About Pro Design Racing
Pro Design Racing has built a four-decade reputation as one of the powersports industry's most respected names in performance engineering. Pro Design Racing has been engineering and manufacturing high-performance ATV, motocross, and watercraft parts since 1982, producing race-proven components built for riders who demand the very best in performance, reliability, and quality.
Unlike generalist parts suppliers, Pro Design focuses its expertise on a targeted range of performance-critical components — the kind that directly influence how an engine breathes, runs, and generates power. That narrow focus has allowed the brand to refine each product to a level of precision that serious racers and trail riders alike have come to rely on.
The Pro-Flow Intake System: Engineering Clean Air
Pro Design is perhaps best known in the powersports world for its signature air filter systems. The Pro-Flow line addresses one of the most common performance bottlenecks on stock ATVs and motorcycles: a restrictive OEM airbox lid and filter setup. Pro Design's solution uses a billet-machined aluminum base with precision O-ring sealing that allows the filter to remain securely in place even with the airbox lid removed — maximizing airflow without sacrificing filtration integrity.
For riders looking for a complete upgrade in one box, Pro Design's air filter performance kits bundle the billet flange, high-volume foam or K&N filter, a pre-filter wrap, and all necessary mounting hardware together. The result is a bolt-on intake upgrade that can meaningfully improve throttle response and help protect the engine from dirt and debris — potentially saving hundreds of dollars in engine repairs over time.
Cool Head Cylinder Head Technology
On the engine side, Pro Design is well known for its "Cool Head" polished cylinder heads, which are designed and manufactured in the United States. These precision-machined engine cylinder head components are engineered specifically for ATV, side-by-side, and UTV applications. The Cool Head design improves combustion efficiency and thermal management — critical factors for performance riders who push their machines hard in demanding conditions.
Race-Proven, Rider-Trusted
What sets Pro Design apart is a commitment to race-proven development. Every product in the lineup is designed with the input and demands of serious competition riders in mind, then validated under real-world conditions before reaching the consumer. Whether you ride trails, compete on the track, or run a watercraft, Pro Design's precision-engineered components are built to handle the pressure.
