An adjustable bail extension includes a tubular outer link, an inner link disposed and axially movable within the bore of the outer link, and an adjustment mechanism for releasably clamping the outer link to the inner link at any of multiple locking positions defined by sets of locking grooves formed at axial intervals on the inner link. The adjustment mechanism is operable between a locked position wherein a collet assembly linked to the outer link engages a selected locking groove set and thereby enables axial load transfer between the inner and outer links; and an unlocked position wherein the collet assembly does not operatively engage any inner link grooves, such that the inner link is axially movable within the outer link to enable adjustment of the overall length of the adjustable bail extension by repositioning the collet assembly to engage the inner link grooves at a different locking position.
