This is the new VRP 6 Hole 1.3 Low-Low Pack Game Changer for the Hot Bodies/Losi. This is another

option in the growing line of Gamechanger Pistons. It is just like our current 6 Hole Gamechanger, 

but has less pack to help absorb the bumps and imperfections in the track surface better. But, it also 

maintains the high speed packing just like our other Gamechanger Pistons.

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!
