the pistons do not come with optional pistons , since you will not have to change the compression piston in about two weeks i will be able to sell just the rebound piston since that is the one that will need to change. although the only change i have needed from track to track has been oil. i sale the drill sets so you can alter hole sizes to fit your needs.

the rpm pistons were made to fit only the traxxas brand of shocks, which goes along with rpm's current lineup of products (mostly for traxxas cars). anyway, what is the website for these pistons? i want to try some out!

No wonder no one used them. They were never made for a performance car!

What weight of shock oil do you recommend to start with for an rb5 with bigbores? (medium size indoor clay track)

Just a couple questions. These pistons look and sound great, but because they are thicker than the standard piston, do they change the amount of travel/droop that you are able to achieve? Also lets say I have a setup that works well, and I change out my stock pistons for these, should I start with the same oil or go up or down oil weight? What about springs? With less rebound dampening have you found it nescesary to go to lighter springs to help prevent the pogo effect?

Also MantisWorx you've got a PM

Glad to see you go public with these Marcus. Hope you sell a lot of them.

Actually they had some that were for Associateds as well. But like was said before they had fitment issues.

I have wondered why it has taken so long to get this in RC. Almost every other performance shock in off road is at least two stage. I want to know when the four stage shock is coming out?

Are different springs suggested to offset the different rebound rates?

Hi Marcus - what about pistons for Schumacher big bore shocks? Can you post them to europe?

He doesn't have any Schumacher shocks that I know of. You're in luck though as I do own a pair of Schumacher big bores and can let him borrow mine to measure. Keep in mind he's backed up with current orders and still needs to design them for other manufacturers shocks as well so it may be a little while yet.

Marcus has more experience than anyone with these but my personal opinion is that springs have nothing to do with dampening shock or rebound and which springs to use should be determined separately. He's played around with many different combos in regards to dampening and rebound rates. He can chime in on how to potentially adjust them but he's probably standing in front of the cnc right now though.

Aye sure. I'm really wondering how much difference would it make on Cougar and Cat.

Thanx for the cover Fred! you can read my mind, im actually a little overwhelmed at the response, just canceled my racing for this weekend as it looks like i will behind the machine!

let me try to explain a few things about setup, the car will be very agile and transition quickly some will love this some may not but it will be quicker this way. Grip is increased all the way around.i found that at our hard bite track i have to run full sway bars to slow the front down a little bit but at the loose track i only run the rear bar (4w buggy). Your going to have to "wipe the slate clean " and start over with shock tuning. dropping the car off of the table does absolutely nothing, i think we all do this (i am guilty to) because we know the "feel" of what we are looking for. if you do that with these pistons it will slap the ground, just like if you took a real car and dropped it two stories! hopefully some of my testors will chime in and give their experience but in general on the bench the car will feel springy and soft but on the track it is much stiffer and more normal, you will notice that your dirt trail will stay constant and you wont hear the motor pulsing down the straights. this means the tires are staying on the ground and you are accelerating faster.
Jumping is probably the most exciting thing about them! your car will jump higher and farther than before and this can be a huge advantage at some tracks at least until the secret is out!
Oils: start light most of the setups are using 30ft 25r in low bite go up 5 in high bite. keep in mind that even if you chassis slap because of the quicker rebound it does not effect or upset the car nearly as bad as single stage pistons.

Lochness, i can ship anywhere and it will make a difference on any car, a shock is a shock!

Alter, the bottom of the piston is the same , the top is thicker but if you are bottoming out your shock something is wrong anyway, i always run shock stops to keep from bending dogbones. i also sell shock stops on the site.

Well if it's able to improve grip in low grip conditions without sacrifice of other aspects of handling - I'm taking at least one set I certainly want to give it a go
