Abstract: A contraction joint includes a mandrel at least partially disposed within an upper tubular member, the upper tubular member being capable of moving uphole and downhole to change a length of the contraction joint. The contraction joint also includes a nipple housing connected to the upper tubular member, a piston housing connected to the nipple housing, a support piston disposed in the piston housing, the support piston being affixed to an upper mandrel sub of the mandrel via at least one piston retaining device, a lock housing disposed between the upper tubular member and the upper mandrel sub, and a stroke locking mechanism disposed within the lock housing, the stroke locking mechanism including a profile that engages the nipple housing.
