This kit is a fabricated installation. It is meant to provide the original geometry and more robust installation than other kits on the market. By direct attachment to the frame, this kit provides a stronger mounting surface and increases the strength of the frame-rail. This weld on kit, allows the idler/pitman to stay more parellel with each other than other kits on the market due to the closeness to the framerail and better angle of installation to the centerlink. This kit is very easy to inspect with no hidden bolts or hardware that is hard to see.
This steering kit addresses all concerns by attaching the M83 box in the correct location just like the box was installed on later model H1s. This allows the correct geometry to be achieved. On top of that it adds additional plate on each side of the frame and increases the size and thickness of the frame bosses. This kit is stronger than the original design!
It is an extremely important modification to the Hummer H1 and HMMWV platfroms. Read below and watch the commercial for more information.
