VRP Gamechanger Pistons 'Build Your Own' Pro Pack

This is our new "Build Your Own" Gamechanger Piston Pro Pack.  Now you are able to build your own Pro Pack with the pistons you prefer!  We are also offeing this Pro Pack a little differently than in the past.  You are basically purchasing two 2 sets of Pistons along with a  Piston Caddy, and getting the 3rd set of Pistons FREE! 

 

 

Piston Technology you can trust....

Rebound System:


First we started with our XV2 Piston and the Quick Rebound System it has. It was important to keep
the exact function of that system because its proven track performance and obvious ease of 
understanding. The Rebound Valve has been re-designed and updated to be smaller and use less 
of the inner thickness of the piston to improve durability. This minimization was also needed to fit 
another ‘system’ into a small part like a piston.
Compression System: 



This System was designed through hours of research on oil flow and pressures built at the face of
the piston from surface tension. I made 100’s of iterations refining the technology, which meant
hours and hours of programming and machining, countless shock rebuilds, test drops, test jumps,
slow motion videos, and ultimately track testing. Over the last 8 months, I have refined the invention
into a smooth working model that fits what we do in racing. The System is ‘Smart’. It senses shaft
speed and reacts as needed.         
                      
 

 

The Patent Pending CFV (Compression Flex Valve) allows the Piston to have Slow Shaft Speed
and High Shaft Speed Compression.

Slow Shaft Speed Compression: At neutral, it is as soft as any shock with a normal set of 
comparable pistons. On the bench, you will find the suspension is subtle. Its important that
this stays in the range of what we run now, it is what makes the suspension soak up bumps and
give forward grip as well as a responsive feel at the wheel. So I made the ‘Low Shaft Speed’ 
Compression very similar to what you know. 

High Shaft Speed Compression: At High Shaft Speeds like landing a large jump, the CFV will flex
and partialy cover some of the flow holes and provide additional damping to keep the chassis off
the ground. It flexes different amounts depending on the impact and the ‘shaft speed’, so it will 
respond accordingly. If for example you were to land a smaller jump, the CFV will flex less and 
provide the correct amount of damping at the time needed. Once the shaft slows down, the valve
immediately returns to Slow Shaft Speed Compression, and the damping becomes softer.

Carbon Fiber Compression Flex Valve: Engineered with 20 years of composite experience, the actual
Carbon Fiber is made in house at the VRP facility in Houston. It is unique. From the Carbon itself to
the Resin its made with, the properties are designed and taylored for the purpose. They are similar
to a reed valve for a musical instrument and care should be taken when handling them. Treated 
properly, they should last the lifetime of the vehicle. 

New Era of Performance: You will never have a buggy land, respond, settle, and be ready for throttle 
quicker than the Gamechanger Piston. Many jumps and landings become a fluid motion with no 
chassis scrub or momentum loss. The pistons also make the car more true off the face of every jump
because it does not dig in. You will find it easier to manage jumps both taking off and landing like 
never before. This makes your consistency increase and ultimately your racing success. Where the 
chassis dug in before and you needed turn marshaled, it won’t and you will continue on.......
It's a GameChanger!
