Genuine A-Kit Performance.
Half The Price.
We convert your stock components into a $10,000 Factory Suspension system for $6,500. Same coatings. Same internals. Better value.
Unlock "Factory Confidence"
The difference between 4th place and a podium isn't just speed—it's trust. Trust that your bike will stick, not kick, when you commit to that gnarly line.
HPThe HP Solution
Friction is the Enemy
We apply Diamond-Like Carbon (DLC) and Kashima coatings—the same stuff used on $10,000 Showa kits—to eliminate binding. This allows the wheel to track the ground perfectly.
Hydraulic Safety Net
We install the 18mm Shock Shaft and custom internals to displace more fluid. When you case a jump, it doesn't clank—it absorbs. It turns a crash into a "save".
Stock Suspension is Holding You Back.
The Reality: You hit a braking bump, and the front end dives. You over-jump a tabletop, and your wrists take a violent metal-to-metal impact. As Pro Circuit technicians admit, stock forks "bind" under load because of friction, causing harshness that arm-pumps you in two laps.
The "Stock" Problem
Standard re-valves only change oil flow. They cannot fix the physics of cheap metal and high friction.

"Riding stock suspension is like driving a sports car on economy tires. You have the power, but you can't put it to the ground. Upgrading to HP Race Development is like bolting on Formula 1 slicks. Suddenly, the bike tracks, the braking bumps disappear, and you find speed you didn't know you had."
The Unfair Advantage
Most riders think "A-Kit" just looks cool. They are wrong. The difference is in the friction. We target the three enemies of suspension performance: Binding, Fade, and Bottoming.
The "Binding" Killer
DLC & Kashima Coatings
When you brake hard, fork tubes flex and "bind" against bushings, locking up suspension.
The Fix: We apply diamond-hard DLC to lower tubes and Kashima Coat to uppers. These slick surfaces allow the fork to glide effortlessly under maximum load.
Result: Instant Front-End Traction
The "Hydraulic Pillow"
18mm Shaft Upgrade
Stock 16mm shafts displace too little fluid. Under heat, damping fades.
The Fix: We upgrade to the 18mm Works-Style Shaft. It moves significantly more fluid with every stroke, creating a massive "hydraulic hold-up" effect.
Result: No Fade & No Clanking
The "Pro Perch" Net
Titanium Safety System
Stock bottoming cones are rudimentary.
The Fix: We install a Titanium Pro Perch that acts as a secondary suspension system in the last 3 inches of travel. You can over-jump into the flats and the bike just soaks it up.
Result: No Broken Wrists
We Don't Buy A-Kit.
We Build It.
Competitors charge $10,000+ because they sell you brand new aluminum castings. We achieve the exact same performance by precision-machining and coating your existing high-quality cores.
The Strip Down
We disassemble your forks and shock to the bare metal. Every seal, bushing, and o-ring is discarded.
The Coating Lab
Tubes are sent for DLC (Black) and Kashima (Gold) application alongside Factory team components.
The Re-Engineer
We toss the stock pistons. We install JBI-Spec sub-valves, custom shims, and the 18mm Shock Shaft.
Dyno Verification
Every build is dyno-tested to ensure the damping curve matches your weight and speed perfectly.
Frequently Asked Questions
Everything you need to know about the conversion process.
Q: I’m an Amateur/Vet rider. Is this overkill?
Absolutely not. Vets often benefit more than Pros. Why? Safety. The superior bottoming resistance and "hold up" mean you can make mistakes—like casing a jump or overshooting a landing—without getting hurt. It transforms a crash into a "save".
Q: Why shouldn't I just get a standard $1,000 re-valve?
A re-valve improves oil flow, but cannot change the physics of the materials. Stock tubes have higher friction. Stock shafts displace less fluid. Our Factory Conversion changes the metallurgy and hydraulics, providing performance a simple shim-stack change can never achieve.
Q: Will this suspension feel too stiff?
Common myth. "A-Kit" does not mean "Supercross Stiff." Because we use high-end coatings (DLC/Kashima), we drastically reduce friction. This allows us to valve the suspension to be plush on small braking bumps while relying on the hydraulics to stop bottoming.
Q: How does pricing compare to Showa or WP Kits?
A full Showa A-Kit costs ~$10,000 and requires aftermarket triple clamps ($800+). Our Factory Replica Package is $6,500. We utilize your existing outer castings (excellent quality) and replace all moving parts. You get 100% of the performance for 65% of the price.
Q: Does this work for WP Air Forks (AER)?
Yes. We highly recommend converting WP Air Forks to a Spring Conversion (6500 Kit) as part of this build. This removes the inconsistent "air pressure" feeling and gives you the reliability and planted feel of a coil spring.
Q: What is the turnaround time?
Unlike purchasing new A-Kit which can have months-long backorders, our typical turnaround for a full Factory Makeover is 2-3 weeks from the day we receive your components.
