I recently built a new Tlr 8ight ebuggy. And wondering if anyone is running the vrp split Pistons on their 4.0 and would give some feedback on it? Thanks

Anyone who has broke a piston has not been using the provided washers that come in the package with the pistons. On our original X line of Pistons, I personally ran them for 6 months before VRP ever started selling the pistons with zero breakage.
As long as you assemble everything on the shock shaft per the instructions, Your fine.

I have them in both of my Tekno sct410.3 and Tekno SL for about a year and a half now with no issues.

Hi, I recently bought the XV2's (from AMAIN) for both the B5M and D413. Today I finally got around to installing them on the B5M.
The hole in the piston was too small for the shaft. I wasn't sure if it was a defect or I was supposed to ream it so I just reamed it. However, the washer holes were too small as well. I probably could have reamed them as well but when I was test fitting the piston, it didn't appear the Piston and the washer would fit, and still be able to fit on the e-clip to hold them down. I just left off the washer and kept the e-clip and it seemed fine.
THe D413 one I have yet to open but the shaft is even wider than the B5M's, and it appears the holes are same (too small). Just wondering if this is normal or what?
Edit - Just saw that the tip where you put the piston on is smaller for the D413 then the rest of the shaft, so it probably will be fine. GUess my question is just for the B5M. Wonder if the wrong hardware was in there?

I dont see the game changers listed for the tekno sct410.3, would they be the samr as the eb48.3? I know the piston size is right because they use the same size pistons but a different hole size and configuration?

I finally had a chance to try the 8X1.3 V2s in my RC8B3 over the weekend. I could definitely tell a difference through rough spots on the track and a small whoop section that always tripped the car up before. It was a big improvement in those areas. However, the issue I have with chassis slap (jumps on this particular track don't have great landings.) was magnified greatly. The car would just slam down and bounce back up on the edge of control-ability. I think the next move will be going up on shock oil weight to see if I can get them dialed in. If not, I may try 6X1.2s.

It sounds like you may have purchased the V2 pistons, But have the V1 shafts? If you are still using the e-clips, Then you need the V1 pistons.

Unless I am missing something, there is no place on the website that says anything like that. On AMain, when I typed B5M Piston, the XV2 pulls up, hence why I bought it. I've already reamed em out and installed them, guess I will see how they work.

I am running the shafts that came with the B5M CE Kit.

Depending on what battery you run, espically in that kind of heat you will need to go to 40/35 or 42.5/37.5. Some of the 4S lipos are soo heavy that you also have to adjust the oils slightly. That's one reason to try and stay somewhere around a 5200-5400mah or smaller to help keep weight down, and closer to the weight of a nitro buggy.
