Tuff Country EZ-Ride Suspension offers the new
adjustable carrier bearing drop brackets to help
eliminate any rear drive line vibration that may occur
in a vehicle that has had an after market lifted kit
installed. Due to the stock vibration that may occur,
Tuff Country EZ-Ride Suspension can not guarantee
that all vibrations will be eliminated. If any questions
occur during installation, please feel free to contact
Tuff Country or your local Tuff Country Dealer.
