Spring Main Torque/Contra GY6 50cc to 250cc

Regular price $12.00

Main Torque (Contra) Springs for your GY6 50cc through 250cc Imported vehicle.

The Rear Torque Spring is in charge of how quickly you shift from Slow to Top speed.

A heavier spring will get you a noticeable increase on low end torque by stalling your takeoff just a little and has a nice downshift when you let off the gas which is Great for faster cornering!

Most STOCK VEHICLES come with a 1000RPM main spring.
The higher the number, the stiffer the spring, the more rpms you'll get at takeoff.
