Product Description
Dynamic Velocity Pistons: DVP-Drag Spec
Our shock pistons use Dynamic Velocity Dampening to keep your car stable and increase overall traction.
What does Dynamic Velocity Dampening mean?
This is the ability to dampen suspension movement, responsively to suspension travel speed.
Our shock pistons are the ultimate upgrade for increasing traction by absorbing bumps and imperfections in the road surface, without disrupting the cars stability. They also maintain full control of weight transfer. (More on that later...)
This is the ultimate goal of suspension tuners.
Read on if you’d like to learn more about shock dampening...
Rebound Speed:
After hitting a bump, Its extremely important for your tires to get back down on the ground. The quicker your tires meet the surface, the faster they can get bite again. You can’t put the power down if your tires are still in the air. How quickly your suspension puts the tires back down is called “rebound speed.”
Spring Frequency:
Different rate springs have different frequencies. Stiffer springs have a higher (or faster) frequency, softer springs have a lower frequency (slower).
Imagine you had no oil in your shocks. If you were press down on the chassis and slip your finger off, the car would shoot back up above ride height, then bounce up and down a few times before resting at ride height again. It may be hard to actually see this, but it definitely happens.
Different rate springs need different amounts of dampening. You can imagine to perfectly control the frequency of a stiff spring, you need thicker oil for stiffer dampening. Just the opposite for soft springs. A perfect balance would let the car shoot up fast and stop exactly at ride height with no bouncing.
Weight transfer:
Weight transfer is when the weight of your car moves to different ends or corners as the car accelerates, stops, and corners. This isn’t hard to understanding or notice. It’s why drag cars squat in the rear and raise in the front. Or why dirt track cars lean as they go into and through the corner.
Another purpose of shock dampening is to control timing of the weight transfer. If your dampening is too soft, the weight will transfer too quickly. Timing of weight transfer is critical in all forms of racing.
In drag racing this can cause the car to unload both the front and the rear too soon, compromising your traction off the line..
Weight transfer should not be confused with tire loading. That is another subject and controlled by spring rates and suspension geometry. You need the correct tire loading by using the proper spring. And you need the proper dampening to control that spring.
Shock “pack”:
Standard shock pistons are inherently prone to what is known as “Shock Pack.”
This is when shock fluid velocity is too fast to flow through the small piston orifice. This in turn locks the flow of fluid, and also locks the suspension.
This can be beneficial in Off-road racing as it helps keep the car from bottoming out when landing big jumps. The problem is that also causes the car to be unstable when hitting bumps in the track.
It’s a trade off, you must find balance.
For Drag Racing, “shock pack” is bad for several reasons. The most important is stability. When your car is making a high speed pass, the last thing you want is to have a small pebble or imperfection in the track surface send your car tumbling or skidding on that beautiful body you’ve spent so many hours on.
The second reason is for the suspension to react to the surface, not bounce or “jump” any bumps in the road. Remember the tires need to stay on the ground.
So you would think the quick and easy fix is just get rid of “shock pack” all together. This can be done several ways, but unfortunately this also limits your ability to control weight transfer. You don’t want your car to flop around like a ‘79 Cadillac with no control of weight transfer. Conventional ways of reducing shock pack also limit spring dampening. As mentioned before, it’s usually a trade off.
The “Fix”:
The goal of shock tuning is to get the least amount of “pack”, fastest rebound dampening, still control spring frequency, all without losing control of weight transfer.
Until now, this has always been an unfair trade off.
Dynamic Velocity Pistons react to the speed of the shock shaft. The faster it’s moving, the less dampening the piston creates. As the shaft speed slows down, the dampening increases.
This creates the Perfect balance of stability and traction not found in any other RC Shock Piston.
Full size cars and motorcycles achieve this with different types of valving and active stability control systems.
This is not practical on RC vehicles due to the actual size of the parts and the properties of available shock oils.
Dynamic Velocity Pistons have no extra moving parts, and no complicated modifications.
You can be ready to race in no time. All you have to do is swap out your shock Pistons, and shock fluids to our recommendations and get back to racing and winning!
