Progressive Suspension 444-4060C 444 Series Chrome Heavy-Duty Rear Shock Absorbers 11.5" - Pair

The Progressive Suspension 444-4060C is a pair of chrome, 11.5" heavy-duty rear shock absorbers built for serious riders who demand superior performance and comfort. Engineered for riders weighing 250 lbs. or more, or bikes frequently operated at or near maximum load capacity, these shocks deliver where stock suspension falls short.

At the heart of the 444 Series is Progressive Suspension's proprietary, patented Frequency Sensing Technology (FST) — a breakthrough damping system that senses the frequency of each bump and automatically adjusts damping in real time. Whether you're rolling over small road imperfections or hitting larger obstacles, FST distributes oil through internal ports accordingly to absorb the impact and maintain a smooth, controlled ride.

Key Features:

• Frequency Sensing Technology (FST): Proprietary patented system that dynamically adjusts damping automatically as you ride
• Deflective disc valving for precise, consistent damping response
• Hand-adjustable spring preload: Top-mount threaded preload adjuster — no special tools required
• Progressive rate springs: 165–205 lb/in spring rate for a progressive, predictable feel
• High-pressure gas charged: Ensures fade-free, consistent performance mile after mile
• Machined billet aluminum end caps for a premium, durable finish
• Chrome finish for a classic, polished look
• 11.5" extended length — may alter head angle slightly for quicker steering response
• Hand-built, tuned, and dyno tested at the factory
• Sold as a pair
• Limited Lifetime Warranty

The heavy-duty rating makes the 444-4060C ideal for bikes regularly ridden two-up, with luggage, or hauling cargo. These shocks are a direct bolt-on upgrade over worn or inadequate stock units, transforming ride quality and handling under demanding conditions.
