GHEA shock pistons

Because RC shocks are primitive in design and basic in the way they work compared to other industries it’s important to understand why we tune the bits we do.

This is where we have collected all the set-up information imaginable,tested extensively and studied the dyno results in every conceivable way to be able to give you everything you need.


Having a machined piston ensures an exact match to each manufacturers internal shock body which means the holes do the work and there is no blow by where the oil runs around the pistons between the body.

This will decrease shaft wiggle when the shock is fully extended and increase the strength and support of the shock.


“Pack rack”

No more guessing-you can now tune your shocks to run the same oil between pistons and using a base setting. Your able to maintain the the same low speed damping settings with all 5 pistons but you can adjust your high speed pack setting between 10-25% in either direction.
Each piston,hole number and size has been meticulously calculated to give the piston of pack set a unique approach to tuning your RC shocks.

Allowing you to run the same oil in each piston of choice and the car will feel exactly the same on the bench.

What this means is- no more guessing which oil to use when changing pistons and knowing exactly how the car will react to changes you make.

For example: If your car is working good on the majority of the track but you have a big jump with a heavy landing and the car is bottoming out on this one section.You can increase your high speed damping (pack) by 10% and this should help your car on landing but won’t be different anywhere else.

If 10% isn’t enough then go to 20% and see how that feels.

Likewise if you are on an extremely bumpy high speed track and your wheels needs to move quicker-then you can decrease the pack.

This is a scientific approach to getting what you need from your car rather than guesswork.
