From full frame modifications to custom swingarms, turbo kits, and precision engine upgrades, each project is tailored to the rider’s specific style and needs. Our goal is to deliver motorcycles that not only turn heads but perform at the highest level, whether on the road, the track, or during a stunt show.

Frame and Suspension Modifications

Optimizing your Harley for superior handling and control is key, whether you're hitting the streets or pushing limits in the stunt world. We offer expert custom frame modifications and suspension tuning to enhance performance. Our advanced Harley Davidson suspension systems, including the Nowaskey Dual Adjustable shocks with over 80 clicks of compression and rebound adjustment, provide precise tuning for ultimate stability and performance. No matter the riding style, our suspension upgrades are designed to give you full confidence on the road or in the stunt lot.

Engine Upgrades and Turbo Kits

For riders who crave maximum power, we specialize in high-performance engine modifications and turbo kits. Our custom builds often include Trask Turbo kits, designed to boost your Harley’s horsepower and torque, turning your bike into a performance powerhouse. Whether it's for stunt riding or racing, our turbo setups deliver explosive power and acceleration, ensuring your Harley outperforms the competition.

Custom Paint and Finishes

Beyond performance, we believe in delivering flawless aesthetics. We work with top industry painters and powder coaters to provide custom paint jobs that complement your bike’s performance upgrades. From bold, vibrant designs to sleek, understated finishes, every detail is meticulously crafted to make sure your Harley looks as aggressive as it rides.
