What is the rear axle ratio of a 2014 Toyota Tundra?
The rear axle ratio on a 2014 Toyota Tundra is not a single figure; it varied by trim, drivetrain, and configuration. Typical gear ratios in the lineup include 3.73:1, 4.10:1, and 4.30:1, with the exact number determined by the specific truck.
This article breaks down the common ratios used in 2014 Tundra models, explains how to identify the exact ratio on a given vehicle, and provides guidance for buyers and owners who need this information for towing, maintenance, or resale diligence.
Common rear-axle ratios used in 2014 Tundra models
Below are the rear-axle ratios that appeared in 2014 Tundra specifications. The actual ratio for any individual truck depends on engine choice, transmission, 4x4 vs 4x2 configuration, and other options.
- 3.73:1
- 4.10:1
- 4.30:1
Note: The exact ratio for a specific vehicle should be confirmed on the axle tag, window sticker, or by decoding the VIN/build sheet, as manufacturers used different gears across trims and packages.
How to verify the exact ratio on your Tundra
To know the precise axle ratio for a particular 2014 Tundra, use the following verification steps.
- Inspect the differential housing for a stamped axle code or tag. The code can be cross-referenced to a ratio in Toyota's documentation or a reliable aftermarket reference.
- Check the vehicle’s door jamb or glovebox sticker for axle data; some models list Rear Axle as a separate line with the ratio.
- Consult the original window sticker (Monroney) or the build sheet if you have access to the factory documents or a dealer database; the ratio is sometimes listed as Rear Axle or Ring Gear Size.
- If you can access the vehicle’s VIN, use Toyota's official VIN decoding resources or trusted third-party databases to determine the exact axle configuration.
With the exact ratio confirmed, owners can plan towing, maintenance intervals, and any performance expectations accordingly.
Towing considerations and performance impact
The rear-axle ratio influences torque, acceleration, and fuel economy. A higher numerical ratio (e.g., 4.30:1) generally provides more low-end torque for towing and hauling but can reduce highway fuel efficiency and increase engine RPM at cruising speeds. A lower numerical ratio (e.g., 3.73:1) tends to improve highway fuel economy and quieter highway operation but offers less torque on steep grades. Always match the ratio to your typical use case and check manufacturer recommendations for towing capacities.
Summary
The 2014 Toyota Tundra did not come with a single rear-axle ratio across all models. The truck offered several ratios—commonly 3.73:1, 4.10:1, and 4.30:1—selected based on drivetrain and trim. To know your exact ratio, consult the axle tag, window sticker, VIN/build sheet, or ask a Toyota dealer. This knowledge is essential for towing planning, maintenance, and resale accuracy.
