Öhlins STX 36 Blackline rear shocks for Harley-Davidson Sportster XL, 2004-2022. A premium suspension upgrade over the OEM rear shocks, with the all-black Blackline finish and proven STX 36 damping platform tuned for the Sportster chassis.

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

This is the fully-adjustable premium configuration in the 12in Sportster Blackline series — the only build with both compression and rebound damping adjustment, plus a piggyback reservoir for consistent damping under sustained spirited riding. Recommended for riders who want the full Öhlins tuning range and the visual presence of the external reservoir.

Features

• High-pressure nitrogen-charged monotube design with 36mm piston
• Piggyback reservoir design for consistent damping under sustained load
• Adjustable rebound damping, compression damping, and shock length
• Pin-tool spring preload adjustment
• 12in (296mm) length — stock-equivalent for most XL Sportster applications
• Pre-installed springs matched to the application
• Hard-anodized, CNC-machined components for corrosion resistance and consistent damping
• Fully serviceable and rebuildable — Öhlins services these in-house, and they are designed to be rebuilt rather than replaced over their service life.

What's Included

• Two (2) Öhlins STX 36 Blackline Piggyback shock absorbers
• Pre-installed springs for the application
• Preload adjustment pin tool

Installation Notes

• Direct bolt-on replacement for the OEM rear shocks. The piggyback reservoir extends outboard from the shock body — confirm clearance for aftermarket saddlebags, fender struts, or seat hardware before ordering.
• Initial sag setting is recommended after install.
