These Ring & Pinions are designed to run quiet and last longer than other aftermarket gear sets. They are easy to set up and we make sure that they meet LCE's high standards. The 7.5" differential is commonly found in 2wheel drive trucks and 4wheel drive front axles with independent front suspension.
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.
Gear ratio is calculated by dividing the number of teeth on the ring
gear by the number of teeth on the pinion gear. The higher the number,
the lower the ratio: a 5.29 gear has a lower ratio than a 4.10 gear.
With a lower gear ratio the drive shaft (and thus the engine) turns more
for each revolution of the wheel, delivering more power and torque to
the wheel for any given speed. Lower ratios are generally desirable when
going off-road. Higher ratios are better for freeway driving since they
run at lower RPM’s and offer better fuel economy.
Changing tire size affects the final drive ratio. Switching from a
30" tire to a 35" tire changes the final drive ratio by about 17%. This
may drop the engine out of its' "power band" and result in poor
performance and fuel economy. To restore performance you must change the
gear ratio to compensate for the change in tire size. 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.
