TSP rebuild kits are put together by TSP using parts sourced direct from OEM manufacturers in Japan and Europe. The parts we select are THE BEST available for each make/model and many are the exact same parts as the genuine OEM items.
We typically recommend only using an “A” piston size for brand new cylinders or cylinders that have been replaced. The “B” piston size is typically used for any cylinder that has more than 25 hours on it.
