## Overview

The Progressive Suspension 444-4073B is a 13.5-inch rear shock designed specifically for Harley motorcycles, featuring patented Frequency Sensing Technology that automatically adjusts damping for superior ride comfort. With hand-adjustable preload and options for standard to super heavy-duty springs, it offers customizable suspension tailored to rider weight and style. Finished in durable black, this shock balances performance and style, delivering a cost-effective upgrade praised for significantly improving ride quality.

## Description

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 (up to 250 lbs.), heavy-duty (250+ lbs.) and Super heavy duty (touring models only - 350+ lbs.).

Review: Great improvement in the ride. - I purchased these shocks to improve the ride on my 2012 Triglide. The stock shocks never were any good. My wife likes them because they made the ride better. There is no system available that will be perfect but they do improve the comfort. This is not the most expensive option out there but its cost effective at half the price of some others.
Review: Rough ride - Heavy duty way to strong rough ride... should have bought the standard...

### ⭐ Rough ride
*by M***K on May 27, 2025*

Heavy duty way to strong rough ride... should have bought the standard...

### ⭐⭐⭐⭐⭐ Major improvement in ride
*by C***E on October 25, 2020*

I bought these for my 2017 Harley ultra glide classic trike. Having a motorcycle lift made the job a lot easier. The shocks are well worth the money whether you ride long-distance or just short commute in town. After removing the stock airbags & installing the progressive shocks Texas roads, cornering, highway rides, “textured” roads, dips and bumps were a lot more comfortable!!! You need these for your bike!!!
