How many gears are there in the traction Trailer?
If the whole is mostly Ping Lu words, that is the 9 file (high conversion speed), if the road is not good enough is the 12 file (generally 12 stalls, 6 speed and 6 speed), there is a special, that is the 16 file (8 low speed and high speed) 8.
You have a one-sided problem. It depends on what kind of road you drive
The first 1.5 files, four low speed, four high gear. Now twelve stalls, six low speed, six high speed.
