Nonononono....
Low means the drive wheel(s) are spinning slower than other gearings in relation to the engine, with more torque.
High means the drive wheel(s) are spinning faster than other gearings in relation to the engine, with less torque.
That's the best I could explain it. But, 6 to 1 (6/1) means the engine is spinning 6 times to turn the wheel once, and 4.86/1 means the engine is spinning 4.86 times to turn the wheel once.

6/1 is lower than 4.86/1.

To lower the gear ratio with a jackshaft you need a bigger input sprocket and a smaller output sprocket. Someone here can help you with the specifics.
