Öhlins STX 36 Blackline rear shocks for Harley-Davidson Touring, 1990-2021. A premium upgrade over the OEM rear suspension, engineered for ride comfort, control, and long service life on the road.

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

The Blackline series is Öhlins' Harley-specific finish on the STX 36 platform — all-black anodized hardware with gold detailing. This dividing-piston configuration integrates the reservoir into the shock body for a clean profile and adds rebound damping and length adjustment. Spring rate is preset for a 250-575 lb combined rider + passenger + cargo weight range.

Features

• High-pressure nitrogen-charged monotube design with 36mm piston
• Dividing-piston design with reservoir integrated into the shock body (slim profile, no external hose)
• Adjustable rebound damping and shock length
• Pin-tool spring preload adjustment
• Fixed spring rate for a 250-575 lb combined loaded weight range
• 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 shock absorbers
• Pre-installed springs matched to the 250-575 lb weight range

Installation Notes
