3.5-Inch Component Box with Upper Control Arms, GM HD (A Variant)

3.5-Inch Component Box with Upper Control Arms, GM HD (A Variant), fitment-checked

The A-suffix variant, and the suffix is the whole point: this box is supplied against parent kit C14350A specifically. Vehicle coverage and lift height match the unsuffixed box, so the kit number on your paperwork is what tells the two apart.

Skyjacker builds more than one 3.5 in. component box for the 2014-2016 GM heavy duty trucks, and they differ by which parent kit they belong to rather than by anything visible in the fitment table. This is the A variant, supplied for kit C14350A, carrying 3.5 in. of hardware with upper control arms. Coverage is the Silverado 2500 HD and 3500 HD and the Sierra 3500 HD. Boxed weight is 48.9 lb. Ordering by vehicle alone will not distinguish it. Order by the kit part number.
