A Sputhe Engineering Chassis Stabilizer (Posi-Trac) System is undoubtedly one of the best investments your can make for your Dyna
Dynas are notorious for the " DEATH WOBBLE " or that low tire pressure feel you get when cornering. This instability is due to Harley's poorly designed Dyna chassis.
The powertrain is mounted into the frame and supported by two centralized rubber mounts and a stabilizer link up top. Your swingarm and rear wheel assembly is mounted to the transmission case and not your frame. The offset weight from your primary drive, the twist or movement of the powertrain under torque, flex of the rubber mounts and more all lead to your rear wheel assembly mirroring the movement of the powertrain and causing these all well to known poor handling conditions and keep the rear well from being centered and inline with the chassis being there is no lateral support.
In 05' Alan Sputhe took a pantended design concept for the well know motorcycle engineer Eric Buell (designer of Buell motorycles and the infamous FXR) and put his own twist on it to solve the this handling problem for Dyna models.
This bolt on stabilizer mounts to your frame and to your rubber isolator mounts then attaches the two together with an adjustable linkage for alignment purposes and lateral stabilization. While still allowing the mounts to dampen and the powertrain to move up and down, it will prevent the unwanted side to side movements of flex.
