Progressive 412 Shocks For Harley Touring 1984-2005
Best Value Upgrade: Progressive 412 Shocks for Harley Touring (1984–2005)
The Progressive Suspension 412 Series Shocks are the most popular and cost-effective upgrade for the rear suspension of Harley-Davidson Touring models (FLH/FLT) spanning the Evolution and early Twin Cam eras from 1984 through 2005.
These shocks offer a significant improvement in damping control, ride quality, and handling over the often-tired or basic factory air-adjustable units, all while providing a customizable ride height.
🔑 Key Features of the 412 Series
Improved Damping: Features a double-wall steel body with nitrogen gas charging and multi-staged, velocity-sensitive valving. This delivers consistent, controlled damping that noticeably smooths out the ride compared to stock.
Adjustable Preload: Equipped with a 5-position cam-style preload adjuster (spanner wrench included). This allows the rider to quickly and easily adjust spring stiffness based on load (solo, two-up, luggage).
Progressive Rate Springs: Uses progressively wound springs available in two main options:
Standard Duty: For most average-weight riders (typically under 250 lbs total loaded weight).
Heavy Duty: Recommended for bikes operated at or near the maximum load rating over 50% of the time (e.g., frequent two-up riding, very heavy luggage, or riders over 250 lbs).
Finishes: Available in classic finishes like Chrome or Black bodies and springs.
Fitment Range (1984–2005)
The Progressive 412 Series is a direct bolt-on replacement for virtually all Harley Touring models in this range, including:
Road King (FLHR)
Electra Glide (FLHT)
Road Glide (FLTR)
Ultra Classic (FLHTCU)
The Progressive 412 Shocks provide a reliable, customizable, and affordable path to modernizing the suspension feel of your classic or early Twin Cam Touring motorcycle.
