The most important part of having a lowrider motorcycle is having it sit low. While there are several methods to lower the rear of motorcycle, the most common is the use of shortened shocks. Our project 1989 Electra Glide Sport FLHS has been running Burly Slammer rear shocks for more than two years without a single problem. The only downside to them is they are designed to be an inexpensive way to lower the bike, while still retaining some bit of suspension.
We found the limits of the Slammer Shocks after a few two-up rides and our asses seeing some daylight on some rough-and-tumble roads during the Hot Bike Tour.
To help regain some control, we decided to install Progressive Suspension’s 944 Series Ultra Touring shocks. They are available in two different lengths, including a 12.5-inch Ultra Low, which we chose.
Installation is extremely straightforward and could be accomplished by anyone using hand tools in a garage. The difference in ride quality is overwhelming and possibly one of the best investments you can make to your motorcycle. Gone are the bumps and jars, replaced with a much more controllable squat with substantially greater control.
Here’s our heavily modified 1989 Electra Glide Sport sitting low and pretty.

Tucked between the custom bags, you can see the Burly Slammer shocks that provided us with a couple of years of reliable shock duty.

First we removed both bags to gain access to the shocks behind.

Before removing the shocks, we unloaded the pressure off the shocks using a jack underneath the frame.

Remove both shocks by removing the top and bottom bolts. Raise or lower the bike using the jack to make sure the shock springs are not under tension.

Shown here are the shocks side by side. You can see the new Progressive 944s (left) are only slightly longer than the super short Burly Slammers (right).

Install the new shocks using the supplied hardware. Make sure and install them the correct side up according to the directions.

You might need to raise the bike using the jack to correctly line up the bolt-holes.

Before reinstalling the bags, with the help of an additional person, check and set the sag by measuring how much the bike lowers with the rider sitting on it. Make adjustments as necessary as per factory recommendations.

Finally reinstall the bags back on the bike. Our bags were custom to the bike, so we had to make a few adjustments to the mounting brackets to allow for the longer shocks.

Hidden away behind the bags, the new shocks are ready for duty. The longer shocks only raised the rear of the bike slightly, but the increase in handling was well worth it. New suspension designed specifically for your bike and the type of riding you do can be one of the best investments you can make.
