Our Air Suspensions for FL, Dyna, Sportster, and Tri-Glide will compress to 10 ¼” and extend to 13”. Our Air Suspension for V-rod models will compress to 10 5/8” and extend to 13”. We design our suspension using the factory extended and compressed lengths to ensure that we do not put the chassis outside of its normal geometry ranges as the suspension extends and compresses. This is important when it comes to belt tension and tire to fender clearances when the suspension is completely deflated and fully compressed. Since our shocks fully deflated and compressed match the OEM compressed length, we know that belt tension won’t be negatively affected, and we won’t have issues with the rear tire rubbing the bottom side of the rear fender. If our shock length compressed was less than that of a stock shock, the potential issue that could arise would be a sudden loss of air pressure at speed, resulting in an accident because the rear tire would lock up. We design our shocks to have a compressed length that allows for clearance between the rear fender and the tire to prevent this situation from occurring. There is far too much liability to assume for us to offer something that is designed outside of the factory spec.

In many cases where riders are getting the bikes to sit drastically low, they are altering suspension mounting points to get the frame to lay on the ground when the systems are completely deflated and fully compressed. We do not recommend these alterations with our suspension products.
