SPUTHE POSITRAC DYNA CHASSIS STABILIZER 1991-2017

For Harley-Davidson Dyna riders looking to improve stability, control, and safety, the Sputhe PosiTrac Dyna Chassis Stabilizer is one of the most effective upgrades available. Designed for all Dyna models from 1991-2017, it delivers a dramatic improvement in handling, especially during high-speed riding and cornering.

A common issue with Dynas is lateral isolator flex, which causes swing arm deflection. This results in instability at the rear end of the bike, particularly under hard acceleration or aggressive cornering. Sputhe’s PosiTrac system completely eliminates this problem by stabilizing the drivetrain and swing arm relative to the frame.

The PosiTrac system includes front and rear stabilizer links with brackets, which, together with the stock top stabilizer, create a plane that maintains perfect alignment of the steering head and rear axle under all riding conditions.
