What is diff ratio GU Patrol?

GU 4.5 Petrol = 4.11:1. GU 4.8 Petrol manual = 4.375:1.

What do diff ratios mean?

Differential Gear Ratio determines the number of times the drive shaft (or pinion) will rotate for each turn of the wheels (or ring gear). So if you have a 3.73:1 gear ratio the drive shaft turns 3.73 times for every turn of the wheel.

Can I change my diff ratio?

To counteract the effects of larger tires, you can change the gears in your differential(s) to increase the ratio of how many revolutions of the driveshaft it takes to make one full revolution of the wheel (raising the engine rpm at the same speed).

How do I know what Hilux Diff I have?

they generally have a sticker with “LSD” attached near the filler bung. aside form that – vehicle chassis plate. will prolly only give a diff series though.

How do I choose the right gear ratio?

To find the ideal selection, multiply the final drive ratio by the redline speed in fourth gear (152 mph) and divide that by the top track speed (140 mph). This would yield a theoretical 3.33—which is close enough to the nearest available final drive ratio of 3.36:1.

Is a bigger differential better?

Higher ratios mean the engine has to run faster to achieve a given speed. Lower ratios allow the engine to run more economically to maintain that given speed.

What gear ratio is best for speed?

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.

Should I get 3.73 or 4.10 gears?

4.10s are going to accelerate faster and decelerate faster on lift. However the trade off is greater fuel consumption per mile driven and higher engine speed per given road speed. In basic terms the 4.10s will feel quicker and 3.73 will feel faster. Do you plan on towing or moderate to aggressive off-roading?

Is 3.55 or 3.73 better?

PERFORMANCE: The larger the axle ratio number, the quicker the truck will accelerate. For example, a truck equipped with 3.55:1 axle gearing will accelerate faster than one equipped with a 3.31 axle ratio. Similarly, a pickup with a 3.73 axle ratio will be faster than one with 3.55s.

What gear ratio does Toyota Tundra have?

4.30
And helping to deliver the power produced by the Tundra’s 5.7L V8 is the specially designed rear differential and its massive 10.5-inch ring gear. This enables the 2020 Toyota Tundra to use a 4.30 rear axle ratio to amplify and transfer torque where you need it most.

What is the best gear ratio for a front diff?

Front and rear diff centres. 4.625 Ratio. A common upgrade when moving to larger tyre sizes is to fit the highest factory ratio available (4.625:1) to correct driveline gear ratio. Upgrading from 3.9 or 4.1 gears to 4.625will give you better acceleration, and improved control when engine braking offroad.

What is the rear diff ratio for a landcruiser?

The diff ratio required is whatever closest is available to 4.6. Standard diff ratio’s. Landcruiser 40 = 4.11 Landcruiser 60 = 4.11 Landcruiser 70 & 75 = 4.11 Landcruiser 78 manual R151F (split transfer case) = 4.3 Landcruiser 78 manual H150F = 4.10 Landcruiser 80 manual & auto = 4.10 Landcruiser 100 manual = 4.3 Landcruiser 100 auto = 3.9

What do the numbers on the Rear diffs mean?

Common across all GU’s. HG – This indicates the rear differential fitted. HG indicates a H233B rear diff, with a 233mm crownwheel. 39 – This indicates the diff ratio fitted at the factory. This number is rounded to 2 decimal places so is not completely accurate.

What is the diff ratio for a Toyota Hilux?

The diff ratio required is whatever closest is available to 4.6 Hilux diesel = 4.88 Hilux petrol = 4.5
