MODEL: MUGEN MBX8R / SPARKO (16mm) | REF: SERIES #18400/#18410
Your ultimate technological advantage. MIP Bypass1™ pistons represent the evolution of RC suspension engineering. Unlike traditional static systems, Bypass1™ technology puts active oil flow management in your hands.
Developed under strict dyno testing (Dyno-Tuned Technology), these pistons replicate the compression curve of your MBX8R's stock components, but allow you to unlock unprecedented rebound (extension) adjustment via interchangeable membrane valves.

The Bypass1™ system uses valves of varying thicknesses so you can modulate the shock's return speed.
| Color | Thickness | Behavior | Recommended Use |
|---|---|---|---|
| GREEN | .003 | Fast Rebound | Rough Track / Low Grip |
| BLUE | .005 | Medium Rebound | MBX8R Standard Setup |
| CLEAR | .007 | Slow Rebound | Big Jumps / High Grip |
Stacking valves allows you to create a progressive damping curve. By placing a thin valve (.003) followed by a thick one (.007), you get a fast initial response that progressively stiffens, ideal for technical tracks.
Is it necessary to change the shock oil?Generally, no. Dyno-Tuned technology is designed to work with your usual oil. However, if you are looking for extreme reactivity using green valves (.003) and still find the suspension slow, you can reduce the oil viscosity by approximately 30-60 CPS (cSt) (equivalent to dropping 2.5-5.0 WT) to compensate.
