Progressive 5046-100

The Progressive Suspension Quik Preload System (QPS) Upgrade Kit makes adjusting the preload on PS 444 Series and 944 Series shocks easier than ever before. With the QPS Upgrade Kit installed on 444 Series and 944 Series shocks, it's no longer necessary to take saddlebags off to adjust the sag when going from a single rider, to a two up riding configuration, and then back to a solo riding experience. This means the suspension can be set up for changes in weight load in less than a minute ensuring a perfect ride every time. With 30 complete turns of fine-tuning preload adjustment, the maximum performance of the suspension can be dialed in with a few twists of an 8mm socket. The QPS Upgrade Kit utilizes a sealed gear drive to smoothly adjust preload and offers the same range of preload adjustment as the original 444 or 944 series shock when it comes from the factory. As with the 444 and 944 Series shocks, the QPS Upgrade Kit comes with a Lifetime Limited Warranty.
