What is the wheelbase of a 1958 GMC truck?
There isn’t a single wheelbase for all 1958 GMC trucks. Wheelbase varied by model and configuration, with common lengths spanning roughly from about 115 inches for light-duty pickups to the 125–133 inch range for heavier-duty variants. For an exact figure, you must identify the specific model code, cab/bed configuration, and check the vehicle’s data plate or factory documentation.
Historical context and what the wheelbase means for 1958 GMC trucks
During 1958, GMC’s truck lineup covered a range of duties from light pickups to heavier-duty chassis. The wheelbase is the distance between the centers of the front and rear axles and directly influences ride, payload, and overall vehicle size. Because GMC offered multiple body styles within the same year, the wheelbase varied to accommodate different bed lengths, cabs, and axle sets.
Model families and typical wheelbase ranges
The following ranges reflect common configurations in the 1958 GMC truck lineup. Exact numbers depend on the specific model, cab/bed setup, and any factory options.
- Light-duty pickups (shorter wheelbase): approximately 115 inches
- Medium- to heavier-duty models (longer frames): approximately 125 inches
- Longer or specialized configurations (one-ton and above): approximately 131–133 inches
Note: These figures are general guidelines. For a precise wheelbase, identify the exact model code and cab/bed configuration, and/or measure or consult the original data plate or factory specifications.
How to verify the wheelbase on your 1958 GMC truck
To confirm the wheelbase for a specific 1958 GMC truck, use a direct measurement or consult official documentation. The following steps outline a straightforward approach.
- Locate the data plate or VIN plate on the vehicle, typically found on the driver’s door or near the dash; the plate may list chassis or wheelbase-related details.
- If measuring, measure the distance from the center of the front axle to the center of the rear axle along the vehicle’s centerline. Use a straightedge or laser measure for accuracy.
- Record the measurement in inches and compare it to common 1958 GMC wheelbase ranges to narrow down the exact configuration.
- Cross-check with the model code, trim package, and cab/bed configuration in the original GMC documentation, shop manuals, or vintage dealer catalogs for confirmation.
With the measurement and model details, you can identify the exact wheelbase for your specific 1958 GMC truck and confirm whether it aligns with common period configurations.
Summary
The wheelbase for 1958 GMC trucks is not a single value; it depended on the model and configuration. Typical ranges run from about 115 inches for light-duty pickups up to roughly 125–133 inches for heavier-duty variants. For accuracy, identify the exact model code and cab/bed setup, check the data plate, or consult factory documentation. This approach ensures you know the precise wheelbase of any given 1958 GMC truck.
