Description

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 parallel with each other than other kits on the market due to the closeness to the frame rail 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 an 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 for the Hummer H1 and HMMWV platforms.  Read below and watch the commercial for more information.

·         1/4″ Frame Formed Inner Frame Plate with Boss Holes

·         1/4″ Frame Formed Outer Frame Plate with Boss Holes

    Best on the market, period!
    I was so excited when the kit came out and purchased it right away. I originally purchased “a bolt on mount” but never installed it because I became concerned with the way it attaches to the frame. Although it seemed stout, utilizing hardware that I could not inspect on a routine basis that was attached to the device that keeps my vehicle on the road was a major concern. I was also concerned how it moved the M83 steering gear closer to the idler than the original design and causes the pitman arm and idler arm to not swing in parallel.
    I always wanted the M83 box because it was superior to the saginaw box that was originally installed. With the M83 box being so large and powerful I wanted to make sure it could do what I wanted both on road and offroad without being concerned that it would stay attached to the truck. I was also concerned about getting the correct geometry because the wrong geometry will wear out the steering components fast.
    This steering kit addressed all my concerns. It attaches 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! Thanks for making such a great product and addressing the shortcomings of others products.
