I actually bought a tube of lithium grease from canadian tire. I used that. Yes the spring is longer by a few inches. The stock spring guide doesn't allow turning so much and when you cock the rifle and the spring is compressed it turns. So its making it harder to cock. Dont use to much lithium grease but a nice coat on the oring will suffice. You could also use a teflon cylinder to make it easier to cock.
