Diff Ratio for Subaru SVX
The differential ratio for the Subaru SVX varies depending on the model and location. The differential ratio for the Australian SVX is 3.7, while the US version has a ratio of 3.9. Additionally, it was mentioned that for a US WRX 5MT, a 3.545 rear diff is needed. Furthermore, there are discussions about changing the differential ratio, such as swapping from 3.9 to 4.44.
It’s important to note that the differential ratio can impact the performance and handling of the vehicle, so it’s crucial to consider these factors when making any modifications or replacements.

What is the best rear ratio?
For instance, a 3:31 gets better fuel economy than a 3:73. On the other hand, a 3:73 or perhaps a 4:10 will tow much more, while fuel economy greatly drops. The most popular rear end ratio in trucks today is the 3:55, which sort of averages towing power and fuel economy.
Does 3.73 gears make a difference?
In a sports car, 3.73 gears will offer better acceleration while retaining top speed when compared to 3.55 gears that come factory on many sports cars.
Is a higher or lower diff ratio better?
Fuel efficiency: A lower differential ratio requires fewer engine revolutions to achieve a given wheel speed. This means the engine works less and consumes less fuel, resulting in better fuel economy.
What gear ratio is a Subaru rear diff?
These gears are a multiplier only for the rear diff ratio. Subaru uses only 1.0 or 1.1 ratios for the transfer gears depending on the application. The 1.1 ratio has been used with certain applications using a 3.90 final drive ratio. With the 1.1 transfer ratio a 3.545 rear diff ratio is used (3.545 x 1.1 = 3.90).
What is a 3.73 rear axle ratio?
Axle Ratio Explained
It represents the number of revolutions the driveshaft must make to rotate the axle one full cycle. It is rendered in a ratio such as 3.73. 1 or 3.73. So if a truck has an axle ratio of 3.73:1 or 3.73, it means the driveshaft turns 3.73 times to spin the axle one full cycle.
Can you get gear ratio from VIN number?
Re: using vin to find gear ratio
The VIN number won’t really tell you gear ratio. It’ll tell you the engine, and sometimes only one gear ratio was available with a specific engine, but for 88 the L98 could be had with 2.77 or 3.27 gears.
What is the rear diff ratio for a SVX?
The SVX uses a unique final drive ratio (3.545:1), and no Legacy shares it. You would need to also replace the rear diff to match the AT.
What does SVX stand for Subaru?
Subaru Vehicle X
The suffix “SVX” is an acronym for “Subaru Vehicle X“.
Where do I find my diff ratio?
Check the Differential Cover
The axle may have a sticker, and on the differential cover, you might have a small metal tag that’s sticking out that will have the gear ratio stamped on it.
What is the difference between 3.73 and 4.10 gears?
What is the difference between a 3.73 and a 4.10 axle ratio? 4.10 gears will give you more toque for pulling at lower speeds, as it is lower geared, but it does cost you in fuel efficiency. I prefer 3.73, as it gives plenty of torque for pulling, but doesn’t cost you as much fuel mileage.
