"Stock suspensions typically offer a constant rate spring and little or no adjustability. High-end suspension gear has a variable rate spring at a minimum, which means that the spring resists the force more powerfully the more it's compressed. What that translates to for you, the rider, is a spring that may offer a better look for your bike, and a bike that reacts appropriately over gentle bumps or huge teeth-clickers.

As far as fork springs are concerned, one could get drop-in springs to change ride height, or variable rate kits with spacers and hardware, drop in cartridges, or cartridge emulators for those who are more budget conscious. Air-over-hydraulic conversion kits are available, as are straight air-ride suspension, which is the cream of the crop: adjustable ride height at will, soft or hard as you like it, and independently adjustable to make your trail measurement perfect." - Lemmy


For the better half of the 20th century, Harley-Davidson motorcycles were rigid bone-shakers. Today, owners can install Harley suspension components on their rides and enjoy something that original HD trailblazers could have never imagined. Whether your factory rear shocks have left you sore in the saddle or it just doesn’t look and feel the way you’d like it to, find reprieve for your road-weary rear here at RevZilla. We stock the best selection of aftermarket suspension upgrades on the web, including rear shocks, progressive wound fork springs, cartridge kits and related parts.

Harley-Davidson Shocks and Suspension Upgrades

For most Harley riders, one of the top reasons to consider suspension upgrades from stock is to change the way the bike sits and looks. Want to slam the ass end of your Softail down until the fender hugs the tire? Look into some shorter shocks, a lowering kit, or the ultimate: a touring suspension upgrade so you can create the ride you want that’ll truly go the distance. Want to play chopper and jack the front end up to the moon until you feel like Fonda? Dip a toe with some fork tube extensions.

Just remember, if you change the ride height, you may need either a shorter or longer kickstand (or a jiffy stand extension) to make the bike lean over properly when parked. Changing ride height isn’t the only way to overhaul your bike’s look and give some shine to your suspension. RevZilla carries several options for different finishes for fork tubes, fork boots and shrouds, fork lower covers and skins, shaved fork legs that look sleeker, raked triple trees, and frame inserts to dress up your bike’s look.

Or make a real investment in the enjoyment of your ride with heavy duty shock absorbers and springs for riding 2-up or fully loaded, high-performance piggyback reservoir shocks & monotube fork cartridge kits, preload adjusters, fork braces, fork seals, rebuild kits and more! If it fits on a Harley-Davidson, Softail or otherwise, and comes between you and a bump in the road, you can find it, fix it, replace it or upgrade it at RevZilla.com.
