A method of building and operating a land-based drilling rig with a high-capacity mast include providing a platform collapsed on a substructure over a proposed well drilling location and building the high-capacity mast in a horizontal condition by attaching a lower portion of the high-capacity mast to the platform. The high-capacity mast having an opening formed therein sized to accommodate four Range 2 pipes or three Range 3 pipes. The high-capacity mast may be raised from the horizontal condition to a vertical condition by pushing the side of the high-capacity mast to pivot the high-capacity mast about a pivot point on the platform. The platform may be raised from a collapsed condition to a raised condition over the substructure. Some implementations include dual racking boards on the high-capacity mast.

Shock absorber systems include a drive plate having a plurality of removable lugs. The drive plate is connectable to a rotary drive shaft. The shock absorber further includes a driven plate connectable to a rotary driven shaft. A housing may be fixedly secured to either or both of the drive plate and the driven plate. The housing may have an outer wall forming a hollow center portion and a plurality of openings extending through the outer wall to the hollow center portion. Each opening of the plurality of openings may have first and second positive stops formed thereon. The shock absorber further comprises an elastomeric member disposed in the housing between the drive plate and the driven plate. The elastomeric member is configured to absorb vibration from the driven plate. Each removable lug of the plurality of removable lugs has first and second striking faces at a radially distal edge and on circumferentially opposing sides.
