HOLLAND REPLACEABLE KINGPINS PROVIDE:

Secure installation.

Ease and economy of replacement should wear or
damage occur to the kingpin.

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. 

STANDARD FEATURES INCLUDE:

1.

Secure installation with eight .75˝ diameter Grade 8
bolts and safety wire lock.

2.

Kingpins are made of AISI 8630H alloy steel and
hardened to 302-363 BHN. When properly installed,
will meet or exceed the performance requirements set
by the Society of Automotive Engineers (SAE) and the
Truck Trailer Manufacturers Association (TTMA).

3.

High impact and wear resistance.

4.

Housings are made of AISI 4130H alloy steel for
weldability.

5.

100% Brinell hardness tested.

6.

100% magnetic particle tested (to inspect for integrity
below the surface).

7.

Ultrasonic tested (MS 105, Tightened, C=0).

8.

Bolster plate thicknesses are designed into the
housings as shown. Only one kingpin, either SAE 2˝ 
or 3.5˝ is required for service parts.
