A ground-engaging track includes a track chain formed of standard links and at least one master link. The master link include a first half link and a second half link, clamped together by way of a forward bolt and a rearward bolt. Clamping surfaces of the first half link and the second half link form a first tooth set and a second tooth set, respectively, which may include a total of 2 or 3 full teeth and tooth roots, confined in distribution between a forward bolt hole and a rearward bolt hole.

A track link rail surface and roller interface includes a first roller including a cylindrical configuration defining a radial direction, a longitudinal axis, a circumferential direction, and a plane containing the radial direction and the longitudinal axis. The first roller includes a first track link rail engaging surface including a first concave arcuate surface defining a first concave radius of curvature. The interface includes a first track link including a first track link rail surface including a first convex arcuate surface defining a first convex radius of curvature that is less or equal to the first concave radius of curvature.
