Revised   Rear  Upright  Top  Block  &  Steer  Arm   for   VanDiemen
This Revised rear upright Top Block & Steering Arm includes several beneficial features:
It eliminates the spacer plate between the upright and the block.
It incorporates an extra 20mm dowel that indexes in the center of the stock VD upright.
This provides extra shear strength as the stock small dowels are located close to the edge of the upright casting.
They will often 'egg-out' the pockets or break through the casting wall especially if you use the curbs driving.
The Block has a window that allows for servicing the brake disc drive pins.
This allows you to change brake discs or drive pins without removing the block from the upright.
The Block is also designed with a much larger camber shim surface area for increased clamp load.
We supply wider surface area camber shims for this part.
The Revised rear steering arm has a matching camber shim configuration for a more ridged assembly.
The Rear Steering Arm also has a window that allows easier access to the camber bolts.
