Kingpin Catalog for technical info.

Holland kingpins meet all AAR, SAE and TTMA standards that set the boundaries for kingpin design, manufacture and use.

The Holland advantage results from what we do within those boundaries to "raise the bar" on machinability, heat-treatability and cost efficiency to improve performance, strength, impact resistance, wear resistance, and ease of installation.

WELD-ON CRUCIFORM

Industry-standard cruciform design.

WELD-ON MUSHROOM

WELD-ON DOUBLE SPOOL

"L" SERIES

This series of kingpins is designed specifically for van and enclosed trailers, but can be used on other types of trailers as well. The kingpin design permits economical replacement of the kingpin since it is bolted in place — no expensive rework of the trailer upper coupler.
