The Dyna® "Dragon" Swing Arm Chassis for Single and Twin Cam 'A'® engines is not a stock replacement frame for stock Dyna Models.

This frame will take a top tube stretch of 3" maximum and a front leg stretch of 4" with any neck rake. The frame takes all stock OEM Dyna® front, rear, and top motor mounts. The frame is set up with Softail seat mounts and uses a custom seat, stock OEM swing arm bearings and pivot assembly. You can use your stock OEM axel and adjusters or use the Atlas custom axle adjusters. The frame uses the 412 series gas shocks 12" which gives you a 6" frame to ground clearance and 4 1/2" oil pan to to ground clearance. The swing arm requires the use of the atlas custom rear caliper and hanger kit, not stock. A stock Dyna® belt guard may be used. The frame takes a 180 rear tire with stock Dyna belt, 200 with Harley® 1 1/8" belt or chain drive. When using the Harley® 1 1/8" belt, you need to change the transmission pulley to 1 tooth larger than stock.
