General Motors recently conducted a test showing the 2015 Chevrolet Silverado 2500 HD’s frame is stronger than the current (though outgoing) Ford F-250 Super Duty. This is important since work trucks take a lot of abuse on job sites and contractors want the strongest and most durable truck they can buy.
The frame-twisting test conducted by AMCI Testing, a third-party research firm, placed both trucks on staggered ramps. This position places a large amount of torque on the frame and is similar to parking a truck on an uneven surface. AMCI then measured the distance of displacement of the cab and body. This distance shows the amount of twist the frame was subjected too. In essence, the less displacement means the frame can handle the torque better.
Photos released of the test show clearly the Silverado HD was superior in this test with just .26 inches of twist compared to the Ford F-250’s .94 inches of twist. General Motors says the frame twist on the Ford was so great, the tailgate couldn’t be lowed on the F-250. On the other hand, the Silverado’s EZ-Lift and Lower Tailgate operated without problems.
“The use of high-strength steel in the Silverado HD is what allows the Silverado to handle even the toughest of jobs,” said Jeff Luke, General Motors’ executive chief engineer for full-size trucks. “Paired with a fully boxed frame, high-strength steel is what makes the Silverado come from the family of the most dependable, longest-lasting full-size pickups on the road.”
Along with the high-strength steel in the frame, GM also points to the use of roll-formed steel vs. the stamped steel bed of its competitors as a key reason why its truck performed better.
