Do you want a higher axle ratio?
A numerically higher axle ratio provides a mechanical advantage to send more of the engine’s available torque to the rear tires (and front tires, in a four-wheel drive vehicle), but you pay the price at the fuel pump. So, a truck with optional 3.73 gears will tow a heavier trailer than one with 3.55 or 3.21.
What differential ratio do I need?
Higher ratios are better for freeway driving since they run at lower RPM’s and offer better fuel economy. If you originally had 3.07 gears you need a ratio that is approximately 17% lower, such as 3.55. If you want to increase off road performance you might want a 4.10 or lower ratio.
What is a good gear ratio for hill climbing?
If you don’t want to stray out too far, a 46/17 to 42/17 are good gear ratios for smaller and occasional hills. These gear rates are considered a good middle ground that can be used in flat and hilly areas. However, they are not suitable for climbing very steep or long hills.
Is 3.42 or 3.73 better?
The 3.42 is fine for towing smaller boats, plus you will get better gas mileage for everyday driving. If I were towing frequently on hilly roads, I might would go for the 3.73 for better gas mileage while towing, but the 3.42 should be fine with a 205.
What gear do pros climb in?
Pros often use a 55×11-tooth high gear for time trials. On flat or rolling stages they might have 53/39T chainrings with an 11-21T cassette. In moderate mountains they switch to a large cog of 23T or 25T. These days, they’ve joined the big-gear revolution like many recreational riders.
What’s the F / D ratio for a 5 spd car?
3.46:1 for 5-spd manual, 3.27:1 for 5-spd auto. Other f/d ratios across the W202 range were 3.91/3.92, 3.67, 3.23/3.27, 3.07 and 2.88. Remember to take the diff and speedo as a set. QUOTES FROM CONSTERNATIUS: “Inside every small problem is a big problem screaming to get out.” 3.46:1 for 5-spd manual, 3.27:1 for 5-spd auto.
How is tire size and differential gear ratio related?
The following chart of Tire sizes and axle gear ratios are meant to give a general idea of the relationship between the differential gear ratio and the tire size and what effect the ratio has on power output and fuel economy.
What is the diff ratio for Hilux diesel?
The diff ratio required is whatever closest is available to 4.6 Hilux diesel = 4.88 Hilux petrol = 4.5
Is the 2.28 ratio good for fuel economy?
“A direct transmission paired with a fast ratio like a 2.28 may be perfect for fuel savings. But if the fleet travels in the mountains at all or uses the truck less than 80-85% linehaul in top two gears, then the 2.28 may not be ideal and actually hurt the fuel economy of the fleet.
