These are really interesting. I was going to ask you to build me a set for my MBX6 but I'll try em on the SCTE and see what happens before I get you to do a custom set.

On "custom" piston sets. Is it any cheaper if I buy multiple sets at a time. If I bought 3 or 4 full piston sets of the same thing would it still be $40 each?
im stuck behind the machine making pistons! havent had a chance to update the site but will tomorrow, your SCTE pistons will ship tomorrow. custom sets are cheaper if you buy more than one set PM for details

Cman, i have sold quite a few of them but have heard zero feedback, alot of people get them and dont want the comp to know they have them!! happens more than you think, you should see my "black book" of customers! LOL

People using these in the SCTE:

Are you using both washers? One on the bottom, then the small piston, then the large piston, then washer then the nut? When I put them like this, the nut seems like it sticks up a little too far up. Should I just not use the top washer and let the nut sit directly on the piston?

well I think I figured out my problem. I was running the shock shafts 2 turns out to increase droop and the nuts were sitting up higher as a result when fully compressed. I'm thinking I might have to back them in 1 - 1 1/2 turns. But we'll see. I put them together and the fit is very good. I just have to wait until Thursday to buy some 22.5 wt fluid at the track, then I'll give them a go! I can't wait to see how they run. Marcus, thanks for everything, I'll be sure to give some feedback once I run them. I have 2 trucks, so I took the shocks off one truck and will leave them as I have been running them, and I'll run the other shocks that I just built with the 2 stage pistons. First I'll run the traditional shocks to get a good baseline of my lap times on the new layout for a few battery packs, then I'll switch out to 2 stage shocks and hope to see my lap times drop!

perfect, i have been waiting for some actual laptime feedback! expect .5-to a full second in most cases. from what i hear Bill dropped about a second with his SCTE! apperently he is causing some trouble at his track with his truck, i have had a few phone calls about him!

I got a chance to run my Durango with the pistions and ended up with 40wt front, 30wt rear. Working great!

I tried 35/27.5 and it was bottoming out too much, but that was during the day, Temps were 90's during qualifiers and low 80's for the main. Ended up with 40/30 in the main. Like stock shocks Temp plays a big part from day to night racing.. I may try 35/25 next time.

I know your busy Marcus but we really need some guidance as to how to properly fine tune our setup for our trucks. Bill has mentioned that weight transfer is very different with these pistons. Not necessarily bad, but different enough to make us rethink how we work on our trucks.

I have read step one and two on the setup page but those steps already include a choice of springs. How do we determine which springs we should run with the pistons? I would like to get as much dialed in as possible before I start opening up the pistons.

You should choose your springs before you choose your pistons or oil so new pistons shouldn't have any bearing on that.

Hi Fred. How do you recommend we go abuot picking springs when using these pistons. Oil and springs have always complimented each other in the past but these pistons seem to change all of that.

TEN 4X4.. OK:
Following directions LOL I changed the set up,... to 30 30 oils with no rebound. and when working the shocks up and down like it was on the track the air bubbles took almost half an hour to get out. I am glad I did it before I went to the track. I will post my results Thursday after I get all set up at camp Santiam

Here is what I did.

Take your old setup. Don't change the springs. Drop the oil weight about 10 and go from there. I did that and it got me in the ball park. I wouldn't change your spring weight from your previous setup unless after changing the pistons, you find it necessary.

I'll agree though. We need more setup info. Unfortunately, it is not there yet. That's why it is important that everyone report their results, good or bad, so we can all learn from it.

This is a new concept, at least it seems that way to most people. There just isn't going to be much setup info.

There is a thread called "Tune with camber links" on rctech- find it and read through it. Fred details every aspect of vehicle tuning in a very easy to understand fashion. Its a long read but is definitely worth the time.
