The Harley Trikes Tri Glide / Freewheeler Independent Suspension upgrade INCREDIBLY improves the riding and handling quality of your Tri Glide or Freewheeler. It begins by exchanging the rigid factory straight axle unit for the proven Harley Trikes Independent suspension assembly that rides and glides smoothly over the various road conditions. The upgrade also improves the ride height of the Trike and adds 2” to the wheelbase. Your stock drive belt, Cush driven pulley and differential gears are incorporated into the replacement suspension unit. The Trike body retains its stock location. The aluminum coil over adjustable shock absorbers and anti-sway bar will keep your Tri Glide or Freewheeler riding like a Cadillac and flowing through the twisty's like a Porsche!
