RB Products Piston/Sleeve
This is a replacement RB Concepts .21 Piston and Sleeve, and is intended for use with the RB Concept BX and BXR .21 nitro engines. It is also a direct fit replacement for the older 01146-53 piston/sleeve, so it will work perfectly in the C5, C6 and Buggy 9/10/11 line of engines. You will need to detach the old connecting rod and re-attach it to the new piston/sleeve during replacement. We recommend that when you replace the piston/sleeve on any engine, you also change the connecting rod and wrist pin clips.
