This is an optional Competition Suspension CNC Machined 8-Port Optimum Flow Tapered Piston Set "B", and is intended for use with the Losi 8IGHT family of vehicles. These pistons have been developed and manufactured by Competition Suspension Inc. to provide enthusiasts with a shock piston that has been engineered specifically for R/C applications. CSI engineers developed the Optimum Flow Tapered Piston with varying port sizes to affect the dampening curve of the shock as the shaft speed increases, allowing the tire to return to the surface faster, without producing a hydraulic effect.

Piston Rates:

  • CSI A (BLACK): Re- engineered to provide increased dampening forces for smoother tracks that have a high bite clay or blue groove surfaces. CSI A pistons should be used with oil viscosity in the 30wt to 40wt range or 350 cSt to 500 cSt.
  • CSI B (BLUE): This is CSI’s base line piston. It is engineered to provide excellent grip and more control as shaft speeds increase. The enhanced flow minimizes hydraulic lock, giving your shock progressive dampening forces, making them a perfect fit for most track conditions. CSI B pistons should be used with oil viscosity in the 40wt to 50wt range or 500 cSt to 750 cSt.
  • CSI C (RED): CSI engineers have re-designed this piston to provide progressive dampening forces like the A and B pistons. This piston provides the most flow and is ideal for tracks with lower grip levels. CSI C pistons should be used with oil viscosity in the 50wt to 70w range or 500 cSt to 850 cSt.

NOTE: It is recommended that these pistons are installed with the tapered side facing down to improve rebound dampening. The same piston set should be used in the front and rear shocks, with changes in shock fluid weight to adjust the balance of front to rear dampening.

What a difference! Have an Eight T 2.0. It has gone from a good running truggy to an amazingly stable machine. I'm running blue pistons all around with 70/60 losi oil and it is so much more hooked up, especially in the rear end. The rebound is much faster, and coming off small or big jumps it just lands and goes. The front is more stable also. I thought it was just me and wanting it to be better, but when I had a guy comment after the main about he'd never seen me run it as well, and once he drove it, all he said was wow........(had to comment twice about,I need my radio back) lol someone else drove it to and he was very impressed also. A great tuning tool!Yeah, I'm sold...
