An American Legend Meets Legendary Power

The icon of American V-Twin motorcycles–the Softail®–with its long front forks, authentic styling, nostalgia and swagger. All great stuff, right? Combine the unmistakable look of these legendary bikes with the unmistakable power of a ProCharger Intercooled Supercharger System and get ready to grow that legend even more by bolting on 40+ additional horsepower.

ProCharger has substantially raised the performance bar. ProCharger HO Intercooled systems and tuner kits are not only the easiest, quickest and most cost effective ($/hp) method to increase performance on stock and lightly modified V-Twins, they also take modified V-Twins to performance levels never previously achieved on pump gas. Softail with a high-performance edge. Cool air is better. With engine-friendly intercooled boost, you can run stock timing and 91 octane fuel on most existing motors without having to fight detonation. Stock or modified, nothing else even comes close.
