Traction-Lok Axle (If equipped)
This axle provides added traction on slippery
surfaces, particularly when one wheel is on a
poor traction surface. Under normal conditions
the Traction-Lok axle functions as a standard
rear axle.
Extended use of other than matching size tires
on a Traction-Lok rear axle could result in a
permanent reduction in effectiveness. This loss of
effectiveness does not affect normal driving and
should not be noticeable to the driver.
To avoid injury, never run the engine
with one wheel off the ground, such as
when changing a tire.
