DODGE/DODGE RAM FINAL DRIVE RATIOS

Gears Under/Overdrive Find your transmission and rear gear multiplier below. The Final Drive Ratio shows you how many times the engine turns for one complete turn of the tires. This Final Drive number is also your torque multiplier when in that gear. GEAR VENDORS reputation for being the best is because of its sophisticated planetary construction. This means GEAR VENDORS is the only auxiliary intended as a GearSplitter behind automatics and the nicest to work behind both automatics and manuals. You are able to shift half gears that keep the engine in the power. Any auxiliary that requires you to let off the accelerator or is not intended to shift frequently is not going to give you this performance.

There is not room here to cover all the details so call the factory to discuss the full benefits demonstrated on these charts.
