A surgical stapling device includes a jaw assembly including a first jaw supporting an anvil assembly and a second jaw supporting a cartridge assembly. A drive assembly is translatable through the jaw assembly to effect the clamping and stapling of tissue. The drive assembly includes a clamping member and an adjustment member. The clamping member includes a first clamping surface configured to engage the anvil assembly. The adjustment member includes a second clamping surface configured to engage the staple cartridge. The first clamping surface is spaced from the second clamping surface to define a clamping height. The adjustment member is moveable relative to the clamping member between a first position and a second position to change the clamping height.
