812 Series Shocks And Forks - Sporty Lowering

812 Series Shocks And Fork Lowering From Progressive Suspension

By Jordan Mastagni, Photography by Ernie Lopez, Jordan Mastagni

Low equals cool; at least, in our opinion. After test riding the Nightster (Vol. 39 No. 9), we kicked around a few ideas of how to achieve a similar look on our stock '06 XLC Sportster.

After perusing the Internet and various catalogs, we came to the conclusion that Progressive Suspension's new 812 Series shocks (MSRP: $349 per pair) would be the perfect fit for what we had in mind. The 812s are 11 inches as opposed to the 12-inch stock shocks, and feature a five position pre-load adjuster so that you can play around with the riding style you prefer. With just a couple of turns you can increase the pre-load for a more aggressive ride or decrease pre-load for a nice and spongy leisurely stroll. Plus, the chromed 812s are available in two different spring-can designs: Baloney-cut or Double-cut.

To complement the drop in the rear, we compensated by lowering the front forks about two inches with Progressive's Fork Lowering Kit (MSRP: $102) so that we would still be all right as far as ground clearance was concerned without grinding the pegs to a bare nub-at least not right away.

We brought the stock Sportster into Progressive's shop, and the install took roughly an hour and a half: The shocks about 20 minutes, and the fork legs about an hour. We were amazed at how simple the install was; even if you aren't playing with a full deck you still should have no trouble doing the same thing in your garage. Enjoy!

    6. Then he adjusted the preload with the provided wrench. The shocks are equipped with a five position preload adjuster and come pre-set at the lightest setting; you can simply adjust the preload to better fit your riding style. Now, take your new shocks for a spin and play around with whatever setting you desire. If you bottom out, Progressive recommends adjusting to a higher/stiffer setting. Increase by turning clockwise, decrease by turning counter-clockwise.
