Black MAX Shock for GM 2500 HD & 3500 HD (2011-2023)

Black MAX Shock, fitment-checked

Thirteen model years of GM heavy duty on one Black MAX, 2011-2023, at 0-3.5 in. of lift. Skyjacker builds a monotube to the same dimensions for these trucks, so the series is the choice here.

The band covers a stock truck through to a moderately lifted one: 0-3.5 in. , which makes this a broadly useful fitment. Dimensions are 20.14 in. extended and 13.53 in. collapsed, with the Black MAX black boot. Coverage is the Silverado 2500 HD and 3500 HD and the GMC Sierra equivalents from 2011 through 2023. At 8.5 lb boxed it is a substantial damper, as a three-quarter-ton unit should be. A monotube exists at identical dimensions in the same range if you want that construction instead.
