Restore the right relationship
Tire size and vehicle use can change how gearing feels.
A gear change may be considered when larger tires, towing demands, or a changed vehicle setup affects drivability and usable performance.
BD Fabrication helps customers discuss gear-ratio direction using the vehicle, axle configuration, current tire size, planned tire size, driving conditions, towing needs, and overall build goals.
Common decision factors
Tire size, axles, use, and drivability.
Current and planned tire size
The size change is an important part of understanding how the complete setup may behave.
Vehicle and axle configuration
Year, make, model, drivetrain, axle details, and existing modifications help define the project.
Towing and load demands
Share trailer, load, and work use so the shop understands what the vehicle is expected to do.
Driving priorities
Daily driving, highway use, off-road use, and low-speed control all influence the conversation.
The process
From vehicle details to a confirmed gear package.
Document the current setup
Share the vehicle, axle information if known, tire size, current modifications, and any drivability concerns.
Define the finished setup
Discuss planned tire size, lift, towing use, highway driving, off-road use, and the result you want.
Review gear direction
The shop evaluates the available information and helps narrow the appropriate parts and scope.
Schedule the package
Confirm parts availability, related work, appointment details, and the agreed installation plan.

What shapes a gear change estimate?
Scheduling & preparation
Share what changed and how the vehicle feels.
Provide the vehicle details, current and desired tire size, axle information if known, towing needs, driving priorities, and any performance or drivability concerns.
For the clearest plan, include any future lift, wheel, tire, or towing changes that may affect the finished setup.
Gear Change Packages FAQ
Gear change questions worth discussing first.
When might a gear change be considered?
A gear change may be discussed after a significant tire-size change, when towing needs change, or when the finished vehicle no longer drives the way the owner wants. The decision is vehicle-specific.
Can BD Fabrication recommend a gear ratio?
The shop can review the vehicle, axle configuration, tire size, intended use, towing needs, and planned upgrades to help narrow the appropriate direction.
Should gearing be planned with a lift and tires?
Yes. If lift, wheel, and tire changes are planned, discussing the finished setup together gives the shop better information for gear planning.
What vehicle information should I provide?
Provide the year, make, model, drivetrain, current and desired tire size, axle information if known, current modifications, towing use, and driving goals.
