Stage 1 Secondary springs are designed for vehicles equipped with 27”-29“ lightweight oversizes tires (not agressive mud tires).
Stage 2 Secondary Spring are designed for riding with oversized/heavy mud tires (28” - 34"). It reduces belt slipping and protects clutch for overheating, it gives better low-end power, torque and quicker backshift which results in crisp throttle response.
Stage 1 Secondary spring
27”-29” tires
-
For models equipped with 27”-29” wheels.
-
This will give you that just a little extra crunch, when using 1-2" bigger tires than stock.

This is compatible with almost all CFMOTO secondary clutches and every model with CVTech LP3 secondary clutch.
-
Helps to maintain the optimal CVT transmission performance when changing the tire size to bigger ones.
-
Gives more belt grip for big tires.
-
Slows upshifting and corrects the gear ratio with big tires.
-
Lower belt temp.
STAGE 2 Secondary Spring
28”-34” tires
-
For models equipped with 28”-34” wheels.
-
When you are using big and heavy tires, this is what you want to make those tires to spin, no matter what.
-
This is compatible with almost all CFMOTO secondary clutches and every model with CVTech LP3 secondary clutch.
-
Helps to maintain the optimal CVT transmission performance when changing the tire size to bigger ones.

Our secondary clutch spring helps to maintain the optimal CVT transmission performance when changing the tire size of the vehicle from standard. When installing larger diameter tires, it is recommended to change the clutch settings also. If the clutch settings are not changed, the clutch will try to engage too soon and the clutch changes the transmission gearing too early for the larger wheels, placing a heavy load on the clutch belt, which could end with a broken belt in the worst case.
If the clutch belt has broken for some reason, it has probably generated high heat in the clutch parts, which could also have an effect on the clutch (clutch)spring. A loose spring causes the clutch to engage too soon and the transmission gearing changes too early, which usually can cause the new clutch belt to break. So, it is recommended that the (clutch)spring in the clutch should be always replaced in pairs with a new belt. The function of the secondary clutch is to make the transmission heavier as the speed increases and the spring and helix inside it determine this event as desired.
If the ring size is changed to a larger than two inches constant, for example, it makes the constant really high on the clutch when accelerating, because then it tries to implement too much transmission too early. This can be easily remedied by replacing the clutch spring with a stiffer one, thereby slowing the growth of the transmission and creating additional belt pressure which increases belt grip.
To find the right secondary clutch spring for your ATV or UTV, visit our store or contact a regional dealer.
