1991-2017 Harley-Davidson Dyna Öhlins STX 36 Blackline 12in Piggyback Reservoir Shock (Pair)

Öhlins STX 36 Blackline rear shocks for Harley-Davidson Dyna, 1991-2017. A premium suspension upgrade over the OEM rear shocks for the full Dyna FXD platform run, with the all-black Blackline finish and the proven STX 36 damping platform tuned for the Dyna chassis.

Sold as a complete pair (left and right rear shocks).

This is the fully-adjustable premium configuration in the 12in Dyna Blackline series — adds compression damping adjustment and a piggyback external reservoir for consistent damping under sustained spirited riding. Recommended for riders who want the full Öhlins tuning range.

Features

• High-pressure nitrogen-charged monotube design with 36mm piston

• 12in length — stock-equivalent for most FXD applications
• Pre-installed springs matched to the application
