Q?

Q?

How do I know if I need spacers?

A.

In many cases, the need for spacers can be eliminated by turning the positively dished wheel around. However, PolyTech LLC can supply a spacer that moves the tire out 4 inches. You can determine the need for these spacers by measuring from the center of the R1 tread to the closest interference point. This interference point could be the driveline or the pivot leg. RAAFT 525/526 needs a minimum of 10 inches from the center of the tire. RAAFT 700 needs a minimum of 13 inches from the center of the tire.

Q?

Does it hurt the tracks to run in existing ruts?

A.

Yes, existing ruts should be filled whenever possible. Running in existing ruts adds a great deal of extra stress to the track, the wheel, and the gearbox and this stress will shorten the life of the track. This will be directly related to the amount of time the track is run in these conditions. However, many people choose to run in existing ruts because of the tracks ability to close the ruts and/or because it is often difficult to fill the ruts in some places.

Q?

What model of RAAFT Track is best for existing ruts?
