I know this is a gross simplification, but this is a ratio of how many times the drive shaft (and thus the engine) turns in relation to the tire. The reason for a higher numerical ratio is to have the engine turning in it's "power" band. Most engines generate more power as rpm (revolutions per minute) increases, until it reaches a plateau, then it drops off. The idea of a higher ratio (numerically) is to put that power band to use where the driver needs it. Lower ratios (higher numerically) spin the engine faster for a certain speed, thus moving the power band to a lower vehicle speed. This is helpful in towing, and for faster acceleration. The downside is the engine will be turning faster at "highway" speeds, and not be as fuel efficient and will limit the speed the vehicle can run, as RP M's will be near maximum before drag/lift limits the actual speed.
3.55 turns of the input shaft to one turn of the ring gear and axle shafts.
These were the options in 2000: [DMC]=Axle Ratio - 3.21 [DMD]=Axle Ratio 3.55 [DMF]=Axle Ratio 4.10 [DMH]=Axle Ratio 3.92 These were the options in 2000: [DMC]=Axle Ratio - 3.21 [DMD]=Axle Ratio 3.55 [DMF]=Axle Ratio 4.10 [DMH]=Axle Ratio 3.92

Depends on each individual truck. Look in your glovebox....there is a label from the factory with parts codes on it. The one with G refers to your gear ratio/ ring & pinion. GQ1 -- AXLE REAR, STD RATIO GT4 -- AXLE REAR, 3.73 RATIO GT5 -- AXLE REAR, 4.10 RATIO GU4 -- AXLE REAR, 3.08 RATIO GU5 -- AXLE REAR, 3.23 RATIO GU6 -- AXLE REAR, 3.42 RATIO G80 -- AXLE REAR, LIMITED SLIP (POSITRACTION)
I believe the axle code is listed on a sticker on the end of the drivers door The axle code will correspond to an axle ratio Once a person knows the axle code , the ratio can be looked up
Axle code? there are usually labels or tags on the axle with ratio and part numbers on them.Axle code? there are usually labels or tags on the axle with ratio and part numbers on them.
the lower your rear axle ratio, the worse your mileage.
axle ratio cade for ford super duty”
The axle ratio on a 1969 Ford Mustang axle was 2.75:1
To check the rear axle ratio on your Suburban, you need to safely jack up the vehicle to get access to the the rear axle. Then there should be a metal tag on one of the bolts on the rear axle cover indicating the axle ratio. The ratio varies with different options and load capacities, so it's not the same for all Suburban's.
The ratio is on a tag on front and rear axle between 2 of the cover bolts
