The Thule Racks 955 No Sway Cage Hitch Bike Rack Accessory is the easiest way to keep your bicycles stable when in transit. Thule 955 No Sway Cages mount to the T3 Cradles and eliminates any bike swing/sway - bikes don't hit each other or the vehicle. Sold as a two-pack (each bike requires one 955 No-Sway Cage, so a 2 pack is good for two bicycles.). For use on the Thule 964 Revolver, 954 Ridgeline & 912/914/915 Roadway series hitch bike racks (Revolver & Ridgeline come with 955 No-Sway Cages already included). Also compatible with discontinued 998XT Trailblazer, Hitching Post Pro series & Expressway series. 955 is designed to work exclusively in combination with the Thule T3 cradles. Eliminates need for the Thule 950 Zip Stick II anti-sway device (however, Thule Parkway series bike rack cradles are not compatible with 955 No-Sway Cages and require 950 Zip Stick II instead.) No Sway Cages sold as a 2 pack (each bike requires one No-Sway Cage, so two pack is good for two bicycles.) Thule Racks Lifetime Warranty!
