To order our piston and cylinder sets with the original "OEM" 2nd ring modified to Total Seal gapless configuration specify the part number ADD-TS. These are not Total Seal brand, however, the modification to the ring is done by Total Seal for us. We remove the second ring from the piston set and have Total Seal modify our "OEM" rings. We do not sell the 2nd ring separately. I, personally, use these in all my engines. Remember: (SW) is for shipping weight. We do not stock any 40HP P/C's. If you have such a need, call and we will get you the current price and availability. |
