Which gear ratio is faster?
Which gear ratio is faster?
A lower (taller) gear ratio provides a higher top speed, and a higher (shorter) gear ratio provides faster acceleration. . Besides the gears in the transmission, there is also a gear in the rear differential.
Is 3.23 a good gear ratio?
The engineers likely chose the numerically low gear ratio for fuel economy reasons. A later swap to a four-speed and 3.23 rear gears woke up the performance of the car considerably. Yes, highway rpm increased as well, but I rationalized it by deciding that 3.23 gears provided a good balance of performance and economy.
What gear ratio is best for fuel economy?
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.
Are 3.73 gears good for highway?
Rear end gears (2.79’s, 3.00’s, 3.25’s, etc) are great for freeway driving, bit not good for 0-60 MPH or accelerating from a dead stop. Shorter gears (higher numbers) are much better suited for accelerating, such as 3.55, 3.73, 3.91’s, 4.11’s etc. Always remember, for very “give” there is a “take”.
Does bigger tires change gear ratio?
If the Tires Are Bigger, the Gears Should Be Lower. Going to lower gears (ironically, a numerically bigger ratio) will increase the rpms of an engine (taking for granted the same diameter tire and going the same speed).
Is 3.55 or 3.73 gears better?
3.55 will give you a little better gas mileage on the highway and slightly more highway oriented performance. 3.73 may be better for towing, lower end power (off the line acceleration), and may result in worse gas mileage on the highway.
Is 3.55 a good gear ratio?
For example, a truck equipped with 3.55:1 axle gearing will accelerate faster than one equipped with a 3.31 axle ratio. BEST TOWING RATIO: In general, the best towing axle ratio for most of the post-2010 pickups is in 3.55 or 3.73. Those ratios provide very good acceleration with gas V-8s and diesels.
Is 3.73 gears good for towing?
FACT: A 3.73 axle ratio is ideal for towing heavy loads on flat terrain and will produce increased fuel economy during steady-state, long-distance highway driving.
Is 3.42 or 3.73 better?
3.73 is 9% higher than 3.42. That means your RPMs at any given speed will be 9% higher. You should be able to accelerate about 9% faster, in the lower gears at least. Your maximum speed in each gear will decrease by 9%.
Are 3.42 gears good for highway?
The 3.42 gears do run well on the highway though, not much over 1900 rpms at 70.
Is a 3.42 gear ratio good?
Lower numeric axle ratios may help reduce how much an engine has to work while cruising at highway speeds, and can potentially help improve fuel economy. For instance, the 3.42:1 ratio included on many Canyon V-6 and Sierra 1500 models offers a good all-around blend.
Are 3.42 gears good for towing?
You won’t have any trouble towing you rig with a 3.42 rear end. You may need to stay in Drive rather than overdrive when pulling, but that was a requirement of Chevy up until 1997 anyway. In a half ton truck, you will only find 3.73 gears anyway. You have to go to 3/4 ton to get the 4.10 gears.
How much can a 5.3 L V8 tow?
5.3L V8 Engine — produces 355 hp and 383 lb-ft of torque. Towing capacity is boosted to 11,600 pounds.
Can you change the gear ratio on a truck?
You can change the axle ratio, and you can do it rather easily. Quite a few members here have gone from one ratio to the next. People with 3.21 and 3.55s are going up to 3.92 and even sometimes 4.10. A lot of the 4×4 trucks you see here with lifts and larger tires have gone with 4.10 or 4.56.
Which RPO code is for gear ratio?
GM RPO Axle Code List (G)
| RPO | Axle Type | Ratio |
|---|---|---|
| GT4 | Rear Axle (5X1) | 3.73 |
| GT5 | Rear Axle (GT8) | 4.10 |
| GT7 | Rear Axle | 3.33 |
| GT8 | Rear Axle (GT5) | 4.10 |
What gear ratio do I have by Vin?
Check the bolts on the differentials. There should be a tag on one of them. The codes on that tag will tell you the gear ratio. The VIN will not give you gear ratios in most cases.
Can you tell gear ratio from Vin?
Identify the VDS section, the fourth through eighth digits of the VIN. This section typically includes information such as the vehicle model, engine size and body type. While not every vehicle manufacturer includes gearbox ratio information in the VDS, this will be where the information is found if it was included.
