I was browsing on amain today and came across RPM's two stage shock pistons (http://www.amainhobbies.com/product_...edium-Heavy-12), I know that two stage shock pistons have two different pistons with different holes. When compressing the shocks, oil flows through 4 holes, and when the shocks rebound, the oil flows through 6 holes. I'm guessing that through bumps and rough sections of the track, the wheels will have an easier time keeping power to the ground, providing better traction and quicker lap times. (In theroy) When landing a jump, the truck will rebound quicker resulting in not bouncing on the landing. Correct me if I'm wrong... So it appears that these pistons fit a varity of applications, and I have a Losi xxx-sct which should work because the shocks come off the xxx line of trucks. So could anyone chime in and give me some input on these pistons? They seem to be better than the single stage losi pistons with varying hole sizes. Thanks guys!

I have seen that thread, and I looked through it, its half ordering the pistons from the guy, half telling everyone how great they are. I want to know if anyone has used the rpm ones. and I also dont want to spend $40 to send out my shocks, get them fitted, and then sent back to me. I can spend $7 on the rpm ones, see if they work well, and if they dont, no harm no foul.

I have them in my slash 2wd and they work real good. I am using the green and purple pistons. The rpm pistons fit the stock slash shocks and need to be sanded down to fit the traxxas bigbore shocks.

I run the red rpm's in my scb, they work well.
