Trail Creeper Ring & Pinion 4.88 High Pinion 8"
Looking for a Ring & Pinion that you can rely on even on the most
punishing trails? We are proud to offer Trail-Creeper Ring &
Pinion Gears. These are the very same gears that have won multiple
championships on the W.E. Rock circuit and have proven themselves on
some of the most grueling off-road courses in the world.
Our Trail-Creeper gears are made from tool-grade 8620 steel and
heat-treated for maximum strength and wear resistance. The gear teeth
are cut using Gleason CNC hobbing machines & cutters. Gleason
gear-cutting technology produces an unprecedented level of accuracy and
surface finish, which allows the gears to transmit more torque and
improve fuel efficiency. The higher accuracy and surface finish also
produces a quieter-running gear set, which means they’ll work great on
the daily driver too.
If you’re looking for a Gear Set that’s easy on the wallet, but can
handle whatever you throw at it, look no further, because Trail-Creepers
are only available from Trail-Gear.
On Toyota trucks we recommend 4.88's for 33" tires and 5.29 for 35" and larger.
Fits 79-85 4WD Toyota axle 8" ring gear, and most 86-95 rear axles only.
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.
