Progressive Suspension PS-444-4048B 444 Series 12.5" Heavy Dut...
Our 444 Series Shocks feature a proprietary patented Frequency Sensing Technology (FST) that has the unique ability to dynamically adjust damping as you ride; what this means is whether you’re hitting the small or big bumps in the road, the shock distributes oil through ports accordingly to soak up the hit making for an ultimately comfortable ride. A top mount threaded preload adjuster allows for fine-tuning with a simple twist of the cap. 444 Series shocks are available in 3 configurations: Standard Weight, Heavy-duty (250+ lbs.) and Super Heavy Duty (Touring Models only - 350+ lbs.).
Every 444 shock is hand-built, tuned and dyno’d and include a Limited Lifetime Warranty.
Features
• Frequency Sensing Technology (FST) Allows the shocks to sense the frequency of a bump and automatically adjust damping for superior ride quality
• Deflective disc valving
• Adjust spring pre-load by hand, no special tool needed
• Progressive rate spring
• Standard or heavy duty spring rate and black or chrome finish
• Limited Lifetime Factory Warranty & made in USA
