Cab To Frame Wood

Cab To Frame Wood

Within the Chassis & PU Bed system, cab-to-frame wood establishes the mounting interface between the cab structure and the chassis. This category supports 1932-1947 Pick Up applications where wood blocks are used at cab mounting points to maintain proper spacing between the cab floor structure and the frame rails.

Early pickup designs often relied on wood blocks at specific cab mounting locations rather than full rubber pad assemblies. These wood pieces support the cab structure while controlling the vertical spacing between the cab mounts and the frame. When the wood blocks are installed correctly, the cab sits square on the chassis and the mounting bolts clamp the structure evenly across the frame mounting points.

Over decades of service, the original cab mounting wood frequently deteriorates from moisture exposure, compression, and long-term load from the cab structure. Rot, splitting, or crushed mounting surfaces are common in trucks that still retain original mounting blocks. When these pieces fail, the cab can settle unevenly on the frame, which often shows up as changing door gaps or uneven cab height from side to side.

Restoring the correct cab mounting wood is a necessary step before final cab alignment and body mounting adjustments are performed.

The Cab To Frame Wood subsystem supports the cab structure within the Chassis & PU Bed system by maintaining the correct spacing between the cab mounting points and the frame rails.

A Cab To Frame Wood block sits between the cab mounting structure and the frame mounting location. When the cab mounting bolts are tightened, the wood block provides the solid spacer that establishes the correct vertical relationship between the cab floor structure and the chassis.

This spacing is important for maintaining proper cab alignment relative to surrounding components such as the doors, cowl structure, and pickup bed. If the wood block compresses or deteriorates, the cab mounting bolts can draw the cab structure downward toward the frame, altering body alignment.

Wear is most often seen as compression around the bolt hole, splitting along the grain of the wood block, or rot caused by long-term moisture exposure. Once the wood begins to collapse, cab height can change slightly at the mounting point and alignment issues may appear across the body structure.

Fitment will vary by model and year.
