Our Air Suspensions for FL, Dyna, and Trike models are engineered to compress to 10 ¼” and extend to 13”, while our Air Suspension for V-Rod models compresses to 10 5/8” and extends to 13”. We meticulously design our suspension systems using the factory extended and compressed lengths to ensure that the chassis remains within its normal geometry ranges as the suspension moves through its range of motion.

Maintaining proper geometry is crucial for factors such as belt tension and tire-to-fender clearances, particularly when the suspension is fully deflated or fully compressed. By matching the OEM compressed length with our shocks, we mitigate potential issues such as belt tension alteration or rear tire rubbing against the fender. Deviating from the OEM specifications could pose risks, such as a sudden loss of air pressure at speed, potentially leading to accidents due to rear tire lockup. Therefore, we prioritize safety by designing our shocks to provide ample clearance between the rear fender and tire, preventing such situations.

It's worth noting that some riders may attempt to achieve an extremely low riding stance by modifying suspension mounting points to have the frame rest on the ground when the suspension is fully deflated and compressed. However, we do not recommend these alterations with our suspension products, as they can compromise the integrity and safety of the system. Such modifications may introduce liabilities that we cannot assume, given the importance of adhering to factory specifications for optimal performance and safety.
