NAMRUA NX-40026-B. B PISTON KIT.
Piston kits come with the piston individually wrapped; a set

of OEM quality rings packed in their own box, a wrist pin, and circlips.
Our piston kits are direct replacements for OEM piston with no modifications or dimensional adjustments needed. Combine this with the MOS2 coating and hard anodizing, Namura gives you a higher performance piston without the higher price.
We offer a variety of oversizes to meet your needs. They are

offered in 0.25mm increments, from the -1 (0.25mm over) through the -6 (1.5mm over) for most applications. We also carry B (0.01mm) and C (0.02mm) pistons, which help extend the life of your expensive Nikasil�, Boron Composite, or Ceramic Cylinders. Why replace your cylinder when you can replace the piston for a fraction of the cost at a time? We also offer a selection of big bore kits.
