow-rated trims.
To achieve the maximum 4,500 lb trailering threshold, configuring the 3.6-liter V6 with factory tow package specifications is required, adding a heavy-duty cooling system, hitch guidance software, and a 2-inch receiver hitch with a 7-pin wiring connector. The maximum certified tongue weight scales from 150 lbs on 2.5L models up to 450 lbs on 3.6L V6 models, requiring careful load distribution to stay within vehicle limits. While the Blazer max payload rating varies based on interior trim and equipment, the 5-link independent rear suspension maintains level tracking and cornering stability under heavy tongue loads. Drivers also benefit from advanced powertrain and torque specs, drive mode selector software, and available twin-clutch all-wheel drive, making the 2021 Blazer a confident performer for hauling campers, boats, or recreational gear.
