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 longer 13in (338mm) emulsion configuration — entry-tier in the STX 36 Blackline series and the most accessible price point in the Sportster lineup. The emulsion damper is preload-adjustable only (no damping or length adjustment), and the longer length suits riders wanting a slightly taller rear stance.

Features

• High-pressure nitrogen-charged monotube design with 36mm piston
• Emulsion damper design (single-tube, no separate reservoir)
• Pin-tool spring preload adjustment
• 13in (338mm) length — longer than stock for a taller rear stance
• Preset spring rate for the application — no damping or length adjustment
• 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 Emulsion shock absorbers
• Pre-installed springs for the application
• Preload adjustment pin tool

Installation Notes

• Direct bolt-on replacement for the OEM rear shocks. The 13in length is taller than stock and will raise the rear of the bike slightly — confirm this is the intended use case before ordering.
• Initial sag setting is recommended after install.
• This is the entry configuration in the Sportster STX 36 series. Riders carrying heavier loads or wanting damping adjustment should consider the dividing-piston (HD 751) or fully-adjustable piggyback (HD 752/756) variants.
