Need some help! I am replacing the belt, drive clutch spring, ad driven clutch spring. Been surfing the net and trying to find a kit. Most replacement kits come with a new helix and new springs. The problem is mots only advertise for a 500 HO. Would it be OK to use this kit in a 400? It is used for trail riding and hunting. Should I just get the parts from the dealer? If the after market parts are close to the same price, then I'd much rather use them.

 

You have a 4stroke or 2stroke 400?
A 400 4stroke go with a Polaris white spring and the Aaen blue secondary spring and stock weights or if the lowend suffers go with 10MB weights
For the 2stroke go with Aaen green primary,Aaen blue secondary and S55 weights if not enough low end go with S58 weights

 

It is a 2002 Polaris Sportsman 4 stroke.

If I change out the helix, will it make that much of a improvement? Or will that be in the springs?

 

No need to change helix springs will do maybe weights too depending on how it feels with the springs and what you are taching
