What is axle ratio Ford?
The axle ratio refers to the gears in the truck’s differential, which is a mechanical device that links the rear axle to the driveshaft and then the engine. Four-wheel-drive trucks will have a matching ratio in the front axle’s differential.
Is a 3.55 axle ratio good?
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.
What is a good axle ratio?
Two common base axle ratios for trucks are 3.08 and 3.42. A 3.73 ratio is suitable for regular light towing. If you plan on towing a fifth-wheel trailer or anything heavier than 5,000 pounds, you should consider a 4.1 axle ratio. A 4.1 ratio allows a towing vehicle to start moving without as much throttle.
What is the best axle ratio for a Ford f150?
Axle Ratio When choosing your F-150, knowing that a 3.73 ratio provides much more towing power than a 3.55 or 3.31 ratio is crucial to achieving the capability you desire. Basically, the higher the ratio is, the more power you will get from your engine. Conversely, a higher ratio will lower a truck’s fuel efficiency.
What is the difference between 3.73 and 4.10 axle ratio?
A 3.73 is a higher gear ratio for half ton pickups its not the best gear for pulling trailers, now the 4.10 gears come stock from the factory on newer trucks and is one of the best rear end gears to use if you plan on pulling a trailer. These both vary by fuel mileage consumption so choose wisely.
Which is better 3.31 or 3.55 axle ratio?
Normally, the 3.31 would get you better gas mileage, on highway. But, with the 3.55 you will get a bit more pulling power so less time at higher RPM to get your trailer moving and when going uphill. If most of your towing is flat highway, the 3.31 should do you fine.
Can I change my axle ratio?
Luckily, some tuners, such as Sharkwerks, can alter the transmission’s gear ratios to improve acceleration and shifting frequency. There’s also the axle ratio to consider. As with the transmission, changing the axle ratio changes vehicle performance. A higher ratio means better acceleration, but worse efficiency.
Does a higher gear ratio mean more torque?
In general, a lower final drive ratio will lead to less torque at the wheels but a higher top speed. Meanwhile, a higher ratio will result in the opposite, i.e. more torque at the wheels but a lower top speed.
