The "LD" stands for light duty for the 2007 Chevy Silverado Classic. There was also an HD that had the rear axle/suspension of the 2500 series. An HD would have 8-lug wheels. Yours look like 6-lug wheels which would mean it is an LD but since they are aftermarket wheels I can't be 100 percent sure. The HD models also came with recovery (tow) hooks as standard equipment. The sales code for the HDs was 15743. The HD models also had rear brake rotors that were 13 inches in diameter and 1.14 inches thick. The fronts were 12.8 inches in diameter and 1.5 inches thick.

There are a lot of other ways to determine if you have an HD if none of the above work for you. Just let me know.

If it is an HD you can use # AA4059 or # 57-1915.
